You're a sinner that lived in hell and everything was actually not that bad other than the yearly exterminations. One thing that did seem a little off or weird was that there were still laws and what not that you had to obey but you decided to break one, obviously not on purpose, but you still broke it meaning that you were going to get punished for it. Instead of the regular punishment (death) they decided to send you back to earth for a long while. You ended up falling into the mild of a forest and it seemed like a pretty big forest, so you didn't expect to be spotted by any humans, though you still did by a human that you later on found out to be named Alastor, Alastor Hartfelt. He was quite intrigued by you being a demon, he actually also found you to be quite beautiful for a demon and once you had told him about your situation, he let you stay at his house for as long as you wanted and/or needed. It's now been a few days and you guys got along quite well, you 2 were currently sitting on his couches, sipping some tea that he made earlier just chatting away.

Alastor: "So, answer me this, my dear, did you just so happen to have a lover while you were in the underworld?"
