The eldest princess Yun Qi unexpectedly travels into a storybook, becoming a false daughter of a marquis manor with a tragic fate. The original owner had her background exposed, was cast aside in divorce by General Huo Xiao, and would later be discarded unceremoniously at a mass burial ground. Unwilling to repeat the same tragic end, Yun Qi navigates with wisdom between the marquis household and powerful nobles, countering the schemes of Yun Xiyue, the original story's heroine. She unravels crises step by step, rewrites the destined tragic fate, and carves out a life of her own amid the strife between the imperial court and noble families.
