In order to help the prince's cousin Xiao Jinchen to relieve the disaster, Gu Xiyuan donated 200,000 taels of silver in exchange for his promise to be the "only prince concubine". Unexpectedly, when he returned from his triumph, he joined forces with his father to take away all the titles of county lord and crown princess that belonged to her and gave them to his concubine. After being wronged sincerely and being stabbed in the family's back, Gu Xiyuan suddenly realized that she no longer wanted to be the legitimate daughter who swallowed her anger. She vacated the palace, kicked out the scumbag, helped her mother reconcile, and even offered a job of ten thousand taels of gold to buy the position of princess from the cold-faced King of Yan, Xiao Xun. From then on, she held her business line in hand and worked step by step, vowing to make everyone who betrayed her regret their mistakes!
