Ga In may be promoting as a solo artist once again, making fans wonder with a touch of sadness when Brown Eyed Girls will be making a comeback as a group, but she still has tight friendships with the other members as seen on the March 16 installment of KBS coolFM's 'Jang Dong Min and Lady Jane's 2 O'Clock.'

Ga In said, "I think jealousy is a good stimulus. �It is a time when we need something like this. �All of us work hard. �When I see Narsha on variety programs, I think to myself, 'I need to be more diligent on varieties.'"
