Wow. I was satisfied disliking the mother, but then she goes on speed run for being just terrible. I thought she was just stressed and being a bad mom as a result, but it turns out she is a bad mom because she is just terrible.
At this point, Tongtong's mom needs to take a verbal sledgehammer and bring it down on Lin Luxi's mom's thick skull.
Like, just tell her their daughters are going out, you support them no matter what and if she doesn't want to alienate literally everyone in her life (seeing how things are going with her husband) she'd better cut it out with the goddamn homophobia.
