Shen Qingyin was ordered to paint a portrait of Prince Huai Xiao Jinyan, but she discovered in her brush strokes that this prince, who was rumored to be as gentle as jade, was inextricably linked to the mystery of her family's annihilation. While secretly investigating, she continued to draw portraits, but as she got along with him day by day, she was moved by Xiao Jinyan's tenderness and respect, and her guard gradually collapsed, until she found key evidence in the secret room of the palace, confirming that Xiao Jinyan was the one who ordered the seizure of Shen's house. Shen Qingyin was determined to assassinate her, but she learned the truth on the eve of the assassination - Xiao Jinyan had tried his best to save her life, and there was a black hand behind the murder. At this time, the real murderer had set up a trap to frame her for treason. In order to protect her, Xiao Jinyan had to send her to the prison with his own hands, but he left a letter in prison confessing his feelings and willing to trade the throne for her safety. Shen Qingyin finally understood his forbearance and affection. In the end, Shen Qingyin used her painting skills to expose the real murderer's conspiracy, but Xiao Jinyan was in danger of blocking a poisonous arrow for her. Shen Qingyin used her body as a guide and used the family's secret detoxification method to save him. The two went into seclusion hand in hand. Only then did she understand that true love is not revenge, but mutual fulfillment and trust.
