it's actually exactly how abusive partners act. first they hit you and then they act all sweet, apologize and say it will never happen again so you decide to stay because you believe that he will change for you (you still love him - or at least think that you love him). but at the end the situation always repeats.
i don't like his girlfriend -_- i mean i don't like the fact that she is weak. both of Seth's parents were strong and they could support each other, his dad didn't have to worry that someone can kidnap his wife and use her as a hostage or something... seth also needs someone who can protect herself :/ i don't want to say that i like that highschool girl who came before to kill him (because i don't) but at least she is strong (and training to be stronger)
to everyone that is comparing it to solo leveling: thas it really matter if it's similar? if you like solo leveling then you know that we are going to wait a loooong time for season 2 so I will gladly welcome anything good in a meantime and that one defenitely looks good
