Sex. Something that is part of human nature. Everyone does it and strives to have their happily ever after… Right? In a society where intimacy and romance are constantly everywhere, someone breaks from the mould after years of self-discovery. They send a letter to their past self full of their experiences and lessons learned, in the form of a short documentary. A-Okay brings attention to the hyper-sexualized and romanticized society we live in and how it’s expectations, stigmas, and stereotypes can be harmful to individuals on the aromantic and asexual spectrums.
About two people who are aromantic and asexual and begin living together. Sakiko finds it difficult to live in a society which operates under the assumption that people will fall in love with each other. She meets supermarket employee Takahashi when she goes to support a "fall-in-love" campaign by her junior at work. She is startled when she hears him say that there are people who don't fall in love. As Sakiko's mother keeps hurrying her to get married, she decides to move out and rent an apartment with her friend but her friend backs out at the last minute after reconciling with her ex-boyfriend. Just when Sakiko is about to give up, she ends up living with Takahashi under one roof because of their similar values towards romance.
Best friends Mieko and Makio meet a university student, Eiji, who ends up falling for Makio. Despite everyone being against the relationship, Mieko decides to watch over them as they grow, and their bonds and relationships gradually change.
