Even though Ji Jiri is the most powerful person in the world, he lives to be the weakest.

His mother, carrying the strongest power, and his father, from a gangster family, that’s where Jiri was born. Ever since he was a newborn he showed his Herculean strength demolishing his own house, furniture, and even his dad(?).
In order to let him live a normal life, his parents brainwashed him.

“You are the worst to ever walk on earth.”

“Never get close to anyone.”

This is the story of Ji Jiri’s personal growth and overcoming of traumas, the strongest man on earth.

(Note: This "worst to ever walk on earth" seems to be error and should actually be you're the weakest.)
