Last May 20, the making of Ottogi Ramen CF was released by B2STTV. The CF went on-air earlier last month.
In the plot of the CF, b2uties were crowding the place as they see that B2ST are coming down from the stairs and about to pass by, one b2uty went on screaming to Doojoon to get his attention and forcefully pushed to him a heartshaped-form of ramen cups. Initially, Doojoon got a mad expression but after trying out and tasting the ramen together with the other members, he changed his mood and wouldn't like to stop eating it.
A really hilarious ad. Check out the CF making here:
