no most of us just hate cheaters, even if it's yaoi, it irks me so so much if the uke cheats with their previous lover with the seme. hell, even with straight couple. don't be in a relationship if you're just going to hurt your lover.
She isn't cheating! She agreed to be in a fake relationship in order to protect the person she's in a real relationship with. She can't cheat on Yuna, because they aren't actually dating, and she isn't cheating on the prof because she isn't actually dating Yuna, and because honestly I get the impression that the prof has basically dumped her in her own mind anyway.
They wouldn't. People shit on feminine guys in yaoi all the time. It's people being heteronormative and shitting on ANYONE who doesn't fit into that standard. It's homophobia both ways.
y’all are starting to act a little lesbophobic with how you treat min suh.... because i bet if this was a yaoi story with a feminine guy and a masculine dude, you bitches wouldn’t be saying half the shit you’re saying.
