Chen Yuan, a graduate student in modern psychology, experienced his first time travel to the era of Wang Yangming of the Ming Dynasty. He accidentally fell into the Northern Song Dynasty five hundred years later in the turbulence of time and space, and possessed the body of "Qiao Xiaoxin", the personal maid of Li Yu, the queen of the Southern Tang Dynasty. However, the original owner of this body was actually the third princess of the Southern Tang Dynasty who kept her name anonymous to avoid disaster.
Waking up in the desolate courtyard where Li Yu was imprisoned, Qiao Xiaoxin faced the subjugated king who wrote his lyrics in tears and wore ragged clothes. The sadness of "crying for the palace concubines" in the history books turned into real trembling and despair before my eyes. When Li Yu was overjoyed by the visit of his old minister Xu Xuan and expressed regret, Qiao Xiaoxin, who was familiar with history, understood that this was a fatal temptation - tomorrow's Chinese Valentine's Day, Li Yu's birthday, would be the fatal moment recorded in history books.
Seeing the completion of the last words of "Poppy Poppy", the murderous intention is coming. Holding the knife hidden by the original owner, and carrying the memory and wisdom of two lives, can Qiao Xiaoxin find a glimmer of hope for this fatal dilemma at this last moment?
