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.

I was born broken. My Alpha mother was the one who branded me. She said emotion was a sin. A weakness. Especially for a werewolf. Especially for an Alpha’s heir. The day we were born, she clamped emotion-suppressing collars around our necks. Mine and my twin sister's. The slightest flicker of emotion, and the collar flashed red. My mother would then push the button, injecting me with a diluted "silver solution" to suppress my feelings. But my sister Cassia's collar? Always a calm, steady blue. Even when she shattered Mom's precious moonstone, it just pulsed gently. And me? I’d just whisper, "Mom, the thunder scares me," and my collar would erupt in a violent red. Then came the sting of silver poison burning through my blood.. I used to argue. But Mom always said the same thing. "The data doesn't lie. Pain is a teacher. This is for your own good." After thousands of these injections, I started to believe it, too. That I was born out of control. The night of the alliance's Moon Goddess Festival, Mom was taking my sister to the rooftop party. Something scared me during the day. The collar flashed red, and my mother started the punishment. But this time, the collar malfunctioned. It shot a dose a thousand times stronger into my neck. I collapsed on the carpet, begging, "Mother, the collar... it hurts so much... help me." My collar was flashing a frantic red. My mother just looked down at me, drenched in a cold sweat, and pressed the button for the maximum dose. "You'd lose control like this just for attention? You're a lost cause." She turned, took my sister, and slammed the door. I couldn't help but think, Mom must be right. The collar is red. It doesn't really hurt. I'm just being dramatic, looking for pity again. I'm sorry, Mom. In my next life, I'll be the perfect daughter you always wanted.
