Natsumi Kawashima is a young fifth-grader who longs to grow up and become a woman. While crushing on an older hair stylist, Natsumi is embarrassed because of her age. Natsumi runs away and steals some nuts from a lady handing them out to women only in the mall. When Natsumi is eating the nuts, she notices that some of them are pink. The next morning, Natsumi wakes up with the body of a beautiful young woman. She does not notice her body transformation until her older crush, Toji Yashiki, asks her about being a hair model. They go on a fabulous date after Yashiki gives her a makeover.
