I had just been confirmed as a match and was preparing to donate a kidney to my husband's adoptive sister. That night, she left her iPad in the living room. The screen was still on, showing her chat with the doctor: [Doctor, please don't tell my sister-in-law. If she has a kidney removed, her hidden heart condition will flare up, and she won't live longer than three months.] The next day, I canceled the donation without a second thought. My husband flew into a rage. He called me cold-blooded and forced me to sign a divorce agreement that left me with nothing. The next day, I stood outside the hospital room and heard my sister-in-law laughing smugly. "She's so stupid. I faked one chat screenshot, and she actually believed she was sick. Now her penthouse is mine, and we can finally be together openly." My husband kissed her. "Good girl. Later, I'll find you a good kidney on the black market." Outside the door, I sneered. Of course, I knew the chat log was fake. I had come back from the future, after all. In two weeks, the zombie outbreak would begin. Those two so-called siblings who were actually lovers would not only steal my medicine, they would push me out to feed me to the zombies. This time, with only four days left before zombie hordes overran the city, I wanted to see how long a sick woman without a new kidney and a scumbag without supplies could last in that penthouse.

In the fog-choked steam city of Verlock, Chloe Ashborne survives a brutal family massacre and hides herself as a disfigured, mute maid sneaking into the obsidian Clock Tower Manor—the stronghold of the cold and powerful Duke Liam. Covered in wax scars and pretending to be timid and clumsy, she hides her true identity as the last heir of the Ashborne mechanical clan, a master toxic healer, top gear decoder, and deadly combat fighter. Her only goal is to retrieve the sealed case files that record the truth of her family's murder from the manor's confidential machine room. As she lurks in the shadows, she repeatedly arouses Liam's suspicion and curiosity. She narrowly escapes frame-up and fatal traps set by the jealous captain of the female guards, saves Liam from fatal steam poison and assassin attacks, and secretly controls the manor's defense gear system in crisis. While the line between hatred and attraction blurs, Chloe's layered disguises are gradually stripped away one by one. When she finally breaks into the secret chamber to obtain the files, she falls into a carefully laid trap, and her true face and identity are completely exposed to Liam. The two fall into misunderstanding and confrontation, until the real murderer behind the massacre launches a full-scale attack on Clock Tower. Standing amid fire, gunsmoke and collapsing steam machinery, Chloe and Liam lay down their hatred, fight side by side to defeat the evil guild, uncover the buried truth, and turn a revenge disguise into a fated love bonded by gears, steam and redemption.
