That's what I think as well! I think Hyesung really just wanted the best for Byul but is so bad at executing it. He just wanted Byul to have better chances at life than he did when he was younger.
thank you for agreeing with me. it just doesn't sit well with me that everyone doesn't see the bigger picture here and just went on saying hyesung is annoying, though that can be true, we should also consider where he's coming from. even when he has his alpha, he even chooses to keep for himself, i just feel so bad for him. he's probably use to going through everything on his own, you can see that in his poor choices before too and how he's acting now, old habits are hard to break ig :((( hopefully we get a character development
Although I think that he shouldn't have yelled at Byul like that but I just realized how young Hyesung is when he started college. He was abused and neglected when he was younger, add the fact that him having his own insecurities is weighing him down. Though these concerns shouldn't be any justification to how he treated Byul, he's really not a bad parent, he even chose Byul over his friends. We can never be perfect parents, he must've been scared that Byul will lack a lot of things like he does, and lets be real here, Hyesung needs to mature a bit more probably can be contributed to the fact that he never had the luxury of being properly guided by his own parents instead, they left him a lot of issues. :(
