"I'm feeling a bit hungry, could you fetch me a piece of cake?"
"Certainly." The servant naturally knew her identity and how much the young master valued her, they dared not disobey her orders.
Having said this, An Ruo walked into her bedroom. The servant went downstairs, placed a piece of cake on a plate, brought it upstairs, knocked on the door, handed it to her, and then continued to clean.
An Ruo dumped the cake into the toilet, flushed it, waited a few minutes, then walked out and handed the plate to the servant.
"Take the plate downstairs."
What she said was law; the servant took the plate, ready to head downstairs. In her presence, An Ruo walked into her bedroom and shut the door.
Once the servant was downstairs, she quietly stepped out of the bedroom, pulled the door shut, slipped into the study, and hid inside a cabinet.
Before long, she heard the servant's footsteps entering, who cleaned for about ten minutes and then left, shutting the door behind her.
