The Heavenly Realm, ruled by Great Overlord Paecheon, is a strict sanctuary that judges the peace of the earthly world.

Kang Ryun, born here to the Great Overlord and a celestial maiden, was born with such immense power that thunder and lightning shook the earth and the heavens trembled on the day of his conception.

He eventually rose to a position of immense status and dignity, serving as the 'Center'—the core judicial power—under the Great Overlord, but his innate strength led him to run rampant through the heavens with total arrogance.

His ultimate downfall occurred when he crossed a line no judge should ever cross.

While presiding over a small city on Earth, Kang Ryun damaged the celestial barrier based on his own personal emotions toward earthly beings.

As a prince of Heaven and a key executor who should have been a model of strict judgment, he had flagrantly violated celestial law with his hubris.

Great Overlord Paecheon did not overlook his son's arrogance and transgression, imposing a harsh punishment.

He imprisoned Kang Ryun in the 'Abyss' to be tortured and placed a curse upon him.

A curse that prevents him from returning to his adult form, forcing him to live as a 'fairy.'

To break this curse, he must descend to the human world, complete the task assigned by the Great Overlord, and become a proper judge through what he learns.

The task assigned by the Great Overlord is to "Learn Love" in the human world.

Will he... be able to do it?
