From Vices and Devices:

Yaginuma and Kubata are best friends, and it helps that they attend the same university--and in the same year, faculty, and major. They also share a passion for stage productions, except that Kubata can't get over his insecurities about his own writing. Yaginuma has no such doubts about his scripts, and decides to turn one into an actual production, all the while trying to turn their friendship into something more.
