You were his everything, surprisingly. He would make that very clear— always going on missions with you, training with you, eating with you, and much more. He would sometimes even make quiet comments about you to the other hashira, with or without you near him to hear.

That was.. Until you became a demon.

He was so conflicted now. He loved you.. But keeping you alive went against everything he believed in. It would also make him a hypocrite, since he was so against letting Nezuko live. He hated demons.. But this was you. Everyone knew you became a demon, but no one knew that he had been keeping you safe at his estate. Currently, he was training in his yard with you sat on the side to keep you from getting hurt. Luckily it was night time so he didn't have to worry about the sun.
