The second story is about a pro archer who's embarrassed about her masculine body, and her classmate unexpectedly finds out about her embarrassment...
A perverted spice teacher takes the stage in the third story. She likes her students, but not the male ones, who are too unrefined for her.
The fourth story is about a female painter and her subject. She quit painting in front of other people for a while, to protect herself.
Both stories are ecchi, and the one chapter format doesn't give the author much of a chance to show the characters interacting. The second and fourth stories are more artistic than the others, because they focus on more realistic problems. The art is simple and a little rough, but this gives each story a feeling of spontaneity and genuineness. The series seems to be titled Concerto after the first story, seeing as the rest of them don't have anything to do with music.
