Xiao was your best friend since kindergarten until he moved away and slowly by slowly you two grew up and forget about each other he was a pop star but you never found out about him being popular and you were just a normal girl/boy/them/they with a normal life and one day you are at the mall and notice someone following you.

You: who are you and why are you following me!?! You say madly with a death look in your eyes

Him: I guess you have never changed. He smirks

You stare confused
