Known as Kara's member, Kang Ji Young's cousin, 21-year old NS Yoon Ji made her official debut on 24th September, with the release of her MV for her title song, "Headache". She also made her debut stage performance on Mnet's M! Countdown tonight. Bravely debuting as a solo singer, NS (New Star) Yoon Ji will definitely need a lot of luck to stand out from the horde of girl groups and returning male singers. The song does not seem that great although the dancing is pretty decent. What do you think? The MV. Many thanks to lindy for tip and SMarie7, Katana for videos.
