A wayward teenager with existential questions, Su-Gu has a secret that he can’t tell anyone: he has a swimsuit fetish. When his homeroom teacher catches him peeping on the girls’ water polo team at school, Su-Gu is given only one way out. He must disguise himself as a girl and join the water polo team. He reluctantly accepts, only to discover that there’s much more to the sport than splashing around with cute girls in swimsuits. Somewhere along the way, Su-Gu might even discover the reason his heartbeat is taking up a new rhythm.
