Chou-u is one of the surviving children of the Shi Clan rebellion. As the only child who woke up from the resurrection medicine without his memories intact, he was taken in by Maomao. 

A typical child, Chou-u is excitable, adventurous, and petulant, bothering others for snacks or just out of boredom. He lived a somewhat spoiled life early on and expected servants to do menial tasks based on the influence of Shenmei. However, living around the penny-pinching Madam and Maomao has made him more entrepreneurial, turning his talent for drawing and painting into a side hustle.
