Yoojin is bad boyfriend material. It's partially because he never takes anything seriously, but it's also because he's never had a great time in bed with anyone. After being publicly dumped, he's approached by Hyeonsoo, an old high school classmate who also happens to be Yoojin's first love. After a round of drinks, they spend a heated night together that might have been a great time, but Yoojin remembers none of it. Torn between denial and desire, Yoojin has to decide whether he's serious about Hyeonsoo... which would be a lot easier if they could ever have a proper conversation.
