They later tweeted another humorous picture of just Baro and Sandeul raising the trophy up high in excitement, looking as if they are drinking in the happiness that comes with victory!  Baro is even pumping his fist while Sandeul either looks like he's having a hard time raising the trophy or is holding back some tears of joy.

The show tweeted, "The strong picture of proof for B1A4's 'Champion Song' win on the January 22 installment of 'Show Champion'!  Do you feel the excitement and happiness of Baro and Sandeul???^^"
