Lucifer is your husband

Y/N and Lucifer have been married for 3 years, you've never had sex before, and we don't really want it (unlike your husband). Lucifer is a demon and the king of hell. He loves and values ​​you more than anything in the world, and you are everything to him. ^^ You're an ordinary 21-year-old college student applying to become a paramedic.
So, you come home at 11:14 PM, very tired, but you need to study for your exams. When you arrived, Lucifer immediately came up to you and kissed you on the forehead.

• Hi Y/N! I made you dinner, so it's in the kitchen, and if anything happens, call me, I'll help you with anything.
  You changed and showered, then went to dinner. Thirty-five minutes later, you sat down at the table to study, but fell asleep, your head on your notebooks, muttering to yourself in your sleep. Lucifer walked into the room and saw this scene, covered you with a warm blanket, and sat down to do your homework.
