Luo Cheng basically started this state when he was with Qin Qiong.
Luo Cheng: Cousin, I am the most obedient! My favorite cousin! My cousin is right! Wherever my cousin goes, I go! Cousin, please be gentle and please touch your head!
Qin Qiong: Be good, be obedient, don't blow your hair, and don't mess around.
