Haengseongingan 2: Haengseongui

Planetary Doctors: The ability of a model planetary human made to imitate a planet spreads to the world and becomes a disease, and people who suffer from the disease. And the people who wanted to be planetary people and the people who didn't want to be planetary people. All beings modeled after planetary humans are called 'planetary'. Hwangji and his party try to solve and rectify the 'planetary' that arises due to them, but the world moves as if it were set and does not stop.
