Ok when I read the comment about everyone hate hyesung be like ヽ(`Д´)ノ
Hyesung grow up in broken family and he get pregnant at young age. When he leave byul with dojin because first he scare and don't forget Hesoo also hide him. He a not even ready to have child. Hyesung marry dojin because he want byul can grow up in good parents relationship like dojin parents, he even cry went he don't take good care of his own child and say why he ran away that time. Hyesung do many think just for byul. Hesoo also bring byul to see his own mother in weak mind state. Hyesung don't want to see byul that time his father see him and collapse because he afraid he will lashes at byul or hurt byul because his mind state he say sorry to byul because byul saw him in he weakness state.
Have you thought if you in hyesung place you talk like that because you don't put yourself in hyesung shoes and live with hope expectation to be a alpha and learn that your are omega. Yes he ran away but he can run away to another country without care about byul been loved or abandoned but he ask hesoo that how byul and when to see him just to know byul been loved
Many people comment about yu personality but I have opinion about yu personality. In early chapter, yu act like teenager who hate vampire and like some typical shounen mc. But i notice how he childish personality or his child like personality is same like when he is angel mika. It's like a clue, his personality change more like child like when he defeats the three demon and claim mika as his. It's like some part his humanity gone and his true personality come out
Yu is unique to me because how complicated his personality and behavior. Like recent chapter when yu say he want bring human and angels is show what he belief and what is good for him.
I don't hate shinoa and some don't understand why she act like that. Yu show her how he wants be heroes and save his family. Shinoa is influenced by that and think save yu is good act.
