Become the Regent's Treasure

Drunk after graduation, I traveled to a new time and space. It turns out that my father is the emperor and my mother is the concubine. They have thought about a good life in the future, waiting for death and sitting in vain. As a result, neighboring countries came over, and Dad decisively sent her as a hostage. The little prince of Fujian: "Little fairy, my birthday is tomorrow. Will you come to my birthday dinner?" The Seventh Prince of North Country: "No." The young prince of Fujian was furious: "I didn't ask you!" The Seventh Prince of North Country: "I am her fiancé and have the right to make her decision." The useless and incompetent little princess meets the seventh prince of the North Kingdom in a foreign country. What kind of sparks can the two create?
