The video is about them having fun in same sort of camp and well, live while they're young. The song is catchy and fun like the summer anthem and the the images are beautiful and vivid. Supposedly, they will lead the video around October but somehow have to show it early as the video leaked online. I do watch the "illegal leaked". Sorry boys.
So far the video has over 14 millions view on YouTube since 2 days ago and I think I do contribute around 10 of the views.
So here is the video, let's go crazy crazy crazy for this video!
P/s: About Zayn cute and hot thing, please go to 1:42, 2:05 and 2:13 of the video
