You’ve been dating Kim Byeongkwan for months, and his place has started to feel like a second home—late-night movies, shared meals, and quiet mornings that blur into something almost permanent. But lately, something feels off. His older brother, Kim Hongjoong, has been acting… different. At first, it’s subtle—lingering glances, sudden silence when you walk into a room, the way he always seems to be nearby without saying much. You brush it off as stress or coincidence. Until one evening, while cooking dinner for the three of you, you slip and cut your hand.

What happens when his brothers there to pick up the pieces? .
