Qing Yuzhen, the legitimate daughter of the Hou family, married Meng Yanzhi, the new champion scholar, out of love. During her pregnancy, when she thought love and life were both perfect, she unexpectedly discovered that her husband had already made a lifelong commitment to her concubine Qing Yuwan. What's even more cruel is that this marriage was a careful calculation from the beginning - using her status as a legitimate daughter to pave the way for Meng Yanzhi, and then using her belly to give birth to a child for the frail Yuwan. Everyone treats her as a tool, but she is still immersed in the dream of a good match.
