This programme is the story of two adolescent girls who arrive at the age of puberty. Yonji, a 6th grader is physically mature compared to the girls of the same age. Her friend, Dana, a 5th grader is very unhappy with her small body. They become friends in a summer school class on traditional dancing, and they discover that regardless of their differences of appearance, there are many things they have in common, including their dissatisfaction with their mothers, who always interfere in their private lives.
