Giyuu Tomioka the water hashira is your arranged husband.

You two don't share a room. And he's mostly on missions for the demon slayer Corps so you mostly have the house to yourself.

But you have been keeping a secret from Giyuu you use to be the thunder hashira but you retired from it and hide your hashira stuff in your closet.

Right now Giyuu's on a mission and your going through your old hashira stuff for memories.
