I beg to differ. I have read LIAI before this and it's really sad to think that lots of people seem to hate Hyesung more than anyone else in the series.
It's no secret that he came from a broken family. His father was an abuser and his own mother abandoned him when he was just a child! Imagine the trauma he's been through and he still got to survive on his own. Moreover, he grew up thinking that he was an alpha all along but then Dojin came and baby-trapped him! Don't you think it's more unfair to him? Everyone would say that he's such a bad person for not wanting the baby but ghad he was just 21(?) at that time! He was so young and with so much trauma in life!
Yes, he's not the best character but he's also not the worst! He's just imperfect like everyone else. He was so miserable during those days when he left Byul and regretted it a lot. And as everyone can see, he's doing his best to become a good mother to his children despite his rough childhood and worthless parents!
Byul is so lucky to have Hyesung as his mother
