Moe (Junko Mihara) is a teenager who has left her family's country home to share an apartment in Tokyo with her older brother Jun (Eiji Okada), in order to get a good high-school education in the city. She does the housework for her brother, who is a successful photographer with a romantic interest in his attractive assistant. Moe and her brother share the same bed -- out of practicality -- but that situation changes when Moe awakens sexually. Her brother's interest is strictly in his assistant and he has no clue that Moe is in a quandary about her own sexual leanings, even when she tries to ruin his relationship with the photography assistant. Moe then looks for other ways to express her desires, and she starts to develop a relationship that -- as unlikely as it may be -- will at least solve her dilemma.
