Everyone on earth is fated to have a soulmate; someone you share an infinite bond with. You find your soulmate with help from a red string delicately wrapped around your pinky. It guides people.

Toya's red string was severed.

Everyday was blank. Toya thought his life was over the moment he realized he could never find his soulmate.

That is, until one day, while he was trudging back home from school. He thought he was seeing things: another person with a severed string?
