In his previous life, Song Wan abided by etiquette and kept the festival for six years for his fiancé who "died in battle". However, when he "resurrected" with his time-travelling girl, he was slandered as an unfaithful man and died with hatred. Reborn into her third year as a widow, she is determined to tear apart the hypocritical ethics and no longer be a pawn at the mercy of others.
In this life, the dilemma she faces is: continue to play the role of a docile legitimate daughter to protect the family, or break free from the shackles and seek revenge on the man and woman who ruined her life? Choosing the latter means being an enemy of the entire secular etiquette and may lead to ruin.
The turning point in fate lies with Prince Shen Qianyu. This prince, who had been a hostage to an enemy country and had gone through many hardships, saw through her pretense and tenacity. When his fiancé and the time-traveling girl used their "prophet" to stir up trouble in the court and plot evil, Song Wan and Shen Qianyu formed an alliance. She used the memories of her past life to maneuver around the house and the palace, breaking conspiracies and gathering people's hearts; he defended the enemy on the front line and quelled the turmoil caused by the time-traveling woman's attempt to change history.
Their feelings grew while fighting side by side, but between Song Wan's identity as a "widow" and Shen Qianyu's position as prince, once the fatal secrets of emotion and power were exposed, it would lead to disaster. In the end, the two worked together to resolve the chaos. Shen Qianyu ascended the throne as emperor, with the country as his retainer, and Song Wan, who had experienced nirvana, as his queen, and jointly created the prosperous Qingming era.
