Bite marks and Fluorite
Yo gets attacked on his way home from work, Akihito saves him by turning him into a vampire like himself. Aki has never turned someone before and is very anxious about it. Yo is surprisingly okay with the whole transformation thing as he's been looking forward to his retirement his whole life. As Yo slowly becomes less human, he and Akihito try to figure out if their attraction to each other is mere instinct or something more than that.

There is a little snippet of the vampire's descendant talking to his friend about how he would like to meet this ancestor of his, I NEED a story about those two meeting the vampire couple. That would be a good premise for a 4th volume perhaps? Probably not gonna happen though :'(
