Although not as nearly as successful as the previous version by Jo Kwon and Ga-In, 2AM's Seulong and IU's duet track Nagging has gained quite the fame nonetheless. The attractive harmony of the two brought fans' high-demands, wanting for the couple to bring the track onto an official stage. However, due to various scheduling conflicts (as IU still attends high school), seeing the two on stage together seemed almost impossible. Luckily, it's been announced today that Seulong and IU will have a duet performance much soon on a music program. The official date of the stage hasn't been announced yet, but it's guaranteed to be within a few weeks from now. According to IU's agency, the scheduling is still an issue, but they are putting their efforts to find a solution together with Seulong's agency for the fans. So we just need to wait now.
