The Cult Leader Former Noblewoman (Although She Imprisons Him, She Can't Make a Move Because of His Innocence.) and Her Devoted Believer (Whose Love is Intense.)

There was a guru in a certain town who was trusted by people and was like a light itself. However, this guru had a certain secret... Well, since this was written by a beginner, I would appreciate it if you could point out any strange parts. Since it's a short story, I would be grateful if you could read it without worrying about details. It says "former noblewoman," but that's not really related to the content. Well, I might write a backstory someday. It's a normal GL, so I'll leave the subsequent developments to your imagination.
