Ever since their debut, BEAST has been performing their title-song Bad Girl from their first mini-album Beast Is The B2ST. Well, it looks like they are now going to change things up as they will be performing their follow-up track, Mystery, on this week's Inkigayo! I am expecting a new atmosphere from BEAST as Mystery has quite a different feel. Will they rock the stage well with Mystery? Stay tuned to allkpop this Sunday to find out!
