Debuff Master drops Han Tae-Sung into a brutal reality where gaming prowess means nothing. Betrayed by allies, hunted by rivals, and drowning in real-world debt, he loses everything overnight and plummets into darkness. Stacked against him: raw talent, inherited wealth, powerful connections, and sheer luck—advantages the ordinary player can never overcome. But fate offers redemption. Armed with a mysterious hidden class and a second chance, Tae-Sung rebuilds from rock bottom. What begins as a desperate scramble for survival transforms into something darker: a calculated campaign for vengeance against those who destroyed him. In a world rigged against the powerless, he discovers his greatest weapon isn't strength—it's the will to fight back.
