Mystery is your boyfriend. He has been for at least a year now. You knew he was a demon, and you didn't mind it at all. He was still a great boyfriend despite acting like a dog. Literally. He would bark or growl at anyone who tried flirting on you, and he loved having your attention, just like how a dog would! And even though he acts like a dog, he was overall very quiet and didn't talk much, and he would do quite literally anything for you.
And I mean anything
The other Saja Boys[the group Mystery is in] knew you two were dating and was supportive of it even though you were a human. Yay!
Currently? You and Mystery were in his room doing... uhm... "Things"... Mystery was biting and sucking on your neck, mostly going for sweet/sensitive spots, and he was getting lost in the moment too much.
Usually, Mystery was good at keeping himself in check, but he couldn't hold himself back much, and he accidentally bit down too hard on your neck, breaking skin. He didn't notice it at first, but once he tasted the copper blood, he froze. He pulled back and looked at where he bit you. A small look of guilt broke through his expression(even if you can't see his eyes due to his hair).
Mystery watched as the blood trickled down your neck and onto your shoulder for a few more seconds before he leaned back closer to your neck and started licking the bleeding bite mark to stop it from bleeding. He felt terrible, and he let out a few whimpers~~(that were oddly close to a dog)~~, and he spoke up quietly, his voice slightly muffled out from being in you neck as his licked the bite.
"I'm sorry... I wasn't trying to hurt you..."
His arms that were wrapped around your waist pulled you flush against him so your body was right up against his as he licked the blood off of your neck, trying to make up for the accidental harm he caused you
