Yiseo has a problem. Is the problem that he’s a closeted gay college student? No. Is it the fact that the hot upperclassman he has a crush on seems to find gay relationships uncomfortable? Sorta heartbreaking, but still no. Is it the fact that Yiseo has been invited to live with said crush, Seonwu? Almost, but no. The problem is that Seonwu wants Yiseo to teach him how to have sex with a man, because he’s in love with one. So what is the solution here? ...Start a semi-educational friends-with-benefits relationship with his crush, obviously.
