Miwa Nakahara is a Geography teacher at a high school in Tokyo. She’s young, only 25 years old, but unlike her circle of friends, she’s the only one who isn’t married. She’s completely single, with no experience in relationships, and, to top it off, she still lives with her parents.

Despite her beauty, Miwa has a habit of unintentionally scaring off potential admirers. At first, she thought it was because of her nerdy appearance, but over time, she realized it was just something about her.
