Ye Kun invited the Shi brothers to dinner and repeatedly stressed that they had to bring their wives along because he got himself a girlfriend and wanted to introduce them to each other.
Shi Ke always treated his younger brother's close friends equally well. When he heard Ye Kun finally had a girlfriend, he sang Ye Kun all sorts of praises before his girlfriend. He was like a salesman, trying his best to introduce Ye Kun's strengths.
Ye Kun was very thankful for that. He was also extremely grateful to Shi Nian. If Shi Nian hadn't rented the apartment to him, he wouldn't have had this opportunity to get so close to Fang Xi.
Only then did Fang Xi and Yun Nan know that Shi Nian and Ye Kun were actually good buddies, and only then did Ye Kun and the Shi brothers know that Xiang Yang, Yun Nan, and Fang Xi had long been good friends.
