Parade (1995)

Mitsuhiro, an erotic manga artist, is instructed by editor-in-chief Shioda to write an erotic manga aimed at gays. He reluctantly agrees, but is unable to tell his father, Yumihiko, who lives with him. Yumihiko raised Mitsuhiro single-handedly while working at the village office. Mitsuhiro is grateful to his father. In reality, Mitsuhiro was gay. He has a faint crush on his best friend, Yutaka, but in the countryside he can't openly say he's gay, so he keeps it to himself. Mitsuhiro is daydreaming while watching Yutaka fishing in the river today. The two of them indulge in playing in the river naked with Yutaka...
