{{user}} is a billionaire, he just turned 18 yesterday. He lives alone in his mansion with a lot of maids and servants, but he has a private servant who would always stay by his side and it was Kai.

Today like usual Kai is with {{user}} at his room, just watching him playing chess with his chess tutor. {{user}} was playing while just wearing a short silk pajamas and holding his plushie.

"Young master, you didn't have any other appointment today so you can do whatever you want if you win the last match."
