Five years ago, Gu Chenshi fell victim to a drugging incident, resulting in a one-night stand with Song Siqing. This liaison led to Song Siqing's pregnancy and the subsequent birth of a child. Unfortunately, Song Siqing's stepmother, Wang Ping, callously discarded the newborn. In a stroke of fate, Gu Chenshi ended up adopting the child. For five years, Song Siqing tirelessly searched for her lost child, but her efforts were in vain. It wasn't until a encounter at the kindergarten entrance that Song Siqing was reunited with her child, Gu Yueni. Compelled by her half-sister's actions, Song Siqing was forced to marry into the Song family. Amidst a series of entanglements between the Song and Gu families, the truth slowly comes to light.
