You and Sehun have been in a relationship for a year and your relationship with him is pretty popular at the school you two have been attending to.

It was 2 years ago, both of you met when you were still new to the school, you were rushing your way to your classroom when you felt yourself impacting someone's chest. He was rude to you, you looked up to him, you could feel his cold eyes staring back at you like knives stabbing onto your body as you immediately apologized.

He rolled his eyes and walk passed you, roughly brushing his shoulders to yours. You knew he was annoyed and you didn't want to give someone a bad impression on your first day.

On the next day, you tried to find him during lunchtime when you came across a hallway, you then noticed him being surrounded by a group of men at the distance. You froze at your spot but immediately went to the corner to hide and peek at what they're doing.

Your eyes widened when the group of people starting attacking him, this was bad, you could hear the sounds of grunting and groaning while you were there hiding in the corner, your hands cupped to your mouth to prevent noises.

You never felt so panicked in your entire life when Your phone then started ringing, the men at the distance were alarmed by the irritating sound of a phone call. "Who's there? Come out!" One of the men spins around to look around if someone was witnessing the scene.

You didn't have a choice but to show yourself, your body trembling at the sight of them dangerously staring at your figure. They eyed you for a couple of seconds before one of them walks up to you and grabs a handful of your hair, yanking it roughy as you shrieked at the sudden action. You whimpered, clasping your hands on the man's wrist and struggled out of his grip on your hair.

"Looks like someone's worried," One of them snickered, watching another man walking in your direction. He smirks at your state, you were inches apart from the guy when his hands made its way to your face, squeezing both of your cheeks with only one hand.

"Is this your girlfriend, Sehun?" He smirks. Sehun only glared at him, fist-clenching tightly as he watched you struggling with the tears streaming down to your cheeks before he grabs the arm of a student if holding him in place, twisting it as he pushed him to the ground, earning a loud grunt escaped the student's lips.

He then kicks the students who were now charging at him, he was so relentless, taking down the students so they could start to run away from him. He turns to gaze at your direction and jolts his way to you, pulling the guy in front of you away and punching the other one who was holding you in the face.

"Stop!" You pulled onto the jacket he was wearing while he punched the man too many times although he was already knocked out from all the beating. "Stop! You could kill him!" You cried out. He eventually stops and looks at your eyes filled with panic and fear. He then grabs your arm as he pulled you to somewhere where the two of you could hide.

His eyes then averted to you, "What the hell were you doing there? Do you want to get beaten?" He fired at you which made you fidget your fingers and avoided his eyes but you felt his hand grabbing onto your chin as he shifts it up for you to look at him.

You then felt your cheeks heating up, your heart was beating so fast when he moves closer to you, not breaking the eye contact.

You then felt a lump in your throat. "S-Sehun?" You called out to him as he snaps and moves away from you, he then looks out to see if the students were still there and gaze back to you, "You're lucky I saved you even though we barely met. You should be careful sometimes on what you are encountering."

He stands up and reaches a hand out for you stand as well. You grabbed onto his hand, pulling yourself up to stand, "You should go and attend your class."

You nodded, you were about to turn around and leave him, however, Sehun grabbed your wrist which made you gaze at his direction again. "Meet me tomorrow at the rooftop."

You wanted to ask why he wanted to meet you but he already left you there alone. Your heart pounding so rapidly after the whole thing that happened on the 2nd day of attending school.

You came back to your classroom with the students and the professor already inside. The professor stopped talking and turns to look at you with her hands placed on her hips. "May I have the reason why you are late today?"

You looked down, fingers fiddling and answered, "I got lost on my way here," She sighs and points at a vacant chair at the back. "Alright, but don't do it again or I'll tell this to your advisor for being late on the 2nd day." You nodded at her statement as you walked to the back and sat on the vacant seat.

The next day, it was boring as usual when the sound of a bell had rung. Students pack up their valuables and left the classroom without making noise while you quickly shoved your things to your bag and ran outside the room. You ran towards the stairs that lead to the rooftop, opening both doors to be greeted by the strong wind and beautiful blue sky. You scanned everywhere to search where the tall guy—or Sehun is until a voice was calling you.

"Looking for me?" Your eyes widened and look behind you to see him, his hands on his pockets, the first and second buttons on his uniform were unbuttoned and his bangs were hiding some part of his forehead.

His lips curved to form a smile making you smile back, eyes brightening up when he takes your hand, and walked to the other side of the rooftop to watch the beautiful scenery.

And so you would meet him every day at the rooftop to hangout. He was the only guy you could trust, and he was the person that protects what matters to him against the other people who tried to pull you down.

