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.
