Mu Wan, the legitimate daughter of the Prince of Zhennan's household, trusted the wrong people in her previous life. To marry the Eighth Prince, Situ Che, she even knelt and pressured her betrothed, Crown Prince Situ Jue, to break off their engagement. To grant her wish, Situ Jue volunteered to guard the frontier and did not return for three years. Little did she know that Situ Che only wanted the Mu family's military power. Once he had it, he framed the entire Prince of Zhennan's household, then dragged Mu Wan into an ice cellar in the dead of winter and tortured her to death.
Only as she lay dying did Mu Wan learn that Situ Jue was nothing like the cold, abstinent man described in the rumors. He had endured in silence for years, protecting her from afar, and had even remained unmarried for her sake. When he learned of her brutal death, he slaughtered her enemies and followed her into death.
Burdened by boundless regret, Mu Wan was reborn at the age of fifteen. This time, she would tear apart the treacherous man and his vile companion, protect her family at all costs, and win back the Crown Prince whose heart she had broken. Faced with her sudden show of affection, Situ Jue was deeply suspicious. He thought it was another one of her schemes and repeatedly tried to avoid her.
From testing one another to speaking honestly, from misunderstanding to deep affection, they came to understand each other's feelings through their many clashes. Situ Che, who finally saw the truth but let love turn to hatred, tried to harm Situ Jue and ultimately met a miserable end. This time, Mu Wan and Situ Jue would never miss their chance. They would grow old together, hand in hand, and protect their homeland side by side.
