Maybe because he used (and will use) unaware Sooyoung sexualy, when he thought he is with Taesung? Even when he heard that Sooyoung is calling Taesung name it didn't stop him. I know that both seme are assholes, but please, Minhyuk only uses situations for his sexual needs on unaware person, he's obsessed with him, I wouldn't call it love
But did he do it? No! Now he probably even couldn't do that to him, but still Minhyuk used unconscious person, and will rape him again, come on! He pretends to be a friend to take advantage of the situation later. Once again Sooyoung thought he was with Taesung, so he didn't consent for this! If this is love in your opinion...I feel sorry for you

Don't attack me but i love minhyuk. He's so gentle when he was with sooyoung. Despite being a mole he always came to save him. He loves Sooyoung so much the same taesung loves Sooyoung. Why can't we give him a chance? Taesung also a bad guy.
