Y/N's POV

I woke up with a really bad headache. I sat up and started massaging my nape since I slept on the floor? What happened? I can't remember what happened I also don't know what time it is. Then I heard a scream. I quickly stood up and searched for the source of the noise.

After a few minutes of searching, I ended up in a living room. But then I noticed there were three unknown men so I took cover.

One was standing and towering over the two. They were badly bruised. What has this awful man done? The men were tied up in a metal chair, both their hands and feet were red from the tie marks. While the man standing before them was holding pliers.

That's when I noticed that the two guys were crying. Tears, blood, and sweat were mixed in their faces and body. The pliers were coated in blood. Beside the man was a rusty surgical washbasin. Inside the basin were fingernails, what the fuck?

He removed their nails. He's torturing them.

That's when I noticed this whole scenario. The two guys that were tied up were the two ghosts that I saw before I fainted. Just in time, their captor moved his head to the side and I was able to get a glimpse of his face.

Why does he looked familiar?

The moment he turned around I felt like cold water was poured over me. Jungkook. It was Jungkook who did that? How is that possible? Why? I felt my chest tighten once more. I can't breathe. Everything felt small until it all turned black.

>Flashback<

Jungkook was slicing up his victim and taking out its organs when the door busted open. It was his friend and his boyfriend, talking and laughing, oblivious to the man that was busy. Until they arrived at the kitchen. Their eyes went wide at the scene in front of them.

Jungkook was busy dividing the body parts and putting it in different containers. He was so focused that he didn't notice the two figures that were trying their best not to freak out.

"J-Jungkook what are you doing?" Taehyung stuttered from behind him. While trying his best to not faint.

Just then Jungkook turned his head to look at his friends. He quickly realized what they saw and tried to defend himself but Jimin beat him to it.

"Jungkook isn't that the bully who pushed Tae off the stairs? What have you done?" Jimin shouted.

"Hyung let me explain, I-I just did what I had to do. He hurt you guys. He deserves it!" He said defensively. Hiding his heart that was hammering inside his chest.

"But this is not the right way to do it Kookie! You should have just reported him?" Taehyung reasoned out. He knew there was something weird about Jungkook, but he loved him. He loved him way too much that he'll accept whatever it is.

Jimin just scoffed and looked at Jungkook disappointedly. "So it is true? All the rumors weren't rumors at all! It was facts! You killed your parents! You're a monster!" he spat. His knees may give out on him but because of the adrenaline his courage doubled.

Jimin then turned around and ran away leaving Jungkook and Taehyung behind. "No Hyung! Please don't go." The boy pleaded. It was good in a way, but he can't let his friend rat him out.

"Let him be Jungkook. He'll come by I promise." Taehyung held his arm when he was about to go after his friend. He assured the young boy while patting his back. Even if he was scared he knew that Jungkook was unstable, leaving him behind wasn't an option.

That night Jungkook revealed his dark past to Taehyung, every little bit of it. He felt vulnerable but at least his boyfriend accepted him. The only downside was he was asking him to change, to stop everything.

But he wasn't sure if he wants to. If he can do it.

Jungkook had a rough childhood. His mother was a taxidermist, while his father was a forensic pathologist. When his father was away his mother would leave. Then come home late at night or early in the morning with a random person and they would go to their house basement. Never to be seen again.

Jungkook, on the other hand, would always stay in his room locking himself up. He was always bullied since his parents had weird jobs. Kids always made fun of him. He never knew what his mother did. All he knew was she was busy doing work.

One day his father went home. Stressed and tired, his face clearly shows that he hasn't had enough sleep lately.

Recently he had been assigned in the rumuored elusive cannibal killer case and it had been active for the past few months. It is said to be a very violent and cunning one. But because close to none evidence was found it was hard to catch the culprit.

Which stressed him more since he still hasn't had any clue as to how it could be caught.

The way the criminal did his job was impressive. He never left any traces that could be used as evidence to identify him.

But other than that, the way he precisely cut or sliced the body of his victims was incredible. It wasn't sloppy.

They were eating lunch when he informed his family about the upcoming plans that the department made to catch the killer when his wife accidentally poured her soup all over the table. Causing him to see the cut that was hidden beneath her sleeves.

"What happened to your arm?" Jungkook's dad asked his mom. Looking at her worriedly.

"I-It was just a scratch. I fell on the stairs and I accidentally landed on a nail." She stuttered.

He noticed the tensed state of his wife so he pressed her more.

"When did this happened honey?" He asked her nicely but eyeing her suspiciously.

"Huh? It happened the other day." She gulped.

He knew she was hiding something. He didn't know what it was but he was determined to know the truth behind her lies.

Jungkook, on the other hand, was silently observing his parents. He was watching them interact. His eyes never left them.

His parents despite being busy as always tried everything to make time for him especially his dad. For him, his dad was the best. While his mom wasn't like him but she did care for her son. In her own way.

Sometimes she would just snap and hit him but then after everything she did she'll soothe him as nothing happened. This behavior of her mom was unknown to his father.

Jungkook's mom was a very beautiful yet mysterious woman. They met when his father held an investigation near the museum that she worked from before. She was the one assigned to assist them and they got along really fast.

He learned that she was living alone because her parents left her at a young age. He admired her independence for being on her own. Even her bravery because not every woman would want to do a job like hers.

Everything went fast. It didn't even take a year when they got married. The next thing he knew they bought a house near the forest.

She was a very peculiar person. Everything about her seems strange. But that was what he liked about her.

The following year she gave birth to a beautiful baby boy named Jungkook. After giving birth she started to act strangely. He noticed it and immediately brought her to a specialist.

After a few tests, she was diagnosed with Postpartum Psychosis. A mental illness that was caused after childbirth.

Little did he know that it would also trigger a very dark past. A demon that was hidden beneath the beautiful innocent face of his wife.
