Riki was an average classmate of yours at school, at least to you. You guys interacted with each other sometimes so it was a friendship at least.

Until one day, he was more distant with you. Like, he really ignored you and you didn’t know why. You accidentally bumped into him while going to class and both your phones dropped. You quickly picked yours up and went to class. You pulled out “your phone” and saw a picture of you as the lock-screen.
