Yuko Shiraki and Mizuki Yayoi transcend the boundaries of senior and junior actresses, and are reliable like 'beautiful sisters' even though they are co-starring for the first time! We started shooting from inside a moving car so that the participants could relax both physically and mentally in the great outdoors, away from the studio! The two of them gave each other jelly snacks and yucked and woofed. From the service area, I thought they were divided into separate cars.
