Description
Akiho Kōsaka is a second-year high school student who serves as the class representative. She is widely regarded as a model student, recognized for her academic excellence, athletic ability, and an attractive, aloof appearance that makes her a popular figure in her school. Physically, she has chin-length grey hair with distinctive black tips and grey eyes.

At the start of her romantic relationship with her boyfriend, Haruka Shinozaki, Akiho is revealed to have absolutely no prior experience with intimate relationships. To compensate for her inexperience, she tends to over-analyze romantic and sexual topics, approaching them in a straightforward and academic manner as if studying for a test. This habit is a trait she inherited from her mother, Fuyumi Kōsaka, who ingrained in her the practice of casually discussing sexual subjects from a young age. She typically speaks in a very direct, deadpan, or monotone voice, which adds to the contrast when she discusses explicit content.

Akiho’s primary motivation is her desire to be a good partner to Haruka, whom she genuinely cares for. She devotes herself to studying what she believes a girlfriend should do, sometimes jumping to the conclusion that a situation requires something sexual. This dedication stems from a serious and perfectionist personality; she applies the same diligent, earnest approach to her relationship that she does to her schoolwork. Her goal is to make Haruka happy and to ensure she is not abandoned, leading her to research various romantic scenarios.

In the story, Akiho is the main female protagonist and her evolving relationship with Haruka is the central focus. Much of the narrative revolves around the comedic misunderstandings that arise from her naive over-analysis of romance versus Haruka’s desire to take things slowly. Her role is to drive the plot through her well-intentioned but often misguided attempts at intimacy, which contrasts with her otherwise perfect public image.

Key relationships define her social world. Her bond with her boyfriend, Haruka Shinozaki, is the most significant, as she learns about love and social interaction through him. Her mother, Fuyumi Kōsaka, is a crucial influence, as she is the source of Akiho’s bluntness regarding sexual matters. She also interacts with Shizuku Ariyama, a childhood friend of Haruka whose teasing often leads Akiho to form incorrect assumptions about her boyfriend’s preferences. Additionally, she views Seiya Hoshikawa as a rival due to his close friendship with Haruka.

Throughout the series, Akiho shows subtle development. Despite her popularity, her blunt and strange behavior initially keeps classmates at a distance, but through her relationship with Haruka, she slowly begins to open up and improve her social interactions. She gradually learns that a relationship does not have to be "extreme" and that it is acceptable to progress at a slower, more comfortable pace.

In terms of abilities, Akiho excels academically and is a skilled athlete, which contributes to her status as the school's "madonna". However, she has a notable deficiency: her cooking is exceptionally poor. Her attempts at preparing food often result in inedible or even dangerous dishes that can make others ill.
