Yamada is a shy second-year high school girl who is a member of the greenery committee. Kase from the class next to hers is a beautiful girl who is the ace of the school's track team. As a result of the morning glories planted by Yamada, the distance between the two people who have never exchanged words shrinks little by little.
Yamada may be shy and rather clumsy, but the flower gardens at her school have always brought her happiness. Suddenly, a different sort of beauty catches her eye—the vivacious track star, Kase-san. Although the two girls don't seem to have much in common, they soon start a romance where each must learn an important lesson in tending their budding relationship. Can the two girls, so different from each other, learn how to make their first love blossom?
