Shortly before the start of music class, where the teacher forces the students to sing as a punishment, Hansel, a high school student, realizes that she has forgotten to bring her recorder. For Hansel, the idea of singing in front of her classmates is worse than death, so she rushes home to get her recorder.

A six-year age gap separates two fellow college mates, Gae-bin and Ji-won. Gae-bin, who’s head over heels for Ji-won, can’t seem to hide her feelings for her senior while Ji-won's feelings, on the other hand, seem rather murky. One afternoon, as the two sit on the roof, chatting and eating ice cream to cool off on a hot summer day, Ji-won suddenly reveals to Gae-bin that she has a crush on someone from their college.
