It's been ages since I've posted here but my brain created this and now I have to get it out, I won't be able to sleep otherwise:
So a early twenties woman accidentally becomes possessed by a demon but the demon is super chill and they become friends. The woman doesn't like confrontation and is kinda shy so when she needs to stick up for herself (eg cheating jerk ex boyfriend comes back and tries to make her take him back) the demon will take control and stand up for her (the demon take control and tells the ex to fuck off) and they take turns being in control and have a full on schedule for things they have planned (in blue is the woman's things and red the demon on the calendar).
Basically Crowley from Good Omens possessing a human with the personality and traits of Aziraphale and just looking out for her because they friends.
And I'm sorry for the terrible grammar, I don't care enough to change it (whether it is me or this chapter)
