A young wife, Miharu, is intrigued when she sees a leaflet advertisement recruiting members for the volleyball club. I watched the practice and liked it, so I decided to participate in earnest from next week. As practice begins, Miharu is pushed hard by captain Natsumi. Natsumi often shows a dubious smile to the courageous Miharu who desperately tries to keep up with the tough practice. As they continued practicing, the relationship between the two progressed steadily, and they became very good senior-junior relations. One day, Miharu invites Natsumi to his house.
