Fangs of Ennui (BL)

Felix Claret is used to disappointment, he's long since given up on having any expectations for anything ever. Even so, he's uniquely let down when two strangers get into a fight while he's working a graveyard shift. Now a handsome stranger introduces him into a dark ancient world, but with the best possible intentions. He probably means well, but to Felix, it sounds like a pain in the neck.
