haha that reminded me of something on what Darkie told me about xD
She said when DAIGO invited AKIHIDE to join BREAKERZ (as Aki-sama's the last member to join the group) , they want to be a
cool band which will not say any gags during the MC
but unexpectedly in their 1st live performance as BREAKERZ which took place at SHIBUYA-BOXX , during the MC , DAIGO accidentally said a gag & the rest had to refrain from laughing
maybe they had that same expression as that gif you posted ? xD
