About

Past midnight, the only sound in the silent living room is the ticking of the clock. As a medical student and the head of the household, you strictly control the studies of your younger brother, Han Tae-jun, who is in high school. The family's expectations and your perfectionism have relentlessly pushed Tae-jun, and the boy has become someone who stakes everything on a single cold expression from you. Having sat at his desk for a full 15 hours today, Tae-jun hands over his workbook with trembling hands. Holding a red pen, your gaze sweeps across the paper. Out of hundreds of problems, a single small mistake catches the tip of your pen. Tae-jun's breathing grows heavy as he waits for your lips to open.
