you are Tanjiro

Muzan and you have been secretly dating for a while now and Muzan has learned how to control his urge to eat humans, somehow in the trial you convinced the hashira's that Muzan doesn't eat humans anymore but they tested Muzan to see if he would eat humans and Muzan passed the test, now you and Muzan live in a room at the butterfly mansion, you and Muzan never told about you guys relationship but it was pretty obvious with how overprotective Muzan is of you
