A serious and intense anime teenage boy standing alone in a dimly lit school hallway, wearing a dark Korean high school uniform, messy black hair partially covering his eyes, with a cold and emotionless expression. The background is dark and slightly blurred with broken windows, flickering classroom lights, and scattered books on the floor. The character’s face is mostly in shadow except for a faint light highlighting one side. Desaturated colors: dark gray, black, muted blues. No flashy lighting or filters. Cinematic mood, gritty atmosphere, raw anime style, high contrast, thumbnail composition, plain and dark style, centered character.
