Well some people were arguing how about Kyungjoo? It's also his first time as a parent, but he's being a responsible one. For me, the thing is our man Kyungjoo is already a head of a company so of course he'll be responsible with this matter. Also, I think Wooyoung having a bratty attitude had already prepared him for the worst.

Yes, he's a bad parent for now. You can see that he wanted to have the baby, but he was not prepared yet for the responsibility. Not all expectant mothers are good with their job as a parent as soon as the child is born. And yes, there are people who seem not interested enough to take care of the baby because they have the luxury to do so (just like him: a chaebol, spoiled by his family and lover, young at age). But his behavior with baby Chacha was normal, at least he was composed enough to go to the hospital for his treatment. Give him time and he can be a more responsible mother just like Hyesung.
I don't know why I'm being defensive, but I just hate it when people shit on omegas that don't look like ideal parents as soon as the children were born. Especially they were young when they became pregnant.
