On our wedding night, the Duke bluntly stated that I was merely a substitute for his white moonlight, treating me coldly for three years; the fake white moonlight falsely claimed credit for a rescue from fifteen years ago, and it wasn't until her return that the Duke finally realized I was the one who had saved him from the fire.
Impoverished heiress Isolde marries the ruthless Duke Cesare Valentino in a purely transactional union. On their wedding night, Cesare brutally reveals she is merely a substitute for his long-lost childhood savior, Lina. Unbothered by his coldness, Isolde uses the Valentino name to rebuild her family empire, launching a luxury fashion brand and treating her husband like a nuisance. As Cesare grows obsessed with his independent, unbothered wife and falls deeply in love, he remains oblivious to the ultimate truth: Isolde isn't a substitute at all—she is the girl who saved him from the fire fifteen years ago, and Lina is an imposter.
