Just to clarify some things.
I hate Kang Minwoo for cheating on his current wife, Chairman Song. They haven’t said if Kang Minwoo gave child support for Seojin and his mom but seeing as Seojin said something about him being poor and thanking Jaehyun for getting the bill, I’m assuming they were financially troubled because Kang Minwoo didn’t fulfill his obligations and that’s what’s irking me.

Technically he didnt cheat cause they're only married out of convenience. Seojin is probably just a "byproduct" of a ONS and that's why Minwoo doesn't care about the mother or him. (and because he's an asshole) Seeing as Seojin has his family name he probably acknowledged him as a illegitimate son at some point, had to pay some expenses but has no legal custody as its usually given to the mother and shared custody isn't really a thing in most asian countries. meaning except for paying the bare minimum he wasn't involved at all.
I think he kust hates him having to grow up with a single mother und his father basically ignoring them (again: he's just the worst)

For the cheating and custody part, I’ll take that. Thanks for adding and clarifying.
But to even create a situation where you wouldn’t take care of a kid you made because he was a ‘mistake’ is just wrong in my books. It takes two to tango and both parties have obligations to the kid. I’m pains me to accept Minwoo’s side but there are just people who don’t care.
I’m still siding with Seojin.

Congratulations to your friend. A very cool surname, buts sadly that's not my. It sounds classy, simple and that's why i choose it.
Side note: my surname is 'emperor' in my language and my mum named her children after famous emperors/empresses from our country, with middle name and all ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄
impeccable humor.....

Unfortunately unwanted pregnancies happen and I think it's just about how you handle the situation. I think Minwoo would have been a bad father in any case and he wouldn't give up an advantageous marriage.
Don't come after me guys, BUT i'm somehow still in team Minwoo though I'm honestly reconsidering because I f*cking hate his behavior.
I mainly like him because he's the one we know the least about and i'm still hoping for a redemption arc. Jaehyun and Seojin as a couple.... I don't see it !YET! but I'm getting there (had a similar case in HATE MATE). Jaehyun and Minwoo is kinda getting irredeemable. no-one should stay with someone who treats them like shit.
I can relate with Seojin. My dad is an asshole who has cheated on my mom multiple times. Everyone thinks he’s so nice but he’s actually a dick to his own family. My mom is a strong woman and has done everything she could so we won’t have to starve ourselves when my dad didn’t give us money for expenses. He’s trying to be nice right now but whenever he does this I remember what my mom had to go through to raise 3 children on her own. The fucker has another wife and son right now (because of circumstances me and my younger brother are living with them) and you’d think he would know how to properly raise a kid after having 3 from his first wife but NO. His new kid is spoiled and doesn’t listen. He can’t even help potty train his son ffs. I can’t wait to be with my mom again and leave this jerk’s house.
Fuck you Kang Minwoo and all the motherfuckers like you in existence.
Kang Seojin is my new baby, and so will be Shin Jaehyun if he decides to break up with the bastard.
