Ok, maybe she's just testing him, blah, blah, blah... But her stance seems so strange? Like on one hand she's ok with them being together, but on the other, wants her son to get married?? Maybe that's some rich people shit, but it don't make sense. Like how have you ccepted that your son is gay, but still expect him to "settle down" with a woman?
I feel either she's poorly written, I'm dumb and don't understand, or she's testing him.

there are parents like that sadly. they're fine with you having to experience "it" and them thinking "it's just a phase" but by the end of the day you have to give them grandchildren for just random selfish reasons OR to not end the family tree or something (well lol not this deep but i hope you get the gist)
now that MC said that it will never happen she changes her stance she doesnt like them dating anymore cause "what she wanted in the end won't even happen so why even approve of it?"

While I like the characters, their relationship developement is frustrating. Mr. Yoo clearly has some baggage he needs to process, and at this point theyre just developing an unhealthy relationship. They're a perfect example of why mutually liking each other isn't enough for a relationship. They want/need different things, and don't have open communication (esp Mr. Yoo)

They separate for a couple years while the seme graduates college and becomes financially independent from his parents. At the same time, the omega raises his baby and doesn't tell him anything about his "father". Then the comes back and reconnects with the omega and his kid. It would take some time to build back trust/communication, but eventually they'd re-form they're family. Then the seme would take them to live with him happily ever after.
I can't imagine that he'd disappear forever when he was willing to raise someone else's baby. He knew where the omega went, so he easily could've found him.
When will the plot move forward ...
