Director Tominaga Masanori, known for “Pandora’s Box,” adapts Motoya Yukiko’s quirky play “Ranbo to Taiki” into a film that intricately weaves themes of love, hatred, and voyeurism. Hidenori (played by Asano Tadanobu) and Nanase (portrayed by Minami) have shared a home for a decade, maintaining a strained yet non-romantic relationship. Their lives take a turn when a married couple, Takao (Yamada Takayuki) and Azusa (Koike Eiko), move in next door. The situation escalates when Hidenori discovers Nanase’s affair with Takao, leading him to become fixated on spying on Nanase through a peephole and plotting his vengeful retaliation.
