Influenced by her father, Yu Aizhen has been more like a boy since she was a child, with a very bold personality, and her favorite thing to do is for women to dress up as men and go in and out of various places. Over time, she became acquainted with many gangsters, and under the recommendation of these people, the rogue leader Ji Yunqing also met Yu Aizhen. When he saw this girl, he grinned and liked it very much, so he accepted Yu Aizhen as a righteous daughter.
