spoiler : he doesn't
after all the flashback and etc explaining their past ... the chapter when they are back the present he is just in selfpity in his apartment and the bottom is the one to go talk things out ... the VICTIM had to go make an effort to patch things up with him instead of him groveling and begging for forgiveness.
the top is such a loser, he couldn't even go after the bottom to apologize and was instead wallowing himself in selfguiltypity
So he decided to stay away from Mc after what he did? I don't see anything wrong with that
Dude it passed just one day, that he stayed hurled at his house, i don't know if that really counts as staying away.
When bottom went to talk he sure didn't apologize ... If he begged for bottom forgiveness it would have been better ...
Yh, seme is a pice of shit... but compared to the semes in other manhwas he ain't that bad. He didn't rape him, and his anger stemed from a "misunderstanding". His mind was probably clouded with what he heard n he probably thought uke was really a slut. So If uke ends up with him, I don't mind. He just needs to Apologize from the bottom of his heart and grovel at Mc s feet.
