Four schoolboys find themselves the last virgins left at school. During the summer holidays, a girl they knew as children 11 years ago, moves back to the neighborhood. Despite their childhood attraction to her, they realize she is a mere shadow of the "princess" they all thought they knew. This story of summer - love, friendship, school, family, the hypocrisy of adults, complications of life, experience and failure is set in an everyday shopping district and shows the clumsiness of children who have developed a little later than their peers. It's a bright romantic comedy that both young and old can appreciate.

Makino Tsukushi is the only poor student at Eitoku Gakuen, the school of the ridiculously rich and privileged that is ruled by Flower 4 or F4, a group of four boys who come from extremely powerful families:

Hanazawa Rui, the introverted son of a large company
Nishikado Sojiro, a player who is the heir of a tea ceremony school
Mimasaka Akira, a madam killer with ties to the underground
If a student gets on the F4’s bad side, he/she gets a red notice and is bullied and driven out of school.
Makino hopes to pass her days quietly-- without drawing any attention to herself-- but one day, she stands up to Domyoji in defense of her friend. The next day, Makino gets the dreaded red notice. Even though she is harassed, Makino decides to keep going to school because she is a “tough weed”. She declares war right back on the F4.
