I was so happy to see shin hye with one of her CN blue buddies (JongHyun), last time it was with Minhyuk at the airport. And I'm pretty sure she congratulated or said hi to Jungshin at the backstage or dressing room.
There are so many talks going around, that makes me wonder why yonghwa and shin hye tried their best not to be seen in the public eye and avoided each other if possible. It just shows even more that there might be something going on between them. When they mention YH's name in interviews and such, I feel like she would try her best to derail the subject and YH would turn red if her name came up. She was OK working with other male artists without the Korean paparazzi linking them, if she would ever work again with YH I'm pretty sure it would cause havoc on both fans and antis, and whatever was blossoming between them has come to halt.
I'm her fan first before I came to like YH and cn blue...and I had shipped her with anyone she had great chemistry with, but theres really something about yongshin that stands out.
