Su Wan crosses into the historical angst novel she wrote, becoming Shen Wanqing, the female lead destined for a tragic end. Facing the cold-violent Fourth Prince and the scheming concubine from the original book, Su Wan changes the plot instead of her character setup. Using modern common sense and sharp-tongued sarcasm, she defuses bullying and breaks the formula of "angst." From mutual probing with the prince to building trust, she displays her wisdom while investigating the noble consort's framing case and the assassin crisis, eventually confessing the truth about crossing into the book to the prince. Together, they shatter the original book's tragic destiny, moving from resistance and backtalk to a proactive confession, and finally achieving a HE ending through the Empress Dowager's bestowed marriage, rewriting the story from tragedy to comedy.
