The game ended. Yeon Seonwoo opened his eyes to an unfamiliar ceiling, only to realize he had been pulled into the very world he thought he had conquered. Now he exists as a minor character no one would notice, a ghost in a story already written. His only goal is to find a way back to reality. But that plan shatters when he is kidnapped by Lee Jehee, the S-Class hunter and protagonist of this world, a man whose power is matched only by his crippling insomnia. Jehee has heard of Seonwoo’s mentalist abilities and wants relief. Yet for a man teetering on the edge of sanity, the word help takes on a dangerous meaning. Seonwoo finds himself forced into a dubious contract, not as a partner, but as an exclusive supporter. A servant. Bound by the agreement and summoned at will, he is dragged into a web of power plays, hidden agendas, and unpredictable dangers that threaten to swallow him whole. His wit is sharp, and his skills are real, but can he outmaneuver a master who sees him as nothing more than a tool? Or will the chains of this contract bind him to the game world forever?
