Were Ayu and Shu-ya crying @ AT 07?

[waterballoon]

It could be sweat, but I don't know how a sweat drop can come from an eye. And it's not like Shu-ya cries at every single upsetting song...

I feel so off-topic now but do you guys notice that Shu-ya is usually isolated and alone in the documentaries? Like Zin and Go-Mi and the other guys would be chatting or talking to Ayu and Shu-ya would just be sitting alone, spacing out. Hmm...
