It was revealed today that After School member, Yoo So Young (23) had fainted on the morning of 18th April due to fatique and overwork. So Young was subsequently hospitalized for treatment and observation. That was the reason why you only saw 5 members of After School performing Diva on MBC Show! Music Core this afternoon. After School had made their comeback a week ago with their latest single Diva and begun their busy broadcast schedule. In addition to performing, the After School members have been putting in at least 3 - 4 hours of training daily so that their performance can be as perfect as possible. But as always in such cases, Yoo So Young will make a speedy recovery with a full day of rest and rejoin her members tomorrow afternoon for their SBS Inkigayo performance. During a recent Music Bank performance, After School did a shortened version of Diva and Park Ga Hee made a mistake of singing the chorus at 1:46 which had been present originally. Was there really a need to cut the song which wasn't that long to begin with? Anyway, the mistake sounded cute and we know that they sang it live. Hopefully, everything will be fine on SBS Inkigayo tomorrow afternoon to close out the week. many thanks to Timo, mia and engl for tip.
