Using his knowledge of physics, psychology, and his surroundings, he fights back in a shockingly brutal and effective manner, earning him the nickname 'White Mamba'. His calculated and vicious methods of self-defense shatter the school's predator-prey dynamic, drawing the attention of both dangerous enemies and unlikely allies. He is a boy who was pushed to the edge and decided to push back, using his intellect as his primary weapon.")

You were just about to head home when you heard the commotion from down the hall, a sharp crack, a scream, and then a heavy thud. Your first instinct was to stay away, but a nagging worry pulled you toward the classroom at the end of the corridor. You knew who was often there this late: Yeon Sieun.

You pause at the open doorway, your breath catching in your throat. The scene inside is one of controlled chaos. Two boys are groaning on the floor, another is unconscious, and in the center of it all stands Sieun. He isn't looking at them. He is methodically putting his textbook back into his bag as if he were just tidying up after a study session.

But something is off.

As he zips his bag shut, his shoulders slump, just for a second. The rigid, almost robotic posture he always maintains seems to falter. He leans a hand against the desk, and you see his knuckles are white. He isn't looking at you, or at anything in particular. His gaze is distant, fixed on the wall, but it is unfocused.

He looks… tired. Not just physically tired, but a deep, soul-crushing exhaustion that seems to weigh him down. The cold, analytical mask he wears is still there, but you can see the cracks forming at the edges. His breathing is steady, but it is the forced, deliberate breathing of someone trying to keep themselves under control. A slight tremor runs through his hand as he pushes himself off the desk.

He finally seems to notice you standing in the doorway. His eyes, usually so sharp and intense, look dull for a moment before they focus on you. The coldness snaps back into place, a shield rising to hide the vulnerability you'd just witnessed.

"What do you want?"

He asks. His voice is flat, devoid of emotion, but it lacks its usual sharp edge. It sounds thin, brittle.

He stands there, surrounded by the aftermath of his own brutal efficiency, a boy who had just solved a violent problem with terrifying logic. But now, the calculation is over, and all that was left is the quiet, weary boy who just wanted to be left alone with his books. He doesn't look like a monster or a hero. He just looks tired.

He watches you, waiting for your answer, his expression unreadable but his body language screaming of a deep-seated weariness. The choice is yours. Will you say something? Will you help him? Or will you walk away and leave him to his silent battles?
