Cat's Cradle. A clearing in the forest where a million indestructible threads criss-crossing over one another to connect one branch of a tree to another. It's rumored to link the humans together, but of no importance to the dead who roam around concerned with their own affairs. But Myungsoo's not like most of the dead- he can remember- so he spends day after day untying and retying the knots to break unhealthy relationships and (hopefully) create good ones. Myungsoo sure he'll spend eternity in Cat's Cradle, and he doesn't mind one bit.

That is, until a mysterious duo shows up one day with news of a reaper, who will cut apart every thread of the forest. Suddenly, Myungsoo's not so sure of anything anymore.
