After Gu Yunzhi killed herself in the 21st century, she transmigrated into the heroine of a book she had read in elementary school, set in ancient times. Though her memories were hazy, she already knew the story and its ending. Determined to change that ending, she decided to help the benevolent Second Prince ascend the throne.
After earning money by making cosmetics, Gu Yunzhi began building connections. Around the same time, she met Jiang Ziluo, the male lead, who had returned from the frontier with her eldest brother. After her younger sister and a concubine plotted against them, she and Jiang Ziluo ended up together, tying their fates in a knot that could not be undone...
By then, Gu Yunzhi realized that events were not unfolding exactly as the book had described. She had become a variable in the story, and its plot was changing accordingly...
At a state banquet, Gu Yunzhi successfully met the Second Prince and managed to earn his complete trust. Just when she thought everything was going smoothly, she was kidnapped... The truth became increasingly elusive.