Students were astonished by the friendship you had, others tell you to stay away from him, others say he couldn't be trusted but you brushed them off, thinking that were only trying to threaten you.

Some girls warned you to stay away from their Sehun, but Sehun said to ignore them because they were just jealous. It was like a typical story where the girl antagonist tells the main girl to stay away from the lover, what a deja vu.

You spending time with him went for years until the day came, he had called you to meet with him somewhere, you asked him if there were any special occasions he told you it would a secret, plus, he wanted to see your reaction.

You arrived at the school garden where Sehun told you to meet him. You eventually found him standing beside the school's fountain, the water continuously running down the basin. You cleared your throat to get his attention as he turns around to see you standing in front of him. "So why do you want me to come here—"

A surprised expression left your face when his slim fingers trailed to cup your neck, his face leaning to yours, capturing a kiss from your lips. You couldn't believe he was kissing you right here, right now. You didn't hesitate to give in, clutching onto the jacket he was wearing. When the kiss didn't last long, he panted, resting his forehead against yours. "I like you."

"Well you could've confessed first before kissing me out of the blue." You chuckled, widely smiling at him, giving him a light smack on his arm.

You've been dating for the whole school years, but in those relationships you promised each other not to hide anything and not to be involved in any school fights. While your relationship with Sehun kept on going, the students around you start to notice. Although you don't like the sound of getting the attention, you just stayed quiet.

You placed your books in your locker, and as you were about to close it, some of the girls in school walked up to you as if you were some sort a celebrity standing on the corner, "I heard about your relationship with Oh Sehun, oh you're so lucky to be with him!" One of them exclaims.

"I know right, you two are a perfect couple!" The other squeals, looking like they were admiring a role-model. You nervously chuckled while rubbing your nape, "Thank you," You gave them a soft smile before walking away.

While walking by the hallways that were occupied by a lot of students, you could hear the chatters from every corner of the hall, you looked to a group of students laughing and sharing stories, you sighed, it would be nice if you were to have a friend, but Sehun was the only one you could trust for all your high school years.

Before you could even leave the hall and enter your next class, you then felt a sudden smack impacting to your ass as you gasp in surprise, cheeks turning red. Your eyes widened and immediately turned around to see a guy, plastering a weird at to you, "My my my, no wonder the Oh Sehun made you his girlfriend, you're quite pretty than I have expected to be since the last time we met."

Shit, it was the guy you encountered in the hallway years ago when you met Sehun.

He slithers his hands to your waist, you bit your lip, trying to keep a straight face as you moved away from the guy. "Please leave me alone," you muttered, you could feel the other students eyeing the two of you, he then chuckled as he grabbed your wrists tightly, "What about leave Oh Sehun and be with me—"

"Let go of her this instant,"

Your eyes widened when your boyfriend abruptly pushed the guy away from you as the guy stumbled on the floor, eyes dangerously glaring at the guy. You knew he was about to beat him up. "How dare you fucking lay your hands on her." he was about to punch him but you grabbed his arm and looked at him, your eyes begging him to not make a scene.

His cold eyes stare at you before turning to the guy, "You will pay for this." He says before he was being pulled to the other hallways by you. You folded your arms, placing them against your chest. "I'm begging you to stop getting involve in fights, Sehun." You started, all he did was to look down to the floor with his fist clenching hardly.

"It's better to just confront them, I don't care if you threaten them or curse at them but please, No fighting." You reminded him once again. He finally looks up to stare at your eyes, his hands carefully placed on your shoulders, pulling you to him. "But I need to show them that you're off-limits, who wouldn't be furious of a guy who just inappropriately touched you?"

You pulled him away, swallowing hard as you turn around. "Just like I said, confront them, don't fight them." You said, leaving him in the echoing hallways alone.

It was about a week later, another boring weekday not until you heard about students gossiping around the campus, their eyes were quivering with fear as if the atmosphere had dropped to the lowest point in school. You were curious about what they're talking about so you grabbed the courage to went up to some students and asked, "Is there something I don't know about?"

You gulped, you could tell that they saw something horrible, just watching their legs shake as they glance around the hallways. One of the students eventually responds, "Donghwa, he was murdered. We saw him laying on the alley with his chest ripped open, his eyes fell out from his eye sockets and—Argh I can't! The gore and blood just make me nauseous." She says, tugging on her locks while shaking her head in fear.

Donghwa, you've seen that name before. Was he the guy who he was almost git beaten up by your boyfriend? Your eyes widening at the realization, did something happened between them? No, you shook your head. Sehun won't do such a thing, he can't kill a person.

