During an earthquake, Wen Yitang, a shepherd girl, risks her life to rescue Pei Jingshan. A maple-leaf-shaped birthmark unexpectedly reveals the secret behind the true and fake heiresses. Her sudden entry into a wealthy family brings hidden currents and turmoil. The impostor heiress repeatedly schemes to frame her, while one crisis after another strikes, from being trapped in a cold storage facility to a shortage of materials. Wen Yitang refuses to back down, overcoming every obstacle with the courage and resilience she developed in the mountains. Rather than relying on the privilege of her newfound identity, she works diligently and steadily grows into an independent project manager. At last, the family bonds that had been misplaced are restored. She stays true to herself, builds an independent career, and finally receives the unwavering affection of Huo Yunchen.
