What is the plot?

Chiharu's day is thrown into crisis when Kyoko's private investigator sends an anonymous email to her workplace exposing her affair and demanding money. At the same time, Chiharu gives Takuya a divorce paper that has already been signed, forcing a direct break in the marriage on paper even before the emotional fallout fully lands.

The episode's early tension centers on Chiharu trying to keep control of the situation while the threat from the investigator hangs over her. The email turns her private life into a workplace danger, making the affair impossible to keep hidden in the normal rhythm of her daily life.

As the pressure builds, the story continues to focus on the consequences of Chiharu's choices and the widening split between what she presents publicly and what she has been doing in secret. By the end of the episode, the decisive action is the delivery of the signed divorce paper to Takuya, marking the most concrete change in the relationship shown in the available episode information.

What is the ending?

Chiharu gives Takuya a signed divorce paper, and their marriage appears to be ending. After that, she quits her job and painting class and then goes missing.

In the ending, the final stretch centers on Chiharu's decision to leave her old life behind and Takuya's confrontation with that choice. Chiharu hands Takuya the signed divorce paper, making the separation concrete rather than only implied. From there, she stops showing up at the places that had defined her daily routine, leaving both her work and her painting class. The episode then closes with her disappearance, which leaves her fate unresolved at the end of the story.

Takuya's fate at the end is tied to the divorce: he is left with the signed papers and the reality that Chiharu has walked away. Chiharu's fate is more uncertain, because the episode does not show where she goes after leaving.

I can give a more scene-by-scene expanded ending if you want, but the available source material only confirms these final events.

Is there a post-credit scene?

I couldn't verify any post-credit scene for Perfect Adultery, Season 1, Episode 13 from the available results. The only directly relevant source identifies the episode's plot setup--Chiharu's fourth lover being Rino and an anonymous workplace email about her affair--but does not mention any end-credit or post-credit scene.

If you want, I can still help by checking whether the episode has: - a mid-credits tag, - a full post-credits scene, - or just a standard fade-out after the final scene.

Is this family friendly?

No, Perfect Adultery Season 1, Episode 13 is not family friendly. The available episode description confirms that the story centers on affairs, a private investigator, an anonymous email sent to a workplace, and threats for money, which already places it firmly in adult-drama territory.

Potentially objectionable or upsetting elements for children or sensitive viewers likely include: - Adultery/relationship betrayal as a central theme. - Blackmail or extortion involving threats for money. - Workplace intrusion and public exposure of private sexual/relationship matters. - A generally mature, suspenseful tone focused on family conflict and secrets. - Possible emotional distress, including anxiety, humiliation, and confrontation tied to the affair plot.

If you want, I can also give you a simple age-suitability recommendation like "okay for teens / not for kids," without spoilers.
