I have no idea what the mom's intention is (and imo it's all about money coz she knew Sooha is her leverage over the ML).
For me, given that Sooha's mental health is very unstable, I think this is the best choice in the end. Him having another child and experiencing post pregnancy/delivery psychosis on top of what he currently is suffering is an overkill. In his current state, it is much better for him to just have one child. Sooha's mental state will constantly be with him in this lifetime but with the child and the ML's support, I think he's going to get by throughout his life.
I think the both of you are slightly wrong just because the priorities are a bit mixed up it’s not whether Sooha has more children will make him crazier this all has to do with his mother. This contains spoilers but within 3 more chapters you realize the mother never wanted Sooha to get the help he needed- she choose to have his “placenta” removed and not to have his mental illness treated. She never gives Sooha the attention he needs and deserves — SO this is why Sooha develops his own mental delusions about being in an omega facility etc etc. more then likely she had his placenta removed because the ML’s offspring are more likely to take over the company since the mom isn’t as competent. Also why the mom allowed for the child to be born is more then likely so the MOM could control her grandchild— it’s kinda weird that as his grandmother she is ok with her grandchild thinking the nanny is the mom and doesn’t exactly correct him. Also to even avoid situations like this someone of her stature would have more than one nanny tending to the child so he doesn’t get attached to someone who isn’t actually their parent.
Ok i just want to know why this shitty bastard mom removed sooha's uterus after giving birth?? If she removed that because of afraid new heir (her own grandchild) will take her place and power.. she won the worst mom in history. Or is Sooha had any health problems that need to removes his uterus? So sad they only had one because of his selfish mom did this to them. All because of money... Σ(っ°Д °;)っ
