Yukiko has terrible taste. Konomi is still best girl.
you muat really love manipulative people if you think that jackass is anything worth loving given her twisted inflated ego and manipulation, no one on earth should be in an relationship with konomi
Honestly, this doesn't really deserve a response but I'll give you one anyway.
I'm not going to pretend that Konomi hasn't done some manipulative stuff, but overall Konomi has been really upfront about what she wants from Yukiko. Yukiko is the one that has been giving everyone mixed signals, but Konomi has been going for what she wants in the way she thought was best. She's a girl that's suffered some trauma growing up, and that's messed up her sense of what is right, but that doesn't mean she is actively malicious.
Fuuko, on the other hand, has been so toxically jealous that this chapter was the first chapter since like chapter 4 or 5 she actually said Konomi's name. She just kept calling her "that girl" which in no way implies she would be a person ready for a healthy relationship. And unlike Konomi, she has no excuse.
Not to mention, as all best girls, Konomi has been the only one to actually move the plot forward. Before Konomi, Yukiko and Fuu were not in a relationship, they were just friends holding hands.
