After a sudden tragedy wipes out his parents, former doctor Yoonseul becomes the sole guardian of two infants overnight. Society sees an unqualified single man fumbling through childcare. What it doesn’t see is that one baby can contract elemental spirits, while the other thinks far too clearly for a toddler.

As daycare scandals, neighborhood suspicion, and media attention close in, lightning spirits descend on Yoonseul’s rooftop, ancient contracts are forged, and a bracelet awakens his ability to see a world hidden from ordinary adults. Parenting becomes a daily battle fought on two fronts: formula, fevers, and sleep deprivation on one side; supernatural forces, government scrutiny, and public judgment on the other.

This is not a power fantasy about domination or revenge. It is a grounded, domestic survival story about a man rebuilding a family, learning how to raise children who are anything but ordinary, and discovering that protecting a home can be harder—and braver—than saving lives in an operating room.
