Papa Chi looked at the couple and said, "Yes, he did and they're twins, all boys. We're trying to find their father, which is why we wanted to meet you and ask if perhaps you might know him or could make any guesses?"
The Yuns couple were happy to know that not only are they grandparents but they have two at once. They could not hide their joy even with the impending problem of their unknown father. They wanted to meet their grandkids immediately.
Mama Yun decided to answer the question when her excitement stabled. "Our Yun Lui was not very friendly towards a lot of people so he had no friends except for the last child of our friends whom you've already met."
"The one called Xu An?", Mama Chi asked to confirm and Yun Lui's mother nodded to that.
"Okay. He also mentioned that they were best friends when he visited him here.", she said and turned to her husband, "Honey, I think we should invite that young man for a talk too."
