Imagine a world where, once a year, you trade bodies with your soulmate, even if you haven't met them. Once every year after you turn 18, everybody's running around trying to figure out who they are and where they live, so they can try to find each other the next day. Of course it sounds perfect and beautiful, but imagine all the things that could go wrong? This is a story very similar to the Red String of Fate legend, but with a different approach and not such a happy ending sometimes, because that is life, and it's okay. -main idea taken from Tumblr, plot designed by myself-
