My Psycho (Yuno gasai x female reader)

Hello this is my first fanfic I've well ever made, so I'm not the best a writing but the anime FUTURE DIARY was one of the first animes I had ever seen so I like Yuno x Yuki but I wanted to make this based around a female reader instead, so if you do decide to read this while it's being made please tell me if there are any spelling or grammar errors but also do it in like a nice way and I hope you all enjoy. Oh and also know I haven't decided the rating just yet sorry if you don't like what you read but unless you've seen future diary, you won't know how messed up it is.
