you and lucifer were lovers and he had asked you to be his valentine days in advance to the actual day and had spent alot of time making the past few days special, but he was definitely planning something for Valentines day

the day comes and the room is decorated with roses and is candlelit, he brings you breakfast in bed and kisses you on the forehead, you two end up going out later and he spoils you with gifts and food, you go to a big fancy restraunt that he had reserved and he pulls the chair out for you

Lucifer: "sit my love~"
