The queen's niece Shen Qingyuan was mistakenly infatuated with the second prince Xiao Jingyun in her previous life. She was deceived by his love and became a tool to frame the prince Xiao Jingsi. She helped Xiao Jingyun steal secrets and slander the prince. However, after Xiao Jingyun seized power, she was stigmatized and thrown into a brothel. She was betrayed by her best friend Lin Wanrou and died in a sea of fire.
With endless regret, Shen Qingyuan was reborn at the age of 16, just before the tragedy began. In this life, she suddenly woke up and determined to protect Xiao Jingsi and atone for the sins of her previous life. She took the initiative to get close to Xiao Jingsi, who had been left out by her, and used her past life memories to expose Xiao Jingyun's conspiracy, helping the prince resolve the crisis and stabilize his position.
From his initial doubts, Xiao Jingsi was gradually moved by her intelligence and sincerity. His deep love was rekindled and he doted on her. Facing the counterattack of Xiao Jingyun and Lin Wanrou, Shen Qingyuan joined hands with Xiao Jingsi to collect evidence to completely bring down the two of them and ruin their reputation.
In the end, Shen Qingyuan was canonized as the crown prince and had children with Xiao Jingsi. When Xiao Jingsi ascended the throne and became the emperor, she also became the queen. The two of them built a prosperous age together and fulfilled the life they missed in the previous life.
