A Story Written with Water

Shizuo notices that Yumiko's face strongly resembles his mother Shizuka. Given his mother's affair with Denzo Hashimoto, Shizuo fears that Yumiko could be the biological daughter of Shizuka and Denzo, making her his half-sister. When he directly asks Denzo about this possibility, Denzo hesitates before denying it, which only deepens Shizuo's suspicion without providing clarity.

The resemblance between Yumiko and Shizuka is first noted when they meet as potential marriage partners, establishing the unease that follows.

Shizuo is overwhelmed by emotional turmoil, his obsessive attraction to his mother, the fear that he may have married his sister, and his inability to act on his true feelings. In a moment of despair, he asks Shizuka to join him in double suicide as a way to escape his psychological pain. Shizuka is confused and cannot understand his motives, revealing the depth of his hopelessness.

Shizuo's unhealthy attachment to his mother and his troubled mental state are established early in the film, foreshadowing this desperate proposal.

Shizuo keeps his suspicion about Yumiko being his half-sister hidden from her. This secret, combined with his unresolved feelings for his mother and guilt about the marriage, manifests as emotional distance and coldness. Yumiko senses this and feels unattractive and unvalued, not knowing the true reason behind his behavior.

Shizuo's inability to confront his mother about Yumiko's parentage sets the stage for his withdrawn behavior in the marriage.

After months of emotional strain and distance, Shizuo and Yumiko finally become intimate. This sexual connection appears to break through his psychological barriers, allowing him to see Yumiko as a person rather than a possible sister or a replacement for his mother. For the first time, he feels genuine affection for her.

The growing tension between them throughout the marriage hints at the possibility of genuine connection developing.

Shizuo is portrayed as a shy, introverted salaryman who has not established an independent life. His father Takao is frequently hospitalized and unable to support the family, leaving Shizuo as the primary male presence in the household. His emotional dependence on his mother appears to be both psychological and perhaps a factor in his reluctance to leave.

The opening scenes establish this living arrangement and hint at the unhealthy dynamic between mother and son.

The movie never definitively confirms or denies whether Yumiko is Shizuka's daughter. When Shizuo confronts Denzo, he hesitates before denying the possibility, leaving the question unresolved. This ambiguity is central to the film's tension and remains one of its central mysteries.

Denzo's hesitation and vague denial plant the seed of doubt that haunts Shizuo throughout the film.

Denzo Hashimoto is a wealthy, confident man who has an affair with Shizuka while her husband Takao is hospitalized. He uses his wealth and influence to manipulate family relationships, ultimately proposing the marriage between his daughter Yumiko and Shizuo. His presence represents power, control, and the source of Shizuo's deepest anxieties about incest.

Denzo's affair and influence are established early, setting up his later role in arranging the marriage.

The film ends with Shizuo finally feeling love for Yumiko after months of coldness and secrecy. However, the underlying mysteries, Yumiko's possible parentage and Shizuo's earlier suicide proposal, remain unresolved. This creates a bittersweet tone: hope for their relationship exists, but the dark secrets and past trauma continue to shadow their future.

The unresolved questions about family relationships and the earlier emotional crisis set up the uncertain ending.
