Woomin, a talented hacker, infiltrates Taeyoung Corporation at the request of a criminal organization. However, he was caught by the security network in the middle of it. Instead of reporting Woomin, the CEO of Taeyoung Corporation, Beomhyun, proposed a contract that is nothing short of a slave contract. "Why don't you pay me back with your body? Mr. Criminal." Woomin, who had no choice but to sign the contract, had to do all sorts of weird and dangerous errands ordered by Beomhyun.
