Since childhood, Freen has always been taught to live by firm principles. It was her father who provided education and instilled such a mindset and Freen vowed to always stick her own principles in her head. She thought her heart would remain steadfast in maintaining that principle. But she was wrong. For the first time in her life, the principles she held so tightly were shaken.

It happened when she was 10 years old. In the afternoon, her mother who was busy cooking in the kitchen called her and asked her to buy some things at the mini market. She was given some money and a note, not forgetting that her mother ordered her to go home immediately after finishing her shopping activities.

Little Freen immediately left with a feeling of joy and bright face, imagining how many chocolate candies she could get for her change. She always loved shopping—either alone or accompanied by her parents. One reason is because she can see the outside world and the various activities people do. Workers in suits or blazers who walk quickly to catch public transportation, to students who carry books and walk hand in hand with their friends.

When she arrived home, it wasn't the warm smile that her parents usually gave her every time she got home. Nor was it the gentle pat that her father always gave on the top of her head every time Freen managed to do what she was asked to do perfectly. All she saw was the horrific sight of pool of blood from the living room to the kitchen and a body swinging in the doorway.

And she screamed, loudly. Making neighbors around her house come to find out what is going on at the Chankimha Family's residence. Some people reflexively screamed in fear when they saw what was in the house, others immediately contacted the police and arrested Freen because at that time she was still hysterical due to shock.

The results of the police investigation stated that it was a premeditated suicide case. Her father killed her mother first using a kitchen knife before he hanged himself in the living room. It seems that her father's plan did not go smoothly because her mother fights back—it can be seen from the amount of blood that was splattered in the house—although in the end her father was still able to kill her mother in the kitchen by stabbing her brutally.

Perhaps, it was that event that made something inside her heart change. Since both of her parents died in a very tragic way, Freen had to be transferred to a rehabilitation center to deal with the post-incident trauma that would probably haunt her for several years. She will also live in an orphanage considering that her parents do not have other families that can be used as guardians.

Freen still remembers that well. What kind of mischief had she done while she was living in the orphanage and undergoing rehabilitation. Even though she personally felt that she had never done what was called delinquency—it was the caretaker who gave her the understanding that what she was doing should be categorized as delinquency and therefore Freen had to self-reflect and receive a number of punishments.

After all, is pushing a boy who throws her head with gravel into the middle of the road until she is almost run over by the barrage of big wheels from a truck? Freen only does what is called revenge—payback, revenge. And again, is pulling and slicing the head of the cat belonging to the caretaker of the orphanage that drops her belongings to pieces, included in the act of mischief?

Her father always said that every action always has a consequence, no matter if it's a good deed or a bad deed. The same goes for them—bullies who throw stones at her deserve a similar response. Freen, who at that time didn't have the power to retaliate just wanted the boy to feel the same way, namely pain. The big wheels of the truck must have caused him more pain than she wanted so Freen waited for the right time to trap the boy and shove him in the middle of the road.

Well, even though the boy in question is still alive today. The last thing she remembered, he was paralyzed from his neck to his feet.

As for the cat? Hmmm, the animal made her belongings fall and scatter on the floor. The caretaker of the house didn't like that—and she also did, in fact—so of course Freen got one or two long tirades for a faux pas she didn't commit. So in order to get her revenge, Freen came out of her room at night to drag the cat to the orphanage's backyard.

She did everything there using a pair of scissors until finally she dug the ground under a tree and buried the cat there without a head. Instead of putting the cat's head and body in the ground, Freen chose to leave the cat's head covered in blood at the door of the orphanage. Look, everyone gets what they deserve. Isn't that fair?

When asked if Freen regrets, feels afraid, pity, or something like that? Freen would resolutely say no. She just did what she was supposed to do with determination. So why feel fear and regret?

She didn't know why, but maybe it was because of her personality that most people in the orphanage were afraid of her. Even though she lived like children in general. She is also a cheerful, friendly, and also very smart kid—she can solve math problems that are much more difficult than friends her age. She also has an excellent memory and intellect. You could say that Freen Sarocha is a genius—even though her slightly psychopatic personality hides her intellegency.

Freen spent several months in solitude until a married couple came to adopt her when she was 12 years old. In addition to getting a new family, it was at this young age that Freen received a will written by her father before the tragic incident occurred. The company that was owned by her father suddenly went bankrupt due to the mistake of one of the employees, plus the biggest investor—as well as her father's best friend—who should have been able to save the company withdrew funds and decided to cooperate unilaterally.

