Wouldn't It Be Nice

Hyobin and Gichan have been best friends for a decade, so Hyobin naturally thought he knew everything about Gichan. He always knew that Gichan was sweet and gentle and super dependable. But when he witnesses Gichan kissing another guy, Hyobin realizes that he doesn't know his best friend as well as he thought. In fact, he somehow completely missed the fact that he's Gichan's first (and current) crush. Now, it's up to Hyobin to make a move and figure out whether this friendship is going to tank entirely or get a hell of an upgrade.
