Tan Jia is totally into this stuff. His family's well-off, and they've got their own wine cellar full of his collection. If it's not good wine, he won't touch it, but Xiyuan's wines, no question, once he tries them, he'll love them. However, Tan Jia has no idea if they're even available here, so he doesn't ask—he's worried it'll be awkward if they don't have any. Luckily, Pei Ziyu knows him well, so he just gives him a straight answer.
Fan Tianyu noticed the speaker was someone unfamiliar, so he quickly asked, "And you are...?"
Pei Ziyu introduced him, "This is my law firm partner, Tan Jia. And this is Zhenzhen's cousin, Fan Tianyu—he's also the boss of Xiyuan."
The two exchanged polite greetings, and Mei Mengzhen chimed in, "Brother Tianyu, have you eaten? Join us."
Honestly, none of the three had anything really urgent to do. They used to eat with classmates, so today's no different.
