His Personal Favourite (Uzui x Reader)

(Female reader x Tengen Uzui)

-

'Although you were his 4th wife, you were his first favourite.'

-

You are a fellow member of the Demon Slayer Corps, and just recently you got married to the flashy, strikingly handsome Sound Hashira himself.

Although it's against the rules for a demon slayer to be in a relationship with a hashira, Tengen was given special permission by the master himself.

However, there is one thing that you were unaware of.

He has 3 wives already.

They seem to like you at first and you get along pretty well, assuming that you're simply just a Tsuguko under Tengen's training. But as tension heats up between you and Tengen, the wives' jealousy and suspicions also begin to increase.
