Shen Ying, Princess of Yongning Commandery, once devoted herself wholeheartedly to protecting the Thirteenth Prince, Xiao Heng. But at the husband-selection banquet, she finally saw his selfish true nature and calmly let go of the love she had mistakenly given him for ten years. Following the rules, she sent the two of them far away to the northern frontier before setting off herself to gain experience and grow at the border. There, she encountered Wen Ce, heir to the Prince of Huai'an, who had secretly cherished her for many years. Together, they resisted foreign enemies, supported one another, and pursued their mutual love, finding understanding and companionship amid the flames of war. Upon returning to the capital, they joined forces to quell political turmoil, secure the realm, and properly settle the affairs of the past. After their wedding, they left the political struggles behind and traveled the world together, eliminating corrupt officials and rebel bandits along the way while protecting the local people. Shen Ying finally broke free from the shackles of romantic love and found a soulmate who truly understood her.
