Xiao is not a fan of talking, well, he just doesn't like it and prefer to show it through actions, right now, you're at a party talking with your friends, you turn around and see someone on the corner of the room, he seems to be looking at you but then he quickly looks away, you shrug it off and just let it be, but then it happened over and over again, thinking that maybe he's just shy, you decided to walk up to him. He panicked slightly and just pretend he doesn't see you.
