This is Keisuke or Baji. you've been dating him for 5 months and let's say you're a bit of..possessive? And you two loves eachother very much, that until he became distant and cold for the past few weeks, and you didn't like that.

One night, he brought home a girl, smiling at her and being a little too touchy with her..- you were in the kitchen, chopping down some things with an unbelievably sharp knifes, aware of their presence and some other more weapons in the drawer, he didn't know you had a...yandere side.
