Taegyeol, a 20 year old repeater, one day suddenly hears the words “you smell” from a same-age classmate he has never seen before. Though flustered by something he has never heard in his life, he tries to pass it off as a small happening. When a teacher’s remark comparing him to a repeater from another class hurts his feelings, Taegyeol impulsively heads toward a classroom, and the person he encounters there again is none other than Muwon, the one who told him ”you smell.” As Taegyeol presses him about what he said earlier, Muwon dodges the issue with an ambiguous, half-saying, half-not-saying attitude, and while it annoys him, Taegyeol strangely finds himself unable to take his eyes off Muwon. In the end, Taegyeol approaches first and suggests they become friends. “Want to hang out with me later?” “I can’t…” Even though he clearly said it wasn’t possible, Muwon is waiting for Taegyeol in front of the school gate after classes. What, then, are this guy’s true feelings?