That left her father's company trapped in enormous debt. Not to mention the demonstrations carried out by the employees, to the debt collectors that came non-stop to her father's office. No wonder she didn't get any heritage because all the assets owned by her father were completely confiscated by the bank after he died—even her own house. So she knew who the people who came screaming like crazy at the funeral of her father and mother, moneylenders or debt collectors, of course. Freen read the contents of the letter with anger, and was very disappointed.

She carried those two pathetic feelings her entire life. And since she read the will that her father left for her, everything has changed. The letter became a turning point in her life, which ultimately changed her personality. She lived as a teenager who had no emotions other than a big grudge against whoever caused her parents to die in such a tragic way.

As long as she lived, Freen always tried to find a scapegoat. Or maybe, someone who is most responsible for the death of her parents. Most of her time she used to sort through old documents and records left by her father. Hoping all that relic will carry her by a name or two.

You could say her life changed one hundred and eighty degrees after she was adopted by her new family. Her adoptive father is a high ranking official in the police with the rank of Major General while her adoptive mother is a judge in a high court. If you look back, it really suits her beautiful and bright-brained self since birth, doesn't it? By the way, this new family is very kind, too kind in fact. They always supported what Freen was doing, provided facilities to support her academic and non-academic activities, and even provided expensive items that were not owned by teenagers her age at that time.

Maybe all the privileges that made her complacent. Lulled by wealth and position as if to complete the heart and feelings that have long been damaged. And we all know a person with a broken souls, when presented with something like wealth and power, is more likely to abuse what she has for her own pleasure.

Such perceptions also apply with Freen Sarocha.

At the age of 16, young Freen is now more worthy of being called a double-edged sword. She is known as a model student who is always ranked one or two out of hundreds of other students in her class. She also excels in the fields of painting and sports—you need to know, thanks to her physical ability and skill, Freen was appointed as captain of the high school basketball team. On the other hand, she is also known as a bully of bullies.

Don't you understand? Don't you remember when Freen was a victim of bullying at an orphanage? Since then she hated bullies so much that when she was a teenager, she used what she had to give a small lesson to the bullies at her school.

Several times she dragged two or three students who were caught bullying in front of her eyes—no matter they're a boy or girl to the gymnasium, then beat them with her bare hands or beat them with a baseball bat before leaving them with frightening threats and a sharp look in her eyes that terrifying. Threats always work, obviously, because well... who would risk their life to come face to face with Sarocha Chankimha? Only fools would dare cross that line.

She uses her intelligence and influence to manipulate people's minds, including changing their perception of her. If she knew that someone thought of her as a bouncer delinquent, she would immediately show another side of her that was as good as an angel in front of many people. Freen has many faces, and she can choose which one to show others at will.

Her father loved her dearly—and Freen remembers how happy he was when she announced that she would follow in her father's career and become a police officer at a family dinner when she entered her third year of high school. Even with her mother. She fully supports Freen's ideals with all her heart. Even when taking the entrance exam for the police academy to accompanying her daughter to enter the hostel before undergoing education, her mother sobbed like she would lose her daughter forever.

She graduated from the academy with excellent grades and was immediately placed in a regional office in Chiang Mai. People know her as a very competent cop. Every case that is handed over to her, is almost always well resolved—although a few people already know that behind her charismatic, friendly, and smiling face, she is a sadistic and unforgiving person. There are countless criminals who end up battered or lying in a coma in the hospital, if they are unlucky.

Her name itself is already widely known among the criminal group based in Chiang Mai, and most of them will go into a frenzy if they hear the news that they will soon be arrested by Second Lieutenant Sarocha Chankimha.

Still remember the background of Freen's father? Hey, even though her father has a high position, she still fights for her career with her own ability. Well, even though her father's influence without her knowing is still playing behind her. However, during her career in the police, starting from when she was still a cadet until she had tasted the rank of captain, the only moment where she needed her father's power to protect her career was when she shot six civilians along with three robbers at once.

At that time God was on her side. With her father's influence and power as well as the image of an exemplary police officer that has been firmly attached to her, Freen is able to drag opinion and distort reality so that the incident actually brings her luck. The media reported the incident as a heroic action by a policeman trying to save the hostages. The number of victims was successfully manipulated so that all media only mentioned three victims from the original number of nine.

