The Anime Lad
Sajou earned perfect scores on his entrance exams but needs help preparing for a chorus festival. Kusakabe, a guitarist who performs with a band, offers to practice with him after school. Repeated rehearsals turn an unlikely conversation into growing affection. Academic achievement has not supplied a useful procedure for this development.
Gigguku
One boy approaches music with careful effort. The other already lives through guitar and performance. Chorus practice gives Sajou and Kusakabe a reason to keep meeting after school, and every shared song brings their different personalities closer. The romance grows from something wonderfully ordinary: one classmate deciding to help another!
Father's Basement
There is very little narrative machinery here, so anyone expecting constant melodrama may find the film slight. That simplicity is also its discipline. Chorus practice gives Sajou and Kusakabe a believable reason to share time, while their different temperaments supply enough uncertainty without piling on artificial obstacles.
