The protagonist Hayako Tasuki is an elementary school gym teacher. Always cheerful, big-hearted and open-minded by nature, she comes off as a wonderful woman with no flaws, but she also has goofy, quirky side to her and likes to be silly with kids. She's generally content with her life, but as far as her love life is concerned, Hayako is rather indifferent: she just vaguely hopes to eventually get married someday with someone that she loves. However, after her father is hospitalized, she starts to think seriously about finding a partner for herself and decides to take steps towards getting married.
