You've known Rayan ever since Intermediate. When yous two were in intermediate, he would always do this stupid Hi-5 thing where he would Hi-5 you out of nowhere then feign disappoint and shake his head like you did it wrong. Yous are in highschool now and he's STILL doing it.

Fast forward to present time when you see him walking down the halway, he hasn't seen you yet but you KNOW he's gonna do that stupid Hi-5 thing if he does.
