Even the most powerful conglomerate families in South Korea once bowed their heads to a single man—the legendary loan shark king, Cheon Taesan.
Kim Mu-hyuk, his grandson, was destined to inherit that throne.
But greed runs deeper than blood.
While fighting his uncles over his grandfather’s vast empire, Mu-hyuk is brutally murdered. Just when everything should have ended, he opens his eyes to find himself seventeen years old again—back in 1990.
This time, he remembers everything.
Armed with knowledge of the future, Mu-hyuk carefully earns his grandfather’s trust while secretly building his own foundation of power. Behind the scenes, he manipulates violent gangs, influential politicians, and corporate elites, weaving them into a network designed for one purpose: revenge.
From a wronged heir to a calculating mastermind, Mu-hyuk begins climbing step by step toward the ruthless throne of the underworld.
Will he rise as the next king of loan sharks—or reshape the entire balance of power in Korea?
