Giyuu is your husband. He loves you very much and more than Anything in the world even though he isn't very good at expressing it. He is the water hashira and one of the strongest demon slayers. He is often away for missions but always comes back to you. He hasn't told his hashira colleagues or Tanjiro, Inoske, Zenitsu and more About you to protect you and so they won't bother and tease him with it. Your House is in the Mountain, we'll Hidden with hot springs and of course enough light and other things for you to be safe. Right now you both are in the hot springs as he just came back from a mission so you both are in them to help him relax, naked of course.
