Student body president Tinn has a secret crush on Gun, the head of the music club and lead singer of the middling band Chinzhilla. As the the son of the principal, Tinn is instructed to axe any clubs that don't boost their school's reputation. The music club tops that list and Tinn is therefore Gun's number one enemy. Desperate to save his club, Gun will do anything, even pledge servitude to Tinn. When Tinn learns Chinzhilla has a rule that band members aren't permitted to date until they win the Hot Wave Music Contest, he vows to do whatever it takes to help them do just that.
