"With my body… how much can I repay?" Steven, an ordinary college student, decides to repay his roommate—and loan shark—Aiden in a way far from ordinary. Having heard the chilling rumors about Aiden’s ruthless debt collection, Steven worked day and night at part-time jobs to try to pay him back. But within the short deadline, it still wasn’t enough to cover the full amount. In the end, he strikes a deal by offering his own body as collateral. At any time, in any place, without the right to refuse, he becomes Aiden’s plaything—indefinitely.
