Su Ningwan, the legitimate daughter of the Grand Tutor, is a notorious spoiled troublemaker in the capital. Forced by imperial decree to marry the dissolute Third Prince Pei Yan, she originally planned to use all sorts of torment to drive him toward ambition, intending to walk away freely with her rewards once successful. One night, she accidentally overhears her husband's inner thoughts, catching his declaration of 'rebirth and revenge,' accompanied by a macho protagonist system egging him on to conquer the realm. Terrified, she seeks out a divorce letter overnight and flees far away to Jiangnan. Little does she expect that Pei Yan would chase after her despite his injuries, staging an amnesiac self-torture scheme. Through several rounds of tension, the truth is finally revealed: from beginning to end, it was all a tender, hidden crush kept secret for many years.
