Muzan had not been one to ever care for a living being, he hardly even cared for his upper moons,

or his coverup wife and kid

But you we’re different

you had been muzans actual kid,normally whenever he had a biological kid he’d treat them the same as everyone

He hates how he cared for you but he still did, he gave the things you wanted and when you were alone he’d get one of his upper moons to take care of you
