There is a program described as “Male and Female Practical Education”, it all started with a single classroom and eventually spread to others. This summer break Arita Atsushi was enrolled in this program. He's afraid he won't talk to any of his classmates because he gets nervous talking to others, especially girls. He doesn't know anything about this camp other than it's being held on a remote island, and he's really hoping the experience changes him for the better.