In that incident, they created a scenario like this; there was an armed robbery accompanied by hostage-taking at a branch of a privately owned bank in Chiang Mai committed by three recidivists. Several police officers and anti-terror officers were assigned to the location to deal with the situation without causing any casualties. But at one point, the negotiation efforts failed and the three perpetrators caused chaos by shooting randomly at the police who were still trying to negotiate to save the hostages—including Freen. Unfortunately, the bullets hit the hostages and killed them.

In fact, if the crime scene was investigated and evidence examined, the bullets that lodged in the bodies of the hostages who were victims matched the bullets used by Freen and were very different from the bullets used by the perpetrators. Of course we all know what happened to the real bullets, right? Exactly. It got exchanged and destroyed.

Even when the internal police investigation was carried out privately, Freen could easily answer that the shooting incident occurred because the three perpetrators tried to fight back by shooting at the police, so Freen also made an effort to protect herself by killing all the perpetrators with shots in the head—what about the hostages who were also killed by the gunshots? Well, whose fault were those people screaming hysterically like crazy? If only they had calmed down, maybe they wouldn't have been shot.

The statement of self-defense submitted by Freen was also accepted by internal parties. So that her father's cronies can continue the rest of the work easily. Call it the payment of hush money to all parties who become eyewitnesses—actually not only hush money because Freen is sure that her father had ordered a certain group to completely shuts down the remaining evidence. What they were doing, Freen neither knew nor cared.

Supposedly, after carrying out the spontaneous killing, Freen would have been dishonorably discharged from the police force. Even worse, she may be sentenced in public in an open trial with a jury that will make her sentence even more burdensome. In fact, she only received a demotion and was transferred to another city—Bangkok to be precise. Thanks again to her father's influence and power in police and political circles.

Is she feels sorry for what she did? Had she regretted seeing the many pools of blood on the floor, the smoke billowing from her gun, and the bullet casings splattered under her feet?

No.

She never regretted for what she did. Why was she regretting what had happened? After all, the lives of the nine people also would not be able to return if she acted melancholy. What Freen does always has a reason, she also has her own reasons why she shot those people her gun.

That's right, everything that happens... must have a reason behind it.

After giving Becca a spare keycard and giving her a little room tour, Freen immediately said goodbye to return to the office. Before leaving, Becca offered to do the cooking and Freen, who was not used to getting questions like that of course stood silently in the doorway with a confused face.

Becca felt that odd air of awkwardness too because she had just realized that she seemed to be talking to her own wife who was leaving for work—which she wanted to bang her head against the wall upon realizing. Freen as her future wife? God, she would be filing for divorce in a month at the most if Freen married her one day.

Becca sighed in frustration at the thought. Besides, let's see what kind of expression is on Freen's face? She looked even more annoying with that surprised face. "It's not like I'm going to treat you like a lover, wife, or anything like that okay? I just wanted to repay your kindness," giving in, deciding to break the awkwardness between the two women, Becca took a deep breath before continuing more gently, "What. Do. You. Want. To. Eat?"

"A—Ah?" The Chankimha suddenly gasped, was at a loss assembling a sentence. Although in the end she still answered, "Up to you...? Or maybe we can order through a delivery service instead of you having to bother cooking in my kitchen."

"So you're saying that I'm a bad at cooking?"

"It is not like that!" Freen released her grip on the doorknob. "You are a guest in my apartment. So—"

Becca exhaled, turning away from Freen waving at her, "Okay. I'll just make tom yum." She answered while opening the fridge and starting to look for what she needed.

"Whatever. Just... don't set my kitchen on fire," Freen said again. She opened the door in front of her while occasionally glancing at her cellphone screen to check whether the online taxi she ordered was already in the apartment lobby or not. It wasn't that far away already, so it was better for her to quickly go downstairs and wait. "Armstrong, looks like I'll be home a bit late. So please lock the door, okay?"

She could hear Becca say yes from inside. That was enough to make Freen feel relieved that she heard her words so she immediately closed the door, locked it, trotted down the elevator to go down to the apartment lobby. Luckily the conditions were quiet so she didn't have to wait for the elevator to stop by to another floor and waste her time.

