Hyesung (Uke) is obviously wrong for using his baby as black mail.
(╯°Д °)╯╧╧BUT at the start Is just trying to find a partner, finds out he is an Omega, has his first heat cycle and sex with a stranger. Almost gets raped by a fat guy, finds out he is being used by Dojin (Seme).
Gets a job and tries to move out, gets ready to leave, gets raped (admit it, he was)
╮( ̄▽ ̄)╭ finds out he is pregnant with a man he doesn't love (yet)ヾ(☆▽☆). I also feel like Hyesung knows he isn't ready to raise a child and because he doesn't love Dojin, that's why he wanted to get rid of it.
╥﹏╥
Yet he respected dojin being a father and respected that partly he was to blame in the pregnancy incident when he told his friend wait , and honestly he is trying to look out for himself from a person who lied to him twice, how can he believe him?
Dojin's intentions are pure but hyesung doesn't see that and he would be a fool to trust strangers especially who lued to him and besides his friend was right , if dojin was just being nice now , hyesung's life would be fucked ...
Besides the past of hyesung is still yet to cleared which shows how brutal was his father .......
People hate on him for whatsoever ...just cuz they love dojin but come on he is reasonable at least and clear ,
He continuously gets stuck in scams. He is ready to sleep his kid for money. He is arrogant as fuck. He is brainless. He totally sucks.
I'm sure the mangaka is planning a big reveal for who Senku's real father & mother is but it could very well be Dr.Xeno. I honestly find it hard to believe but I also can't rule it off. Byakuya said that Senku is "his friend's kid" that could mean coworker, sibling or an actually friend.
