Oh i hope not. Cos it really hurts but I believe he's more like jealous of Yuwon and Dojin's relationship. Of how they can still go on. Seems like his jealousy has something to do with his past and the mentioned "Heewon hyung" or he has feelings for someone but can't push it considering of what happened with this "Heewon hyung" and he's the leader of their group.
wait does the purple dude lyks dojin? or is it yuwon? or is he jealous bcoz he has someone he lyks but cant be in a relationship due to his career?