In less than five minutes, Freen was on the first floor. Without waiting for a moment, she immediately walked towards the lobby and looked out the glass door. From a distance she saw the lights of a car moving towards the lobby. The car's license plate matched what was written on the application, so it was clear that the car was an online taxi that she ordered some time ago.

The trip to the office felt so fast because Freen had fallen asleep in the middle of the road. As soon as she woke up, the taxi was already at the main gate and was being checked by security. She immediately rubbed her eyes and prepared some money to pay for the taxi fee when she got off later. A few minutes later and after completing the transaction, Freen immediately headed for the elevator—ignoring the other personnel passing around her.

To be honest, while waiting for the elevator, she felt several pairs of eyes staring at her from a distance. But she didn't care about that and decided to go inside as soon as the elevator door opened.

As soon as she arrived in front of the investigation team's special room, the young lieutenant immediately pushed the door open. Freen immediately dropped her phone on the table before joining Noey, Heng, and Irin. Heng appeared to be standing in front of a blackboard full of photos attached, small notes written with a ballpoint pen, as well as red and black lines inscribed with a marker. The crime board is getting more and more full, Freen thought.

There are quite a lot of photos stuck there. Starting with a photo of Sergeant Rebecca Armstrong which was placed at the very top, then below it is a photo of the alleged perpetrator of the murder—a photo obtained from CCTV footage—then below again, a photo of the four victims including a description of their nickname and photos when their bodies were found. Scattered around the photograph are investigative notes, including details found by police and clues. Then back up, Sergeant Seng Wichai's photo was placed next to Becca's photo, with two successive arrows pointed at Becca's photo.

Indirectly, the arrangement of the photos says that the killer ordered Seng to kill Becca.

"That crazy bastard still insists that he attempted murder on the orders of someone who contacted him on a disposable phone. He was threatened, and severely terrorized for two full weeks until he finally agreed and carried out the murder plan as ordered." Heng explained as Freen stood beside him. He glanced at the lieutenant's somber face out of the corner of his eye, knowing that the woman looked intently listening. "There have been four victims each with the first name ARMS in order. It's becoming increasingly clear the murderer we're looking for is deliberately offering these victims to Becky."

"I've been looking for people Becky has worked with over the last five years. Including checking the records of all the cases she's handled so far," Noey stared blankly at the pile of files covering the view in front of her eyes. The tufts may be up to 20cm high. "No one could potentially hold a grudge against Becky. There is also no one who has the same characteristics as the woman who appeared on the CCTV at her house. Looks like we need to ask her family about this."

Freen chuckled and walked back to her desk. Standing at the front and wracking her brain in front of the crime board really made her head stir. In murder cases like this, Freen always tries to put herself in the killer's shoes. If I was the killer, what would my next step be?

"That's right. What about the Armstrong Family residence? Did the personnel assigned there get anything or maybe they spot unknown people hanging around there?" Freen asked again. "At a time like this, they are the ones at a disadvantage."

Irene shook her head. "So far no reports have come in. So the situation is still pretty safe." The young lady then turned to Heng as she stood up from her seat. She also grabbed the jacket that was draped over the chair. Looks like she's going somewhere. "Heng, I will go to search the Seng house with the others now. There was something odd about that place and I wanted to come back to pick up what was left. Do I still need a warrant?"

"Of course, just a moment," Heng got up from in front of the crime board and headed back to his desk to take out a blank assignment letter from the desk drawer. After providing some information and signing the letter, he handed it over to Irin. "Noey, I hope you aren't going anywhere because I need you to help me with this fucking boards right here."

Noey typed something on her laptop keyboard, "Okay, boss."

After Irin left, Freen felt she had nothing left to do. Well, actually there is. But she felt her head would become dysfunctional if she continued to insist on staying in a room full of personnel arguing about cases. Frustrated, the woman finally took her phone and walked out. Besides, she had to meet Mind after this because she intended to take her to the Central Institute Forensic Service.

After receiving affirmation from Heng who is now the head of the investigation team, Freen immediately went out into the corridor. She had messaged Mind to pick her up at the office, the woman herself also confirmed that she was on her way and would be arriving in a few minutes. There was still time for her to stop at the vending machine and buy three cans of coffee. She felt that she would spend a long time in the forensic office. So since she didn't want to fall asleep and lose focus, Freen decided to down two cans of coffee and save the rest to give to Mind.

