From what I understand Mi-ok was projecting. She was projecting her feelings of loneliness onto Kwon an Ho's relationship instead of fixing her own problems. Basically her thought process was:
I'm lonely > Mr. Kwon is pursuing a queer relationship > Queerness is not "normal" in the countryside so he might feel ostracised (Like how not having a close relationship with your parent isnt "normal" in college) > I'll set him up with women and fix his problem (cuz I don't know how to fix my own) and hopefully he won't feel so lonely
It's a very childish way of thinking and it's definitely nonsensical to the average person but in her defence she's still a young adult and this isn't too big of a mistake so she can still learn from it and improve.
i still cant make sense of what mi-ok was saying?? like whats the connection of her being a lonely child in a broken family to mr kwon and ho’s relationship? shouldnt she be happy that mr kwon isnt alone anymore? like sure same sex relationships are hard, but thats none of her damn business. can anyone explain her pov or what her thought process was? cos it feels so random and irrelevant to the story hahaha
