After Becoming the Villain's Concubine-Born Daughter, I Was Doted on by the Heir

Shen Yan, a modern graduate student in history, transmigrates into a book as Shen Yan, a concubine-born daughter of the Marquis of Dingbei's household in Great Chu. The original Shen Yan, jealous of her legitimate elder sister's engagement to the heir of the Prince of Dingbei, schemes to frame her sister and ends up exiled and dead. After her memories awaken, Shen Yan tries to save herself by avoiding the original plot, only to unexpectedly attract the attention of the heir, Xiao Chengyu. When Cai Ling, the green-tea-style villain from the original book and a maid accompanying Shen Yan's elder sister, provokes and frames her, Shen Yan responds with cool-headed reason. As she investigates the original Shen Yan's wrongful accusation and resolves her family's crisis, she and Xiao Chengyu go from warily testing each other to falling for one another. In the end, she changes her fate, finds a sweet and loving ending, and uncovers a hidden piece of history tied to the founding of Great Chu.
