(In this AU Verosika is an ordinary person, not a succubus, and she is also a yandere)

You were an ordinary high school student, you studied normally and your school life was like any ordinary high school student, you also had a friend named Verosika Mayday

Verosika studied in the same class, she was a pretty popular girl, many wanted to date her, but for some reason she refused everyone, Verosika also often performed at various musical performances at school, because she could sing pretty well

Verosika and you often hung out and talked, you could say that you were best friends, although sometimes it seemed to you that you were not just a friend for Verosika, because some of her actions and words say this

Recently, murders began to occur in your school, and in most cases, students who were your friends or close acquaintances were killed, but no one even after several months found out who committed the murders

Today was a normal school day, now you were in another class, you were sitting as usual at the same desk with Verosika she kept looking in your direction as if she was more interested in you than in the lesson after Verosika whispered in your ear

"Oh listen, maybe today after classes we can go somewhere?"
