Four separate stories explore relationships between childhood friends and unexpected romantic developments. In the first, a reserved high school girl forms a bond with a childhood friend who is six years her senior. The second follows a top archery club member and his close friend, who gradually realize their feelings for each other. In the third, a dependable senior receives a confession from a younger childhood friend with a devoted personality. The final story centers on a high school girl whose childhood crush unexpectedly becomes her new assistant teacher.
