All members of the family except his father have inherited particular superpowers and they come from a long line of similarly blessed ancestors.

But as the series opens, the family's superpowers on the wane, they are dysfunctional and failing to meet their expenses despite owning a substantial office building.

The family has also experienced tragedy, including the death of Gwi-ju's wife, which left him to raise his teenage daughter Bok I-na on his own, often poorly.

A side plot is a teenage coming of age story for I-na who conceals, and then reveals to the family, that she can mind read other people if she makes eye contact.

At the beginning of the series the entire family have lost their abilities due to chronic disease and incompatibilities with modern lifestyles — depression, insomnia, drinking, obesity.
