This situation looks so horribly bad for Haneul to the point it's just plain funny, he went on a blind date while already having a boyfriend and stayed to the end of the date, let himself be guilt triped into having dinner too, and when confronted about it he responds like his cheater mom and asks to break up, I don't think Dajeong is emotionally mature like other readers think, I'm sure he's just like, thirsty for Haneul, like obsessed with him, so of course he's willing to sit down and talk it out, he finally has Haneul right where he wants him.
Haneul needs therapy is my verdict
