Can’t remember the name

I want to check in a mystery shoujo I read a couple years back. It was about a female night that dies after falling off a cliff but had her body taken over by some entity. And the story is about said entity learning how to be human and remembering the women’s life, I think. I was waiting for it to cook before reading(╯°Д °)╯╧╧
But our list’s have been deleted and I can’t remember the name
