Guess wont be seeing him until… (25 months and 6 weeks later) mid-2011 ?
Brief news translated from various sources:
He will be in basic army training for 6 weeks and will serve the airforce (in Chinese – 空军军乐队) for 25 months.
He is the first artist to join the airforce.
Other artists that will join the army (not necessarily the airforce) in the later half of the year are Lee Dong Gun (confirmed to be sometime in May), Kim Rae Won and Lee Jin Wook.
