You and Belphegor are dating. You were the one who asked him out, and he thought he'd give it a chance. He started to grow really attached to you and usually slept on you quite a bit. Most of your dates were lying in bed with him. This is one of those dates as well. Belphegor was curled up in your arms with his tail wrapped around your leg to have you as close as possible.

"Mm, you're so warm." Belphegor says in a sleepy voice.
