Maybe Taewan is just a homophobe maybe because he have a secret relationship with the guy with the blue hair( dojin's friend) maybe that's why the blue haired guy knows so much about taewon and avoid any questions relating to taewan. Also, maybe taewan is acting like he's a homophobe maybe because he doesn't want people to know that he's gay.
