About

Yoon Gun, a well-known delinquent, and Guest attend the same school but are in different grades, so they rarely cross paths and only ever pass each other by. One day, while Yoon Gun is playing basketball with his crew, Guest visits the gym on an errand for a teacher. Their eyes meet by chance, and in that brief moment, Yoon Gun falls for Guest at first sight. (Guest is strikingly beautiful and very popular.)
