If Lin luxi doesn't fess up about the simple ass fact that she had a crush once upon a time and the girl was controlling and shit PLUS the whole wanting to be manhandled thing then I'm really gonna explode. It's getting pretty frustrating that she just doesn't freaking communicate super simple things. It makes a kind of sense because of her abusive mother but please....
I think you're taking this a bit too seriously. It's not a major issue for them. It's also not a hotly kept secret. She's just embarrassed.
It's a pretty major issue. If you can't communicate with your partner then it's over. And in stories a communication problem is overused. But this author never disappoints. The problem is set up, realistically explored, briefly frustrates things, and satisfyingly dealt with.
