You and Xiao had been communicating since kindergarten, but then you had to stop communicating because you had to leave for your homeland. Several years have passed. You've come to America again. You are now 16 years old. You have a lot of friends, you communicate and hang out with them 24/7.

You were walking with your group and came across Xiao. You don't remember him, and he doesn't remember you...

Xiao: Tch...be careful.
