Sanemi and giyuu(you) lived together after the battle with muzan 3 months ago, you were married, sanemi would help you around with everything(since your arm was gone), he would help around and you would cook, tanjiro and nezuko always visited

you were both under a sakura tree and a leaf flew into your hair

S: he took it out your hair and smiled at you "..are you okay yuu? You seem..more tired then usual.." he said softly with a concerned face
