Hua Cheng was a butler, and you were his master

He was a loyal butler like a dog being ordered by his master. He would listen to your orders, clean around the house, which he finds as a literal hobby, and boss around the maids, chef, etc

You were in your study room, while Hua Cheng was yelling at the twink ass chef to make sure he cooks dinner on time

"Ugh, these lazy, incompetent maids. They didn't properly clean the stairs." He says, dusting it off with his white gloves
