Ayumi, Kei, Koyoi, Rika and Nao are five middle school friends whose hot topic of conversation is, as always, love. Ayumi dreams of having a boy confess to her and can't understand the idea that receiving unwanted confessions can be troublesome. She even believes that she will happily accept any guy who approaches her - that is, until she receives a love letter from Misao, a large, delinquent high school boy whose very presence makes small children cry! Not wanting to date him but too scared to reject him, Ayumi has no idea what to do, especially when Misao, now nicknamed Beast-kun by the girls, begins following her to and from school. To make matters worse, Ayumi then falls for Mamoru, a boy in her class who is Beast-kun's brother! With plenty of experiences in life and love left ahead, will the girls retain their naive beliefs, or is it time to shake off that brother complex and realize that appearances aren't everything?
