The ending of the original book is that if Bai gives birth to a girl named Beibei, who is also a taekwondo master, Xiaoying and she are married, but they have never had children. Chu Yuan went abroad and didn't get married, so it seems that she doesn't have a girlfriend (I don't know if it's true that she finally said she has a girlfriend, but Xiaoying is also skeptical, so she's not sure).
