Ohh I like this too

Yes exactly! I feel like Shen Jiu never actually convinced himself that he deserved his position, and that might have made him more rigid, he didn't want other people discovering he was an "impostor"

Shen Yuan on the other hand, he wears his face yes, but his hair is always a little messy, some loose strands flying freely around him. His smile is a bit too sincere. His robes always a bit crooked, some splashes of ink managing to get to the hems of his sleeves. He lets the facade slip often.
