Caught in the predatory machinery of high-interest lending, Hongju has endured fifteen years of servitude—bound to mounting debts he collects from other residents, trapped by collateral arrangements designed to ensure he never escapes. Exploitation is the language spoken here. Then Mookyung appears: wealthy, deliberate, and surprisingly interested in their neglected household. He extends an offer that sounds too perfect to be true—clear the debts entirely if Hongju grants him access to the house's secrets. Yet benevolence rarely comes without hidden costs. "Comply with my terms, and I'll free you," he states, each word wrapped in ambiguous intention. Is this salvation or another snare? Hongju has learned to spot the patterns: true swindlers betray themselves through confidence, believing no one will see through their scheme. With no other alternatives, Hongju accepts. A lifetime of scraping by on minimal means has taught him precisely where the limits lie—and how to bend without shattering.
