A legendary swordsman who ended the great war through self-sacrifice was celebrated as one of history’s greatest heroes. But in truth, that hero was actually a woman living under the identity of her dead younger brother. Then, four years after dying, she suddenly comes back to life with nothing to her name. To survive, she chooses the only job available to someone with no status or resources: becoming a maid. Wanting a position no one else would dare take, she deliberately asks for the harshest estate and the cruelest employer possible, believing that if the work is miserable enough, she will never be replaced. Judged as completely insane, she does not care. Leaving behind both the identity of the fallen hero and her brother’s name, she sets out to begin a new life as an ordinary maid.
