Yan Qiujue traveled through time and became the "princess" of the Yan Kingdom, a princess who disguised herself as a woman. Just when he was about to despair of this world, he realized that he had traveled through time and entered a romantic novel about strong women called "XX".
His future "husband" will be the heroine disguised as a man. (Haha, I thought Yan Qiu Jue and the heroine were a perfect match. Don't be kidding. This is a beautiful article.) And he, Yan Qiu Jue, was just a male N number with the name of the heroine's wife. He was the catalyst for the relationship between the heroine and the male protagonists. In the end, he fell in love with the heroine and even gave his life.
Knowing the truth, he decided to become a hermit (gay) and change his destiny.
