US5怎么只有4个人了

因为Chris同学貌似退出了，好像身体不太好，这是在吧里找到的chris同学的原话：
My mental health & phisical is on the edge,for the last few months I wasn't happy! I can't get out of bed,I don't have strenght for it..My dreams started to fall a part a year ago...Stressfull days,shows,fans,media...
I don't have real friends,girlfried,love! Suddenly I had only one part to play....
I didn't have anyone to talk to,to open to that person...I went to psychiatrist..
It was hard to admit to myself that I can't do it anymore...The doctor said to me to get out now...I'm so sorry for the fans & boys from the band,but my health is on first place.The last show with US5 was in Düsseldorf & after the show I collapsed in the wardrobe...Then I relased..It's over...I'm never going to do music
所以说视频里只有四个人，不过现在又加入了一个，具体的你可以去us5的贴吧还有他们的官网看看。
