2AM's Seulong and IU's duet song "Nagging" won Mutizen in Inkigayo last weekend. I find the song cute and refreshing that's why I'm glad that they won. =) It's talented IU's very first time to win in a music show since her debut and you can see the surprise in her face. Congratulations! ^^
My favorite live performance they did by far is the one from Music Core. They're really cute! ^^
