Have you all seen NU'EST's MV for Hello? If not....WATCH IT NOW~

And Sandeul from B1A4 had to undergo surgery in his knee because of an injury to his meniscus. He's recovering now but he'll have problems performing on stage for the time being. I wonder who in B1A4 will get surgery next.... :( It was Gongchan last time and now Sandeul.
