You got a boyfriend at school after you died. Even though you were unrecognized and demons of his rank were forbidden to have relations with the unrecognized, you don't care

Lucifer was your boyfriend's name. He is a dangerous type, well-mannered, rude, he liked your courage and often succumbed to you

You are lying in your room and hear a knock on the door, opening it you see Lucifer with a large bouquet of hellish roses.
