you're right, it's not easy to get pregnant when you're not ready for it, it' can be quite scary in fact and post partum depression is not a myth.
Also, mother rejecting their new born even in a wanted pregnancy is also something that is acknowledge as deserving help and support nowadays. It is not that rare, and it needs a lot of love and care for everyone to find their happiness. It is not something these mothers want, and they already blame themselves a lot.
We are complicated animals.
The character has a lot of circumstances, he probably does his best with his difficult circumstances, lack of self estime/ confidence
tha amount of hate for hyesung tells so much about the intelligence of this community tbh. im also gonna get a lot of hate for this as well but meh
most of you are probably girls yet you lack empathy for someone who is FORCED into an unwanted pregnancy, at a young age. because dojin is so hot and how can hyesung not want his baby what a terrible mother. idk imagine dojin being an average looking guy with an average personality or something. and imagine that you're the one in hyesung's situation. not everyone absolutely fancies the idea of being a mother at that age. some people don't like babies. idk, grow the fuck up maybe.
he is obviously traumatized by so many things and there is an explanation for his behavior. he JUST recently had to accept the fact that he is an omega, after living his whole life living as an "alpha", a proud one at that. and then he finds out he is not, and soon after he is fucking pregnant. he doesn't like the father, or hasn't realized that he might like him, he is new to all this and he justs wants to nope the fuck out and that doesn't make him an asshole. everyone deals with things differently, just because he isn't an absolute sweetheart doesn't mean he is a bad person. it has just been revealed that he didn't even take the money, we don't know why he left yet, we don't know what happened so chill the fuck out please thanks bye
