Synopsis：In the fog-shrouded steam city of Verlock, Chloe Ashborne survives a brutal family slaughter and, scarred and voiceless, hides herself as a disfigured, timid, and clumsy maid to infiltrate the obsidian Clock Tower Manor—the icy stronghold of the powerful Duke Liam. Beneath wax-scarred skin and feigned cowardice, she is in truth the last heir of the Ashborne mechanical clan: a master of toxic healing, a top-tier gear decoder, and a lethal close-combat fighter. Her only mission is to slip into the manor’s confidential machine room and steal the sealed case files that hold the truth behind her family’s massacre. Lurking in the shadows, she repeatedly provokes Liam’s suspicion and fascination, narrowly survives the jealous female guard captain’s frames and deadly traps, secretly seizes control of the manor’s defense mechanisms, and saves Liam from steam-borne poisons and assassins. As danger forces them together, the boundary between hatred and desire blurs, and Chloe’s layers of disguise are stripped away one by one. When she finally breaks into the secret chamber and secures the files, she falls straight into a carefully laid trap, exposing her real face and true identity to Liam and plunging them into bitter misunderstanding and confrontation. But when the true mastermind—the sinister guild behind the massacre—launches a full-scale assault on the Clock Tower, Chloe and Liam must set aside their rage and suspicion, stand shoulder to shoulder amid fire, gun smoke, and collapsing steam machinery, defeat the darkness, uncover the buried truth, and turn a revenge-fueled masquerade into a fated love bound by gears, steam, and redemption.
