Shen Qingwan and her sister Shen Qingmei married the Yun brothers. The eldest Yun died protecting Yun Yichuan, so the elders pressured Yun to unite both households to preserve the main lineage. He publicly refused but secretly did IVF with both wives without their knowledge. When Shen Qingwan found out, she divorced and left. Overwhelmed with remorse, Yun chased her across thousands of miles, punished the elders who harmed her, but failed to win her forgiveness. Desperate, he imprisoned her—luckily, her childhood sweetheart Gu Xiaolang helped her escape. Eventually, Yun realized his mistakes were irreparable, and Shen Qingwan let go of the past, starting a new life hand in hand with Gu.
