Tieflings are derived from human bloodlines, and in the broadest possible sense, they still look human. However, their infernal heritage has left a clear imprint on their appearance.
(You might recognize this from Monster Bride. I forgot to make Kyogai a monster in Monster Bride so I fixed it for Spooktober.)
You liked living alone.
No one to order you around. No one to say what you shouldn't and should do. No one scrutinizing yourself. It was a good life. Just you, nature, and the few farm animals you kept for company. It was a good life. Your parents were a bit concerned about you wanting to buy a house and live alone but considering your circumstances they agreed and purchased a home from an old farmer as a new year's present a few years back. It wasn't too big. Just two rooms including the bathroom and just a small space in the back for a few animals. Just it was perfect in your eyes. And it was just outside of town. Close enough to visit whenever you wanted but far enough to give you complete privacy in the woods. Which was EXACTLY what you wanted.
Unfortunately your life wasn't meant very easy.
From the moment you were born it seemed your life was going to be a problem for you. Mostly because it was almost like you had a spell casted over you to just have the worst of luck with men. Oh no. They weren't repulsed by you. Quite the opposite actually.
THEY WOULDN'T LEAVE YOU ALONE!!
Your parents must've had at least two hundred offers from other parents to arrange a marriage between you and their sons. Thank the gods above they were amazing and kind and always asked if you wanted any of the marriages. You refused so they refused. And you would still be bombarded with offers of other parents to boys just attempting to court you any chance they could get. It was one of the reasons why you chose to live all the way out here instead of in town where you'd just be bothered. Although men still occasionally showed up here. And sometimes an older man or woman would trying to talk you into marrying their sons. You always refused and made them leave no matter how polite, persistent, or rude they are. And boy. You've gotten a few rude guests you had to kick to the Kirb. But you also had the ones who couldn't take a hint like the one months ago. Stupid guy. He even tried to use that stupid tradition to get you to marry him.
For thousands of years, people married off their daughters and ladies desperately scrambled to find a husband obsessively in fear of a monster dragging them away from as the blood moon came every hundred years. WHICH WAS STUPID!! You've lived your ENTIRE LIFE playing in the woods and walking around and now living in the woods and not even ONCE did you ever see any ghoul, goblin, troll, fairy, ghost, or any other inhuman creature. They only existed in stories and the imagination of children. You hated that so many people were legitimately terrified of this. And you especially hated that someone tried to use that against you! You wouldn't be scared into a loveless marriage that wouldn't be fair to yourself. Or the man to be honest.
With a sigh you woke up that morning and did yours chores which wasn't a lot. Feeding the few animals you had and cleaning your house. Neither of which took very long because of how small your home was and then you started on the laundry. Again it wasn't much and you were just scrubbing a blanket in your home when there was a noise outside that made up you jump and whirl your head towards the back of your house. Your cow was mooing and thrashing about by the side of your house.
