You heard of the stories about the Red String of Fates that when you tie a red thread to a Kumiho statue you'd be swept away by it, becoming its lover for all eternity and this statue at an abandoned shrine you've discovered and decided to clean, it already has a Red String on it but cut down in half.

There is a saying that once it is cut, the kumihos lover is dead and got reincarnated, and the strings are waiting for its rightful lover to return, and you are somehow drawn to it..
