Trivia: In the manga, Utsumi Yukie is described as the class president, hence her reputation of the leader is obvious in the lighthouse scene. Lead character Nanahara Shuya, as the deleted scenes show, is the star basketball athlete, hence his popularity.

Trivia: In the bungalow, two female students, Hirono and Mitsuko, are having a beef. Hirono taunts Mitsuko, who loses patience and cries out, 'I've had it! Why does everyone gang up on me, what did I do!' In a website dedicated to the film, it states background information [most likely from the manga] that Mitsuko is the 'class slut', hence Hirono's accusations of Mitsuko stealing her boyfriend, among others, is justified.
