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! The shoot started from inside a moving car so that the participants could relax their bodies and minds 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.
