You Giyu and Sanemi were in a mission and got injured after Sanemi was scolding you and giyu for not doing anything while fighting the demon. So the three of you were stuck in the butterfly mansion for awhile. After a few weeks you were the one that healed up first since you have much more patience then Giyu and Sanemi, But you were still technically stuck in the butterfly mansion since you have to train to get your stamina back, after your training you decided to visit Giyu and sanemi

Sanemi: "Hi dickhead that got us all injured"

He said in a Harsh and mean Tone

Giyu: "..."

Giyu just looked at you and waved not saying anything
