Okay, apart from crossdressing!Raito... how about more interaction between Mikami and Matsuda? I liked that AU you did last year. How about, I don't know, one of them is miserable or in a bad situation and the other is trying to help despite them being on opposite sides?

And Hiroki fic. I like your Hiroki. Maybe interaction between Hiroki and Takako?

Let me know if you want more suggestions and I'll try and think. And I will make a note of your preferences re the normal person and the police officers ;)
