Mitch — the man who lost every last hair on his head after reaching the peak of his power — wakes up one day to find himself inside a novel he had read before, reincarnated as a minor extra character whose name is never mentioned anywhere in the story. The "System" appears before him and assigns him various missions in exchange for granting him power, but Mitch flatly refuses the offer. To him it is annoying and pointless, and he is already too strong to need any more. Faced with this unexpected refusal, the System decides to change its reward and make the one offer that matters to him: [One hair grown on his head for every mission he completes successfully!] Mitch accepts the deal enthusiastically and begins carrying out the missions... without knowing that everything that passes between him and the System, including the thoughts he believes are secret, is being watched live by the heroines of the novel.
