With new member Seo Eun Gyo in tow, Co-Ed's new female sub-group, 5dolls, continued with their 2nd debut stage through KBS's Music Bank on February 18th. The girls have certainly attracted a lot of attention ahead of their comeback after Jay Park starred in two of their music videos, but now it's time for the girls to do it on their own stage. And in what seems to be a norm these days, the girls will be promoting one of their two title tracks, 'I Mean You,' which combine a strong guitar sound, addictive bass, and synth by Jo Young Su, as well as a strong beat, heavy drums, and electric piano sounds from Brave Brothers. Check out their performance below!
