Be Still My Heart

A wayward teenager with existential questions, Sugu 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, Sugu 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, Sugu might even discover the reason his heartbeat is taking up a new rhythm.

Can Sugu find something to get out of the standstill his life has come to? Can his heart beat again?
