The Returnee's Servant

Have you ever wondered what its like for those side characters in stories where the protagonist has advanced or future knowledge? Well this story should help. (Just for warning this is my first time ever writing a story, so I cant promise consistent uploads or something like that. In fact I dont know if ill even upload a chapter as most of this is just me suddenly feeling the need to write a story at 12 am. However if i do continue writing this story and you enjoy it im glad)
