Who is Su Jianxin's wife?

Su Jianxin has never been married, but she and Zhang Yuhuang (now married, with a basketball player) have a daughter, formerly known as Su Jie, who is called "Little Maruko". Now Su Jianxin lives with Maruko and his parents. I have a girlfriend who has been together for seven years. She said many times that she would give her a birthright, that is, she would get married, but she also said that she would not get married until Maruko became an adult, and the new mother must be liked by her daughter.
