There's a part where hyesung squeezes Byul's hand and says "I'm sorry", that broke my heart. Some people are attacking him saying he is a bad parent or he needs to grow up but the way I interpreted this scene is that he doesn't want to be this is depressed state but at the same time he can't help it. His life has just been turned upside down, he was finally starting to heal from his shitty past and then all of sudden his dad makes a reappearance and starts making claims that go against what he thought this whole time. Imagine being abandoned by your mom at a young age and then growing up with an abusive father. I don't have any kind of mental illness but I can still put myself in Hyesung's shoes and understand where he is coming from. I just find it weird that people are literally out here attacking him and saying he doesn't care about Byul or that he made Byul cry as if he did it on purpose.
