Since Yin's generation, for more than 200 years, the nursery rhyme "Queens all speak of their own family" has been circulating among the people. Yan Wan, as the chosen future queen of this generation of the Yan family, is calm, wise, beautiful but not enchanting, and has little reputation. As the last training before getting married, Yan Wan was sent to the Xiao family in Lin'an, known as the "Prince in Purple Clothes", to receive the oldest and most orthodox etiquette training, with the hope of joining the palace to assist the emperor and become a virtuous queen comparable to the founding empress.
There, young Yan Wan met her fate - Xiao Bai, the Marquis of Lin'an. Even though she admired him wholeheartedly, she knew her responsibility and mission well, so she didn't deliberately approach him. She just stared at that person silently with a faint appreciation and affection.
The one-year training period has expired, and Yan Wan returns to the imperial capital Chang'an under the escort of Xiao Bai. On the way back, the team was unexpectedly intercepted and killed, and all the servants died. Only Yanbai and the others survived. The two went through many hardships and finally returned to the imperial capital. However, Yan Wan, who was originally prepared to marry into the emperor's family and then die of old age in the palace, unexpectedly encountered the rejection of the marriage by her childhood sweetheart, the prince's cousin, who was interested in someone else.
Standing at the crossroads of marriage, where should Yan Wan go? Should she overcome all difficulties and forcefully marry her rich and handsome cousin, or should she take advantage of this opportunity to remarry her lover, the young marquis?
