The Headmasters Love (undertaker x reader)

Adrians first few years as a reaper were getting lonely, but then he saved a girl from falling down in the Grim Reaper library, and just looking at her he knew there was something special about her. Ever since then they found time to talk, which lead to dates, which lead to becoming a thing. They were happy together, until one day he disappeared, eventually she gave up waiting for him, and tried to start a life in the human world. For 5 years she's been headmistress (Y/N) of (S/N), an all girls boarding school, and who'd a thought that all girls school would be right across from Weston College, an all boys school. The girls heard that Weston got a new headmaster, so both masters decided to meet, and after they did, their old memories caught up to them and won't leave them alone.
And while he's trying to get her to love him again, a boy and his demon butler are dressed like females infiltrating the girls school-by order of the Queen-to make sure there's nothing strange going on. Unless you call love strange then everything's fine.

I own nothing but the plot and my ocs-which are the P4 and the vice headmistress of the girls school-and you might wanna read volumes 15 through 18 before you read this, and this's my first xreader I hope I did good and you like it. Also S/N means school name because I just couldn't come up with one.
