"The Season of Infidelity," Starring Ren Osugi—Bondage and Emotional Turmoil as Depicted in Kiroku Dan’s Original Work

A sensual drama based on a story by Dan Oniroku that quietly seeps into your heart

Based on a story by Dan Oniroku and directed by Ryuichi Hiroki, *The Season of Infidelity* is a psychological drama that prioritizes a “quiet afterglow” over flashy spectacle.
Ren Osugi stars in the film.
With his unobtrusive performance, he delicately portrays the contours of fluctuating emotions.

The story includes several scenes featuring bondage,
which add depth to the work’s overall understated yet poignant sensuality.
What’s striking is that these depictions aren’t sensational; rather, they gently accompany the story, much like its “breath.”

Spoiler-Free Synopsis—The Moment a Couple’s Relationship Changes

The protagonist is a middle-aged writer who once aspired to write literary fiction but now makes a living writing erotic novels.
While he depicts sex boldly in his stories, his real-life marriage had grown somewhat cold, and a rift was beginning to form between them.

One day, he discovers his wife’s infidelity.
Emotions he couldn’t quite define as either anger or sadness swirled within him,
and the familiar sights of everyday life gradually began to take on a different meaning.

There aren’t any dramatic incidents.
However, through the length of the silences, the shifting of their gazes, and the way their conversations falter—
—these subtle changes gradually reveal how the distance between the couple slowly shifts.

While there are bondage scenes in the work,
they are not so intense as to disrupt the story; rather,
they are treated as “a single depiction” that quietly reflects the characters’ emotions.

Overall Review—A film for adults, where quiet sensuality and emotional turmoil intertwine

"The Season of Infidelity" (
) is not a film intended to provide the kind of stimulation typically found in erotic films.

Rather,
this is a work best appreciated as a psychological drama
that quietly observes how the closest of relationships—that between a husband and wife—gradually drifts apart.

Ren Osugi’s restrained performance naturally conveys the protagonist’s fluctuating emotions.
Furthermore, the sensual scenes—including bondage—deepen the story’s aftertaste without becoming excessive,
lending the work itself a sense of “quiet, mature sensuality.”

After watching it, a gentle sensation lingers deep within your heart.
Feelings that are hard to put into words slowly build up,
It’s a sensual film that truly resonates with the heart.
