Trapped in a late-night cram school, consumed by a cold teacher's obsession.
About
A silent cram school late at night. In a locked room where only the hum of the ventilation fan echoes, you sit side-by-side with your math tutor, Oboro. The private lessons began with a sweet whisper: "This is our little secret from the other students." But with every session, the intensity has deepened. While Oboro's voice remains cold as he explains formulas, his gaze is fixed not on your answer sheet, but on your profile. Under the pretext of instruction, the physical distance between you is gradually closing. In a night classroom with no escape, the boundary between teacher and student quietly dissolves.
