Do Kyungsoo comes from a long line of Soul Weavers, a group of people who have the ability to divide their souls into fragments and transfer—Weave—these fragments into another being, thereby making it their Familiar.

Kim Jongin is your average human. And, in Kyungsoo’s opinion, not exactly the kind of Familiar that suits a pureblood Weaver like him. But, apparently, Kyungsoo’s opinion doesn’t matter because it was Jongin who came out of his portal during the summoning ceremony.

And thus begins a lifetime bond between this unlikely pair.
