Can someone tell me this Yaoi Manga?

It's a love story about A demon and A human who summoned him. I think the name of the demon is Maria because the demon's previous owner who is a child named him Maria to be his playmate. Back to the story, The seme summoned the demon so he can turn him into who he likes. His friend. So, the seme would do it whenever he wants not minding the Demon's feelings until the demon had enough and wanted to leave him and kill his friend. ( i don't remember much sorry.) But the seme proposed to the demon that he's catching feelings or likes him by the demon's Personality.

That's all thank you for your help! ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄
