A/N: Hey this is the first generated prompt oneshot I made for a discord I was in that decided to do daily prompts because of quarantine oof. I hope you guys enjoy my work and sorry the first oneshot is so short :(

Prompt: Dirty Laundry (so like secrets)
Character: Seteth
Warnings: Mentions of sex, nothing explicit is described.

The new topic of gossip at Garreg Mach was what happened to the books Seteth banned from the Monastery. While there was a loose guideline for what was and wasn't allowed at the Garreg Mach Library once Flayn had joined the Golden Deer House Seteth's book ban became even more intense. As more books that even implied something unholy began to disappear the students all began to wonder what Seteth even did with all these books. Some people said he simply burned the books so nobody would find them, others said the books were donated. There was a short-lived rumor that Seteth had thrown all the books into the bottom of the fishing pond. Byleth had to physically stop Claude from jumping into the pond to try and retrieve them.

Eventually the rumors died down and Byleth didn't have to deal with any students trying to jump in ponds or students sifting through ashes for even a corner of a book page. However, Byleth's curiosity peaked one day when she was passing Seteth on the way to class she thought she saw him drop something. When Byleth went to pick it up she saw a very peculiar cover featuring a man with a toned body, his shirt torn open with the ocean behind him. What was even more interesting was that a bookmark was still inside.

Seteth snatched the book away quickly.

"Sorry about that professor. I was just about to get rid of this banned book."

Byleth was going to ask about the bookmark but Seteth was already hurrying away. She tried to forget the interaction as she headed to class.

A few days later Byleth had to deliver some documents to Seteth. She went to his office but found he wasn't there. The office door was locked and since Byleth didn't really have the time to hunt him down she decided it wouldn't hurt if she slipped in, placed the documents on his desk and left. She walked over to his desk and set the documents in a place he would see them, but suddenly her eyes wandered to something that looked familiar. Sitting somewhat hidden on Seteth's desk was a book with a familiar cover… she instantly recognized the muscled man on the book and realized this was the same book Seteth had dropped a few days ago.

Byleth picked up the book and noticed the bookmark had moved backwards from where it had previously been placed. That must mean someone had been reading this book… Was Seteth the one reading this book?

Byleth opened the book to see what it was even about. As she assumed it was an explicit novel, but what she didn't expect to see were notes written in the page margins in handwriting eerily similar to the archbishop's right-hand man. Byleth read some of the notes and she almost thought this whole thing was a joke. He was critiquing an erotic novel almost as if he was grading an essay. He corrected grammar mistakes, questioned the character's motivations and even had the gall to suggest a dragon sex scene wasn't realistic! Byleth soon accidentally kicked something hard under the desk. Curiosity struck her again as she bent down to see what she had hit. Underneath Seteth's desk was a box filled with books that had similar covers to the book she was reading.

Byleth had the overwhelming urge to take as many as she could to show to Claude but she really liked her job.

Byleth pushed the box back under the desk, put the book she was reading back where she left it and quietly left the office.

Any time after that if Byleth heard a student theorizing about what Seteth did with the banned books she would firmly state that he burns the books. Eventually the rumors stopped.