Freen awaits the arrival of the criminal profiler and childhood friend in the lobby. So when a black BMW car with a combination of license plates that she knew started to enter the office area, Freen could see it and immediately waved. The car stopped in front of the lobby and Freen got in quickly so the car could leave and not be shouted at by the security guard.

"I thought you'd ask me to meet and talk at your office," Mind said. Freen placed the canned coffee on her lap and the woman muttered a thank you before moving the cold canned drink elsewhere in her car door.

Freen exhaled heavily. She looked so tired and the two cans of coffee she drank did not help get rid of sleepiness. With a limp tone, she replied, "We have no time, Mind. I'm taking you to see the forensic team perform post-mortem procedures so you can get a better view of this one. Urgh, I can't even look at it. Too terrible."

"Oh," Mind nodded in understanding, "You sent a photo of the corpse via LINE while I was having lunch. Really polite."

"I'm sorry, okay? How would I know you were eating at that time. I'm a cop, not a psychic or witch or anything like that."

Hearing the woman beside her start protesting with a grunt, Mind couldn't help but chuckle a little. This old friend of her hasn't changed much after she was adopted by a rich family and started a career in the police—in her eyes, Freen was still like a wimp who would answer your words in a tone that was as annoying as the expression on her face.

"Mind," after several minutes of silence, Freen finally spoke up. She looked down, her eyes fixed on her hands clenched tightly above her thighs. The woman looked nervous and panicked at the same time and Mind was momentarily stunned. "I don't want to do the same thing twice in Bangkok."

Do the same? Mind's forehead furrowed deeply. She paused, trying to digest what Freen had just said. In the next instant, reality hit her like a lump of steel dropped on the head—Mind was fully aware that Freen was referring to the bloody incident she was involved in. What... There's no way she'd do something like that again, right?

But instead of showing the same anxiety, Mind tries to hide and control herself. She tried to stay calm and replied casually, "What? What are you doing? Don't tell me you're messing around with the girls you just met at the bar?"

"That mouth of yours—" exasperated half to death, Freen reflexively raised her hand as if she was going to slap Mind's face even though in the end she withdrew her hand and didn't end up slapping her friend's face. It could be bad if they had a single accident just from slapping each other in the car. Finally, without raising her hand on Mind's face, Freen replied curtly, "I... don't want to eliminate more people who know my secret, Mind. After all, I had erased all those terrible memories and started all over again here. Hearing that someone knows about the shooting incident... makes my stomach turn."

"Who are you referring to?"

Freen gulped. Her tongue was numb for a few moments. "Sergeant... Rebecca Armstrong."

The mind exhales slowly. The shooting incident Freen was referring to was a dark secret that no one should know about, a secret that should live on as rumors that would dissipate in a week or three. Usually Freen didn't care about that, but this time she looked nervous and scared because someone named Rebecca Armstrong knew her secret.

To be honest, it was a new thing and Mind never prepared an answer because she didn't know a moment like this would come. "I dunno, Freen. Maybe you should talk things over with this woman named Rebecca. It is better for her to know everything from you than to know it from someone else's mouth."

"You say it like it's something so easy to do. I'm trying so hard to maintain her trust. This kind of thing can make what I've been building all this time crumble in less than a second."

"Wait a minute, since when did you start trusting other people?" Mind answered quickly. While Freen only smiled faintly while looking at her friend's shocked face from the rearview mirror.

They both arrived at the CIFS office an hour later. After tidying up their appearance, they immediately entered the building and showed their IDs to the officers on duty there. After conveying the purpose of arrival, the officer offered to accompany Freen and Mind to the room where Doctor Nam's forensic team worked, which Freen immediately accepted.

The officer escorted them to the 3rd floor, right in front of the double doors marked with the autopsy room. The door was opened and there was another room surrounded by transparent glass equipped with curtains. Doctor Nam has just come out in a bit of a hurry from her personal office which is next to the autopsy room, she welcomes the arrival of the two young women.

"Ah, Lieutenant Chankimha," Nam greeted. She let the two men inside and closed the door again. The forensic doctor also escorted them into the glass room to see the corpse which was still under observation. "Heng already contacted me if you were coming. At first I was a little surprised because it was usually Becky who came to monitor the autopsy. But then he told me Becky was being given a dispensation."

