The tickets for JYJ member Jaejoong’s upcoming concerts in Seoul sold out within five minutes of going on sale, his label C-Jes Entertainment said Thursday. The first round of tickets for the concerts, titled “The Beginning of the End,” which went on sale at 8 p.m. on Wednesday, were quickly snapped by those who wanted to capture Jaejoong’s last moment onstage before he joins the Army. The concerts, at Korea University in Seoul on March 28-29, will mark his last event before he enlists for mandatory military service on March 31. The second batch of tickets can be purchased on online booking site Interpark from 8 p.m. on Friday. The 29-year-old idol will enjoy his time with fans and family before enlistment after wrapping up his fan meeting schedule and filming for the KBS drama “Spy.”
