Byul darling, that's called jealousy. Siwoo’s gentleness shows in how he listened to Byul's ex rant instead of ditching her, even though he obviously has zero interest in her
Or ignore it like the question was never asked. At this point, we can only hope that byul realises it by himself. Dunno how many light years it's gonna take.
ugh its always the "but he's really a good person" after all the shit :///
