Kim Chaewon had rules. Six of them, written neatly on a sheet of paper and handed to Kazuha the night they signed the contract. No real feelings. No unnecessary touching. No questions about the past. No crossing the line between fake and real. It was simple: pretend to be Chaewon's girlfriend long enough to make her ex regret leaving her, and in return, Kazuha gets paid. Professional. Temporary. Controlled. At least, that was the plan. But somewhere between staged dates, late-night phone calls, and moments that didn't feel rehearsed anymore, the rules started disappearing one by one. And the worst part? Neither of them noticed when pretending stopped.

"Take my name, take my power, and crush everyone who ever looked down on you." On a cold, rain‑soaked night over the dark river, Kim Chaewon stood ready to let everything end. She's been broken by betrayal, abandoned by her family, and stripped of every reason to stay alive. But just as she leaned toward the fall, Nakamura Kazuha stepped out of the storm: brilliant, wealthy CEO of The L'Aube Hotel, admired by the whole world... yet secretly living on borrowed time, her own heart failing beat by beat. What began as a desperate bargain: thirty days of shelter, work, and safety, slowly changes into something neither expected. Two women, both living quietly on the edge of giving up, find in each other the strongest reason yet to keep breathing. It was meant only to be a temporary rescue. But soon, it becomes far more: a shared secret, a quiet war against every unfair thing that hurt them... and a lifeline strong enough to hold even against death itself. To Chaewon, it's a second chance. To Kazuha, it's the last beat of a heart that finally found something worth protecting.

"Do not try to be my friend. I hired you to be my secretary, to make my work easier and keep this floor running smoothly. I did not hire you to be my partner, and certainly not my confidante. I do not want to chat about the weather while we wait for a meeting to start. I do not want to be asked about my weekend or if I've eaten lunch. We are here to build cities, to plan transit systems, to make Seoul a better place to live, not to make memories or share stories. Keep our interactions strictly professional." To the world, Nakamura Kazuha is the 'Ice Queen of NIUD' a cold, calculating CEO who builds skyscrapers and shatters careers without blinking. She doesn't have a heart; she has a blueprint. Her life is a series of perfectly timed meetings, sharp suits, and an iron-clad reputation that no one dares to challenge. Enter Kim Chaewon. A girl from Daegu with a bright smile. She was supposed to be just another replaceable secretary in a long line of failures. But behind the heavy mahogany doors of the 45th floor, the cold glass of the Nakamura empire begins to crack.
