After releasing the MV and collaborative single Nagging earlier this month, the Seulong and IU powerhouse duo have managed to nab the number one position on this week's Gaon Singles Chart. The duo managed to climb up 11 spots and pushed out 3 week chart toppers the Wonder Girls. Due to this sudden and huge move for Nagging, CNBLUE's Love has also been pushed down from the 2nd position to 3rd. Congrats to this duo for their success!
