Su Qingwan, a modern history student, unexpectedly finds her soul transported into an ancient romance novel, where she becomes an abandoned concubine in the cold palace who won't survive past chapter three. She is also bound to a “favorability-for-skills” System. Her starting favorability is zero, and her scores with the emperor, the prince, and the general are even in the negatives, leaving her in a dire predicament.
To protect herself, she uses the System's beginner skills to turn things around: she uses basic medical knowledge to save Emperor Xiao Jingyuan from acute poisoning, draws on her connections to find rare medicinal ingredients for Prince Xiao Jingran's mother, and treats General Lu Zhanting's old injuries with medicine for external wounds. Not only does she unlock benefits such as court connections and supplies, but the powerful officials who were once indifferent to her all fall for her, kicking off a “everyone competes for her favor” mode. Unlike heroines in traditional palace-intrigue stories, Su Qingwan refuses to compete with the other consorts. Instead, she uses skills such as antidote-making and lightness kung fu to help them solve their problems. Even the original heroine, Empress Shen Mingyue, becomes her “wingwoman,” while the Empress Dowager takes the initiative to mediate the love triangle among the male leads. There's no angst, just sweetness all the way.
As the story unfolds, she helps Xiao Jingyuan thwart a poisoning plot at a palace banquet and put down a rebellion by political enemies. She helps Xiao Jingran give up his claim to the throne and focus on protecting her, while Lu Zhanting chooses to remain in the capital by her side. She also makes a pact of secrecy with Imperial Physician Xie Yunshu, who has likewise transmigrated into a book. In the end, Su Qingwan rises from an abandoned concubine in the cold palace to the Consort Chen, entrusted with helping manage the imperial harem. When faced with the System's ultimate choice of love, she can either build a deep bond as emperor and empress with the male lead she loves, or choose an open ending in which everyone protects her. She also receives a reward from the System: the ability to travel freely between the modern and ancient worlds, achieving a truly mutual and happy ending. The novel features interactive plot branches decided by reader votes, blending sweet romance with satisfying wish fulfillment in an inventive take on the transmigration-into-a-book genre.
