2AM's Jo Kwon and Brown Eyed Girls' Ga-In have a special surprise in store for the Adam Couple fans. The cute on-screen couple will stage a duet performance for the Brand New Concert, which will unfold on the 20th at the JamSil Stadium. They will be performing a summer version of their smashing collaboration, We Fell in Love. Their track has been receiving lots of love, particularly because both Jo Kwon and Ga-In took part in the song-making process through MBC's We Got Married. Various groups, such as 2AM, Brown Eyed Girls, BEAST, KARA, and T-ara are going to perform for the Brand New Concert as well.
