It was reported yesterday that 2AM member Seulong and solo artist IU would be collaborating for a second We Fell in Love track titled Nagging. A day has passed and the MV teaser for the track has been released. In the short 19 second teaser, the two artists are seen recording the song whilst fooling around behind the scenes. Though no word has been set about these two being another couple for We Got Married, the two definitely seem to have some cute chemistry going on! Keep your fingers crossed while you check out the video below! Stay tuned to allkpop for the full MV!
