On their wedding night, Prince of Zhenbei Chu Zhaoling abandons Shen Yuan for his moonlight, Su Wanqing, and rushes off to the border. Heartbroken, Shen Yuan writes a letter of divorce. On the street, she rescues the heavily injured handsome Xiao Yan and keeps him by her side, unaware that he is Prince Jing'an Chu Yan, who faked his death, went undercover, and has spent three years searching desperately for her. Su Wanqing repeatedly frames and spreads rumors about her, leaving Chu Zhaoling full of bitter regret when he learns the truth, after which he aggressively tries to force her back to the estate. Relying on her wits, Shen Yuan tears apart the green tea and punctures the conspiracy, successfully obtaining a divorce under Xiao Yan's deep, devoted protection, and ultimately marrying Prince Jing'an for a happy and complete romance.
