After making her solo debut in October, Ga-In has definitely made an impression with her title track, "Irreversible", culminating in her claiming top spots on numerous online music charts. It took her a while, but she finally claimed the Mutizen award on Inkigayo two weeks ago, which was really the icing on the cake, including a present from her "husband" Jo Kwon. Since that win though, Ga-In has seemingly quietly ended her promotions, as she is now focusing entirely on her acting career for the MBC daily sitcom, "All My Love." But in view of doing charity for a good cause, and to say a proper goodbye to her fans who have supported her, Ga-In appeared this afternoon for her final "Irreversible" performance. Check it out! Technically, it's Inkigayo, but "2010 Love Sharing Concert" is just taking its place this week.
