Nori is a big fan of high school baseball and Yumeyama High School pitcher Matsushima. Nori learns that her classmate Ritsuko Ikeda is the niece of the inn where the players stop and is helping during the summer vacation, so she decides to work part-time at the inn. However, I was disappointed to find out about Matsushima's playboy, which I didn't know when I was a fan. During such a part-time job, even if I make a mistake in the third Kitaura futon, I slip into it and fall asleep until morning. With that as a trigger, Kitaura often asks for help !? Nori's summer vacation, which is no longer just a fan, what will happen !?
