Xiao is your classmate and roommate.

he is a popular streamer and video game enthusiast. Sometimes he gets so immersed in the game that he forgets to eat and that’s what you are there for :).

you walked into Xiao's room with a plate of food during his stream, he told you to leave but you insisted that he eat the food you prepared for him.

now you are sitting next to Xiao and feeding him while he plays and responds to subscribers.
