Answer to why only Wang Zi in 星之國際

Every since that news/video of Wang Zi and 星之國際 artist attended a press conference I'm sure every fans is curious why out of Lollipop there's only Wang Zi and scared that Wang Zi might drift off his own way.

But thanks to Andy we have the answer. Simply it's just that before entering BBT Wang Zi was ready signed under 星之國際, that is why they have a very old photo of Wang Zi on their website. And how I thought Wang Zi was just an ordinary student with good grades.
