Yandere! Student who is a son of a high ranking official. His family name wasn’t the most powerful, but it was powerful enough. Enough to let him walk through the halls like he owned them. Enough to make others look away.
Yandere! Student who you hated so much despite being a teacher. Not because of personal reasons but because of what he does. Drugs, parties, cheating, harrassment and the worst among all of them---bullying where he almost drived a student to kill themselves.
He was a real piece of work. Yet because of his family status and money, he was able to avoid all of the consequences.
Yandere! Student who alway likes to get under your skin. Attempting to humiliate you in front of the class but you already see right through all of his tricks and you were lucky enough to dodge them.
Yandere! Student who always likes to push your buttons just to get a reaction out from you. Whenever he was successful to do so, he would tease you further, laugh at your face while he calls you "unprofessional".
Yandere! Student who would lay on his king sized bed every night. Smiling like a love-strucked idiot while he would repeat that scene over and over again---where you're looking up at him with those narrowed eyes with murderous intent gleaming behind them and when you're looking down at him like he was some piece of trash that glued their way into your skin.
He always felt so giddy everytime he thought about his lovely professor. He couldn't help the heat that was rising from his face and the desire that's growing underneath his shorts.
You were so cute...
Yandere! Student who would often go to your private office. Looking all helpless and desperate. He would kneel beside your chair rather than to sit on the comfortable seat infront of your desk.
"Professor! Can you please help me with these question?" He would whine. You would pinch the bridge of your nose because you know damn well that he isn't stupid as he looks. Though, you would still help him.
Yandere! Student who tests you in the middle of class. He would rip a piece of paper and write something inappropriate before passing it to the student infront until it finally reaches you. As if they were playing pass the message. No one dared to peek at what he wrote, and to be honest he doesn't really care.
You glared at him and he just smirked while whistling a tune, his friends chuckling. You opened the paper and your glare deepened.
'Are you wearing a pink bra? We can see it right through your dress shirt:P'
It said in neat, clean writing.
You quickly marched infront of his desk and smacked his face. You didn't care anymore. This was too much.
Yandere! Student who shivered the moment your palm touched his skin. You touched him... gosh, you really did touch him. He couldn't help but giggle and look up at you as if you just gave him something he thought he couldn't have.
Yandere! Student who sat in the principal’s office with an unsettling calm, as if nothing had happened. His expression didn’t waver---not even when your report was read aloud. He already knew it wouldn’t matter. You were just a teacher… his teacher.
Yandere! Student who, upon being suspended for a week, reacted with barely contained fury. He demanded answers from his father, questioning why he would allow such a thing. But his father only met him with a cold, unreadable stare before calmly announcing their sudden one week trip to America.
Yandere! Student who found himself more irritated than relieved. One week away meant One week without seeing you. Even a single weekend without you was unbearable---he always found ways to follow you then, unseen, unnoticed. Summer had never been an obstacle either; he enrolled in classes he didn’t need, requested tutoring he didn’t require… all just to stay close.
And now, a week miles away from you? It was suffocating.
But no matter how much resentment simmered within him, he knew better than to defy his father.
Yandere! Student who found no joy in the trip at all. The days blurred together, meaningless without you. Instead, he clung to his phone---flooding you with messages, one after another, desperate for even the smallest response. Every delayed reply felt suffocating. Every short answer made his chest tighten. It drove him to the brink.
Yandere! Student who would sob on his pillow every night while fucking his dick with his fist. He scrolled through endless pictures of you in his gallery.
Oh, how he missed you so much. He missed pleasuring himself in front of your sleeping figure---completely unaware and vulnerable for him to do anything he desires.
Yandere! Student who felt alive again the moment he returned to Korea. By Monday morning, he was already at school---far earlier than necessary---his steps quick, impatient, heading straight for your classroom just to see you again.
But what he walked into made something inside him snap.
You stood by your desk, arms crossed, a genuine smile resting on your lips. A smile he craved---one he wanted directed only at him. And yet…
Someone else was sitting there.
An unfamiliar student occupied the chair in front of you, looking up with bright, eager eyes behind thick lenses, completely absorbed in your presence.
Yandere! Student who didn’t hesitate. The door slammed open as he stepped inside, his gaze sharp, dark, and fixed on the unwanted stranger. The other boy blinked in surprise---before smiling.
That sinister smile.
It mirrored something far too familiar. Something that was supposed to belong only to him.
Then, as if he were nothing, the stranger turned back to you, eyes soft and innocent once more.
“Who are they, professor?” he asked, voice light with curiosity.
Yandere! Student who trembled where he stood, rage coiling tightly in his chest. Who was this transfer student? This intruder? And why were they sitting there---talking to you like they know you more than anyone in this world?
Like they were replacing him.
No.
That wasn’t allowed.
He wouldn’t allow it.
You were his and he was yours.
He will make sure of that.
