Suguru Narumi was a perfectly normal high school student. One day, on the way home, he got into some trouble, but was saved by the very attractive Miwako Eguchi. Miwako is a music teacher from his high school and the person running the orchestra that consists entirely of girls. He fell in love with Miwako and ended up joining the orchestra.