You went to search for Sehun around the campus to ask if knows anything that happened to the guy who inappropriately touched you the other week. You stopped when you found him roaming around the hallways before bolted to his figure. "Sehun, can I ask something?" He turns to gaze at you, shoving his hands inside the pockets of his jacket and raised an eyebrow.

"I was wondering if knew about Donghwa's death—"

"What? He died?" He only said, eyebrows raising in confusion. You wanted to tell more but looking at his confused look made you sigh, averting your eyes from your boyfriend. "People are talking about Donghwa's death, do you know anything about what happened?"

"I have no idea what happened," He answers shortly, rubbing the back of his neck. "I was at home doing my business." You raised an eyebrow at him, putting your hands on your hips. "And what business were you focusing on?" He laughs at your question and just ruffles your hair to mess it before taking your hand in his to start walking towards your destined classroom.

"My motorcycle broke so I had to fix it for the whole weekend." He explains. When both of you arrived at your classroom, he places his hand on your back and gently pushed you inside. "We'll talk later, Y/N." You saw him plastering a grin, leaving the hallways alone.

The following days, numerous people would start to bother or annoy you. Men would start to hit on you and forced you to leave Sehun, however, those people in the following weeks would get injured, go missing or killed. People would talk about it around campus except for your boyfriend who has no idea what happened to them. He was never been updated by the news and it's bothering you.

What if he was lying to you all the time? What if he knew what happened to those people. Those questions lingered around your mind and you wanted to know the truth, even if it means fighting or arguing with Sehun, you couldn't take it anymore.

It was on the weekend when you stomped your way to your boyfriend's apartment. You aggressively opened your bag to find the key to his apartment as you took it out from your bag, pushing the key to the hole of the knob. You didn't even think twice but to step inside of your boyfriend's apartment as you were greeted with a weird stench making you scrunch your nose.

"Oh Sehun! where are you?" your voice boomed, echoing in the darkroom. You looked around and clicked your tongue, closing the door as you threw your bag to the couch.

The apartment was quiet, very quiet. you were getting irritated as you began to search him around his apartment, you looked at the kitchen but there was no sign of him. You then stared at his bedroom door, just looking at his door made your heartbeat pound inside your chest.

You took small little steps towards the door, the echoing footsteps were making you tremble a bit. You were greeted with a strong scent of a perfume that he always used once you were inside the room, almost making you dizzy. The room was completely dim but the only thing that brightened a part of the room was the lamp on the nightstand, flickering.

You decided to check around his room, it was neat as usual when you always visit Sehun, however, you were told to never touch any of his things. And now you're going to search for anything that'll solve anything from the problem that always lingered around your mind. You walked over to the nightstand and pulled the drawers, and you gasp, stumbling down the floor.

You couldn't believe your eyes, it was pictures—pictures of the people who harassed you, annoyed you, hit on you looking distorted and badly injured on the photos. You covered your mouth to prevent from gasping. You felt nauseous, you wanted to throw up seeing the pictures displayed on the drawers.

"Y/N?" Your heart drops, hearing that sickening voice calling out to you. You turned around to see him there, staring at you with that faceless expression. You tried to stand up but your muscles won't budge by just seeing Sehun in front of you.

"No, don't you dare take another damn step!" You screamed, watching him stepping back to his place. "You lied. You lied about everything, You were the one behind this, all of this, you did those horrible things to those students."

"How could you? I thought you changed, I thought you've become the Sehun I knew, but it seems like you pretend to be a goody-two-shoes in front of me." You continued to spat at him. He then plastered a smile as he watches you tremble in fear. The smile on his face was creeping you out, and shivers lingered down to your spine, you couldn't see the same Sehun anymore. "Well," He grinned, slowly taking a step towards you.

The hot substance streamed down your cheeks, feeling Sehun's grip on your neck as be pulls you up to meet his dark gaze. "They were hurting what's mine, they were bugging what's mine, they were touching what's mine, they were taking what's mine." Every emphasized word made his grip on your neck tighter, starting to strangle you unconsciously.

You choked out, "S-Sehun." He giggles, his other hand reached out to caress your wet face. "I did it for you, Y/N. I had to prevent them from interacting with you, so I stopped them."

"You didn't stop them, you hurt them to the inch of their lives." You corrected him which he let out a deep chuckle. He then leaned over to place his lips over your temple while you cringed at the sickening feeling. "Don't worry dearest, I always protect you from harm, even it cost their lives."

"You monster." You snarled, trying to struggle out of his grip with your hands pulling his hand away from your neck. "Oh," He sighs,

"You have no idea what I truly am, dearest."
