Altough I might be a little late with the G★Star coverage (student life ftw), I think most of us have waited for photos of MaMi and here they are ^^ She is looking gorgeous as usuall and is representing Sega, most likely for a sportgame. At the last 2 photos you see her with her sidekick, Yook Ji Hye.
I must point out that I was hoping for more photos, but Daum is having maintance at the moment, so check RCA daily for part 2 and the G★Star 2011 coverage
