Kick Drum Heart (слэш)

Sena had thought that he had his crush on Shin mostly under control. He figured it would always BE there, but he thought that their time apart while he studied in the US had done SOMETHING there for a while to help him not be completely embarrassing every time he was around Shin. Something to help mature that crush into, you know, an unspoken could-have-been like in his mom's romance novels (which he had definitely never read in a fit of pent-up romantic frustration after coming to terms with the real reason why Shin was always shirtless and handsome in his fantasies), and not the juvenile rabbit-pulsed sweaty-hands'd tongue-tied infatuation that he was familiar with.
He'd thought that, and then second year of university came, and he started failing biology.
