Although the producers had wished to keep all of the names hidden until shooting, it proved to be impossible with the high speed of the Internet. "Since the rumors are so fast, the names of the main members have already been leaked," said an industry insider. The show will film its first episode on October 26th. The cast members of the second-season 'G7' were picked from currently popular female idol groups, with two slots being reserved for the winners of an audition process. "The big framework of the show won't differ too much from season 1," said a representative for the program. "But we are planning to showcase a new type of farming variety."
