Images of an emotional B2ST after their 'Music Bank' win

Last night on KBS' "Music Bank", the boys of B2ST delivered a crisp performance of their comeback track "Soom", drawing fangirl screams that could have probably been heard all the way to Japan. It was an especially memorable night for B2st, however, as they took home their very first 'K-chart' victory. Stunned to learn that they defeated the triple-crown champions, 2NE1, the boys were almost speechless and could only repeat, "Thank you, thank you very much" as the show scrolled through its end credits. Photos of the boys' emotional reactions backstage have just been revealed, giving their fans an intimate look at how relief and triumph can only be expressed through tears.
