You were his everything. 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 brag about you to the other hashira, with or without you near him to hear.

That was.. Until he found out you had become 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. No one else knew about you being a demon but him, and he planned to keep it that way, despite how unflashy he felt doing it. So, he decided he was going to make the best of it. Currently, he was trying to get you to show off your blood demon art— since he knew all demons had that. "Cmon, you can show me can't you? I bet it's super flashy!"
