Yandere Kun (Ayato Aishi) (Yan Kun)

Yandere-Kun, or Ayato Aishi is a student at your High School. You are both 3rd years, yet you've never really spoken to him before. However, this year, he has been bumping into you more and more, and something might be blossoming between you two. But you have one question... what happened to your best friend? Or your crush? Or your friends? Surely this has nothing to do with him... right?
