Actually, Emperor Zongwen did not want his Fifth Princess to marry Bai Yichen. She had been by his side for many years and was the daughter of the Empress, which naturally meant that she should be used to maximize the interest of herself and the imperial family. If she was to marry, she should definitely marry Bai Yihao, the Crown Prince. The two families were relatives, to begin with, and the marriage between two cousins would naturally strengthen the relations between the two families. When the next Crown Prince of Yan Kingdom was born, his bloodline would be closer to the Qin Kingdom, greatly benefiting the Qin Kingdom.
