The heroine, Shen Yiyi, was originally the heiress of the Shen family. Her mother spent her pregnancy in the countryside to enjoy the fresh air, where a maid's younger sister gave birth out of wedlock. Hoping to give her niece a life of privilege, the sister secretly switched the babies. But the maid's sister had no love for childcare and left the baby at the doorstep of the Lu family, who happened to be vacationing in the countryside. And so the Lu family gained a younger daughter. Years later, the real and fake heiresses meet in the capital. They attend the same university, Beijing University, and study the same major. They both like Hua Yinan. The Shen parents assume Lu Yiyi has no one to rely on, and, after being deceived by Shen Jia time and again, they berate her mercilessly.
