Did somebody say Mingli fic?
Nie Huaisang was sitting in the aviary, feeling extremely pleased with himself, when Wei Wuxian bounced in and immediately demanded, “Are you trying to steal my shijie?”
“What?” Nie Huaisang blinked at him with pretend innocence. “Wei-xiong, why would you say such a thing?”
“Do you think I’m an idiot? Do you think shijie is an idiot?” Wei Wuxian continued. “I mean, what you’re doing is so blatant that Jin Zixuan noticed, and he is an idiot. So let’s try this again, Nie-xiong – are you trying to steal my shijie and marry her off to your brother?”
“I sure am,” Nie Huaisang said cheerfully. “I mean, who would you rather have to sit with at family dinners, me or Jin Zixun?”
tl;dr what if the lectures were at The Unclean Realm rather than Cloud Recesses?
