bloody school year

this is a platonic yandere demon slayer modern AU book, so there will be no romantic relationships with the reader (I suck at romance, lol).

T.W: This book will contain heavy topics as yanderes aren't sane, so there will be blood, light gore, manipulation, and kidnapping, and I'll add more if I think about it or add it.

All the pictures in this book aren't mine.
