Hikari, Hibiki, and Mei are the school’s three most popular girls, and they are always together as close friends. The three of them all fall for a male student teacher at first sight. After secretly becoming intimate in the empty library, they end up competing for his affection in the infirmary and the classroom. Under the pretense of a summer training camp, they arrange for a car and then spend their time at a traditional inn, where they can’t help but passionately seek each other out.
