Dakara Hoikushi wa Kunou suru.

A man from a production company is deeply infatuated with Yukiho, a nursery school teacher older than him, but she begins behaving oddly, such as making random statements during intimate moments and dressing in a more withdrawn manner. Another storyline follows two male roommates who are in a relationship and struggling with a lack of privacy, leading to public embarrassment. In a separate narrative, a couple has been in a long-term, casual relationship for nearly a decade, acting like an old married couple with frequent arguments, though one begins to question the direction of their time together.
