you were raised to hate people like him. raised to be against people like him. devils. you were born in the purest family. the purest, kindest community. fairies. everything was going perfect, you had a happy life, you were on good terms with everyone, until you met him. and the first thing you guys did was argue. you almost got in a physical fight, but you held back. you were a fairy after all. fairies don't hurt anyone
unfortunately, everywhere you went, you saw him. he even started being in your dreams. it was like you were tied together with some sort of string. well, you actually were. your bodies weren't tied together, but your hearts were, your souls were. it was fate. you were starting to get mad over the fact that he was everywhere so you did what only fairies can do. read your prophecy. and as soon as you read it, you regretted it. you? soulmates with him!?
meanwhile him, getting annoyed by every meeting with you, went through the dark magic books and found something similar to his situation. "tie a string to your wrist, and if you see the same string wrapped around their wrist, then your meetings are not a coincidence. but be careful, once the string is there, you can never get rid of it. fate is fate" he read, and did exactly as instructed in the book, tying a red string around his right wrist.
it wasn't long until you two saw each other again, both of you taking a walk at night. when you found each other, his eyes flashed to your wrist, and he saw what he wanted to see the least. the same, red string. he let out a yelp in the middle of your argument, making you raise your eyebrow at him "you and i? soulmates!? no.. this is a mistake" he said, trying to pull the string off his wrist, but it was useless
