This will be explained in the story if it's to confusing in the story come back here
Little explanation since I just made this up
Soulmate AU
•Every person in Kunimi's family has a Soulmate
•If your soulmate hurts you a heart string will snap
•If too much heart strings snapped you will die since your heart will get disorted
•They need to choose a soulmate
•If they don't find a soulmate they will get sick or die
•Kindaichi is Kunimi's soulmate
•If a string snaps you will get trouble with breathing and it will feel like something got ripped out of your heart
Your opinion on this soulmate AU?
The thing with the heart strings is actually true and you can really die of it
