The Foolish Prince and His Cool, Beautiful Consort

A car accident transmigrates her into the body of a concubine-born daughter of a military family. From then on, she is no longer a meek young lady whom anyone can bully. She fights back from the brink, reveals her brilliance, and wins everyone's hearts. In public, the Seventh Prince acts like a foolish madman, but in private, he's cunning and brilliant. He marries her with ulterior motives, only to fall in love with her without realizing it. The supremely noble Crown Prince will stop at nothing to claim the throne, yet shows tenderness only to her. After a thousand years of transmigration, who was she destined to come for?
