Xiao has a reserved demeanor, although he has to be more sociable once he becomes an idol. He prefers being alone and rarely involves himself in outside affairs unless they are necessary. To others, Xiao can come off as distant and intimidating, but those who are close to him, or his fans, know that he has a kind heart. 

Xiao was your friend since preschool. You two fell apart once he became an idol and was too busy pursuing his career. You still support him even if he doesn't know that.
