Ningcheng's richest man, Lu Yongnian, although already extremely wealthy, still has a regret. Since his first wife Shen Rong cannot bear children, Lu Yongnian placed his hopes on his second wife Wei Yixian. Wei Yixian did not fail to meet expectations and bore the Lu family a baby girl named "Lu Mingzhu".
Shen Rong, though she had adopted a son "Haozhong", he was not of the Lu family bloodline. Thinking about the future, she felt fear.
Blinded by jealousy, she took advantage of Lu Yongnian being away on business and claimed that Wei Yixian had contracted leprosy. She locked Yixian and her daughter in the woodshed. Her trusted steward Qian ordered the woodshed to be set on fire. At the critical moment, Aunt He managed to save "Mingzhu" but unfortunately fell into the valley while escaping, with no sign of survival.
After Lu Yongnian returned home, he was heartbroken. And Wei Yixian, having suffered excessive shock, became mentally confused, starting her long tragic years.
Eighteen Years Later
Aunt He changed her surname to Zhao, becoming the daughter Yun'er of Mama Zhao, "Lu Mingzhu". Along with her father Cheng Yong, sister Tongxi, and master Li Jun, they settled in Ningcheng. They also befriended Gu Yueyue, the daughter of the "Gu Family Business" who had an engagement with the Lu family.
On the wedding day, Yueyue, who already had a lover, suddenly fled the marriage. Yun'er temporarily replaced Yueyue and entered the Lu family, getting married to Lu Haozhong. However, Yueyue never showed up, and it was discovered that Yun'er was impersonating her. But Haozhong couldn't help falling in love with Yun'er and insisted on marrying none other than Yun'er.
Shen Rong, seeing Yun'er who looked very similar to Wei Yixian, developed an inexplicable sense of fear. Thus, she tried every method to obstruct the wedding. On the contrary, Lu Yongnian had an inexplicable liking for Yun'er and accepted her as the daughter-in-law of the Lu family, disregarding any class distinctions.
