It's bad.. Uke assumed that seme don't want kids?... Because of that idiot uke, 2 kids didn't have loving father (which clearly would've gotten if uke confronted seme)... And the father wasn't able to enjoy his kids initial years and uke's pregnancy... Only the story to conclude everything in few panels. I can say it was poorly written story.

Yes MC asking ML to leave the 2nd part was necessary. Being a partner with a sex worker requires a lot of trust and communication but I don't think ML is doing what's necessary to keep their relationship healthy. We know he doesn't need money and doesn't care about sex so why is he still doing the sexual work. If there is a reason why can't ML share it to MC, he cuts of the MC and hides things, it's obvious that MC will grow insecure.
Moreover, if he can't share the reason why not take a break from relationship to focus on your mental health and try to trust the person you love. If ML wants a normal healthy relationship he needs to do something. He won't even breakup with MC.
As for the 2nd couple... I think the lil brother should leave and move on. Myung dont deserve lil bro
I'm regretting now
