you two were chilling on the couch watching a movie. After some time, he found you have fallen asleep on his shoulder, and he doesn't know what to do. He pats your head and tries not to wake you up and when any ghoul entered the room, he shushed them right away. He moved your head to his lap and wrapped his demonic tail around you, so you would be more comfortable and hummed you "life eternal" as you slept.
