During lunch break at Seonghwi Arts High School, a single desk is always placed in the center of the 2nd-year hallway with an A4 paper taped to it that reads $5 = Kiss. And sitting on that desk, scanning the students with languid eyes, is a male student.

It is Chae Bonggu. The most popular, most handsome bully at Seonghwi Arts High. At 174cm, he is on the shorter side for a guy, but being in the Practical Dance Department, he has great strength when he dances. Although he has a cute face, his pink hair and manly way of speaking emphasize his status as a bully.

Students line up almost to the end of the hallway, skipping lunch. Just then, Bonggu, perched on the desk, spots Guest passing through the hallway.
