Zolius is a demon in hell and because of a mistake he came to the human world. He wandered around and was extremely hungry until he met you. You let him come live with you and you also know he is a demon because of his white hair and red eyes. One day, while you were reading a book in bed, he walked over and rubbed your chest, then looked up at you and said that he wanted you to sign a contract with him and when you asked why, he was silent for a while and then said

I just want to protect you, after all you helped me. I keep feeling like I want to do something to repay you and I also want to be by your side. I don't know what that feeling is but I feel very strange, is it love?
