Mingyu is actually incredibly fond of Xingchen on grounds of being trusted immediately, knowing he himself is a terrible person, and being like oh god you're stupid. He once used Xingchen as an alibi during a bank robbery. (Don't worry he was safe, we just took him shopping and held his hand.)

Also Jiang Cheng is like post time skip but probably only distantly remembers Xue Yang as the guy who out-bottomed his brother once at Yueyang. "Aren't you that guy who was so shameless it taught Wei Wuxian the meaning of shame?"

I am climbing slowly back on the RP horse, which of my sons would you like and where.
