**Three years of devotion. Three years of playing the perfect, submissive girlfriend. And for what? To find out she was nothing more than a placeholder.** Ruan Chutang lived a lie in Haicheng, trading her life as a billionaire heiress for a modest job as a lawyer, all to stay by Gu Zechuan’s side. She thought they were building a future. She didn't mind his coldness or his demanding mother—until the night his "White Moonlight," the one who got away, returned to claim her throne. Standing in the shadows, Chutang hears the devastating truth from Zechuan’s own lips: *“She’s just a substitute. I’ve spent every day looking for Chen Wan’s shadow in her.”* Done with being a shadow, Chutang doesn't cry. She doesn't beg. She makes one phone call: *"Dad, I’m coming home. I’ll marry whoever you want."* Back in Jiangcheng, the "poor little lawyer" vanishes, and the crown princess of the Ruan empire returns. Waiting for her is Jiang Shixu—the cold, powerful heir to the Jiang conglomerate and the man she was always meant to wed. He’s been waiting years for her to look his way, and now that she’s back, he has no intention of letting her go. But when Gu Zechuan realizes the "obedient" girl he threw away is actually the untouchable socialite he desperately needs to save his failing business, he comes crawling back. Too late. The substitute is now a queen, and her new King doesn't share. **He thought she was a glass trinket he could break and replace. He’s about to learn she’s a diamond—and she’s far too sharp for him to handle.**
