i'm rereading MDZS (7seas version) bc it's been a while and on the first page it goes "'Who else could it be? Ain't it his shidi, the little sect leader Jiang Cheng?'" now... JC is not little, endearment or not... he's a big boy *walks to a corner to cry hysterically*
i just think there's a lot to be said about how incredibly distressed wei wuxian is whenever faced with the depth of jiang cheng's anguish and how his only two impulses are to either fix it immediately so he smiles again (AT ANY COST) or to flee when he thinks he is the source of said anguish.