Freen muttered and nodded. "Yes. Sergeant Armstrong is currently undergoing therapy at the facility and will be back within the next month. I will taking over her job."

Hearing that Nam nodded. The woman's shrill voice then sounded again, "And the person beside you? New personnel again?"

"Ah, no. This is Sawaros Nekkham, the criminal profiler I was telling you about. And Mind, this is Orntara Poolsak. She's a forensic pathologist who works closely with the investigative team to autopsies the bodies of serial killer victims."

As Freen finished introducing each of them, Mind and Nam took a few seconds to shake hands with each other. They chatted briefly to lighten the mood before jumping into the main topic which was the reason why Mind and Freen came to the CIFS office.

Nam hands Freen a sheet of paper with notes on the autopsy progress that are stapled to a board. Taking new rubber gloves that weren't stained with blood and putting them on skillfully, Nam walked back to the corpse holding a small flashlight. "Reconstructing her head was very difficult because her skull was completely shattered. One eyeball was also missing and the officers who went down to the crime scene were unable to find the missing eyeball, even though they had been searching for several hours. I suspect the killer had eyeballs with her."

Nam used the flashlight to illuminate the victim's face which was filled with stitches. The forensic team really worked hard to restore the shape of the victim's head to that of an ordinary human head, even though it did not completely return to its original state. But at least the remains of her bones and head were not scattered on the floor and operating gurney.

Indeed, there is a missing eyeball and in the empty part where the eyeball should be, there is a fairly deep scratch. The same wounds were also found on the temples and eyelids.

Freen chuckled and looked the other way and rubbed her face with her palm. The rough touch landed right on the claw wound on her face so that she hissed with pain for a few seconds. Seeing the patchwork condition of the corpse made goosebumps run down her spine so she decided to listen to Nam's conversation from afar while reading autopsy records from previous victims.

"Are there any missing body parts from previous victims?" Mind finally asked.

Nam nodded and turned to Freen. The woman seemed to understand and brought the autopsy report files she was reading to show Mind. "Most of the victims lost several fingers, tongues, and wrists. But all of them were found in the victim's throat. For this one, we didn't find an eyeball in the throat to the stomach."

"Freen already told me that her way of killing has completely changed in this fourth victim. Coincidentally, the investigation team managed to get one witness who actually saw the killer in person and her features also matched the woman who appeared in the CCTV camera footage," Mind crossed her arms over her chest. Her face scrunched up, seemed to think deeply with all the assumptions in her head. "Hey, why do I get the feeling that the killer we're looking for is right around us? She changed the way she killed her victims and made the crime scene even more messy after the police found a bright spot. The goal is clearly to confuse the police, and nothing else.

"You can assume, but we still have to look for evidence." Freen answered from behind. The woman went back to what she was doing—going through everything in the autopsy room, including computer equipment, microscopes, DNA duplicating devices, and so on.

Looking back, making sure that Doctor Nam was busy talking to Mind in front of the corpse that was being dissected for autopsy purposes, Freen walked sneakily leaving them to enter Doctor Nam's private room which was separate from where they were dissecting the corpse. The formalin smell that she had smelled since they entered the autopsy room became even stronger when Freen stood at the door.

Formalin is a liquid used to preserve corpses. If so, the smell should be centered in the autopsy room and not in Doctor Nam's private room. In general, Forensic Physicians or people who work with cadavers will try to avoid such odors in places other than they are performing a dissection as much as possible. It was done with the aim of erasing unwanted memories when they cut and dissect corpses.

But this... Doctor Nam actually had a stronger odor in her private room. It might be a small detail that most people would miss, but to Freen it was still something unnatural.

Turning the doorknob with a gentle and cautious movement, Freen heaved a sigh of relief as soon as she found the door unlocked. She enthusiastically pushed open the door and opened it slightly. There is a yellow box placed on the table. The box was closed tightly with cardboard and plastic tied by a rope, to open it might take a little more time and effort.

However, even though the yellow box was tightly closed, Freen managed to find an opening so she could peek at what was inside. As she had expected, it was the object in the box that was the source of the stifling formalin smell that filled the entire room.

Inside there, there were lots of used formalin bottles that were empty. And Freen swears she saw tons of brown stains like old blood marks stuck to the surface of the bottle.

What the hell is this?
