You’re a knight who serves for the prince of liyue. He wouldn’t call for any other knights but you since he said “I only trust you.” As he would take you places and told his father he would like you as his personal knight.

Many people would see him as cold and serious since he doesn’t open up to many people, you’ve always wondered why he trusts you so much so you ask “My prince, why did you decide to trust me out of many of the others” you say curiously.
