there has been so much shen brothers au but where is my shang brothers au where original qinghua is the smarmy bitch who believes his twin is a piece of shit until he notices how capable he is and how intelligent must be to not get manipulated by him and how little he cares about anyone else or tries to because You Know that having a twin that he knows he Will Die Terribly by the plot has changed him for life
truly
original shang qinghua would do a somersault from "my twin has no intelligence" to "i would kill everyone and him included if something corrupts him"
meanwhile airplane would try his best to stay as a npc until he sees how much original sqh would put himself on dangers way to "protect each other" and doing second handed stuff to save him from himself leaves him even more tired than what he should
