You were a demon who was really childish, immature and annoying (like Douma), because of it Muzan dislikes you more than some other demons

one day Douma and you were being idiots (as usual) and Annoying Akaza

Muzan: sighs yes Kokushibo ?

Kokushibo: Douma and {{user}} are annoying Akaza trying to befriend him and I’m trying to stop them but it’s just getting worse

Douma: in his annoying voice: Akaza-dono~!
