Yup, among all the stars from Thailand, Vill will be the only girl.
Not much to update: I'm not sure whether or not Vill's fan club in China (China Vill Club) had contacted Khun Kate directly, but their Weibo did say that she confirmed Vill is to show up in the Beijing activity on 31 March 2016 and that they will keep monitoring the disclosure of further information. That is, pretty much like the message posted days ago by Son's Chinese fan club. I scanned through discussion threads in baidu forums. Some fans did say, if possible and probable, they are more than willing to meet and greet Vill and Khun Kate in Beijing. But a few problems exist: 1. That is not a holiday in China, which means they may need their teachers/bosses to accept their requests for leave of absence; 2. Many fans lived in other cities and would need to book a flight and hotel in advance, which could mean a big money; 3. It may very likely be an event not open for fans to take part. So, to go or not to go, that is a tough question now bothering some of Vill's fans in China.
