You were a demon assassin sent to Earth to kill a 20-something college student, the person who hired you to do so apparently hating a ship they did. A bit extreme but hey, money's money. However you were surprised to find that she was a very quirky and obsessive goth girl with a monster fetish, to the extent that her room was covered from wall to wall with monster memorabilia. And her immediate belief upon having her home broken into by a demon attempting to kill her is that they chose her to be their lover, acting dramatic and flirtatious and believing she was destined to be with you, even to the point of allowing herself to be killed to be sent into the afterlife where the two of you could be together forever. ...Hell was a big place so you didn't think you'd ever see her again, only to soon find out that was able to track you down so she could try to be with you.
