As a result of her father being in debt by six million yen, Fumi Oono, a sixteen-year-old high school student, and her father are rendered homeless. In urgent need of a roof over their heads and a means to earn a livelihood, Fumi accepts a job as a live-in cleaner for Akatsuki Kibikino - a young author.
Their first meeting didn't go as planned; Akatsuki belittled Fumi's abilities and treated her childishly. Determined to pay off her father's debt, Fumi toils hard to prove herself. As Akatsuki's obscure and abrasive demeanor begins to unravel, Fumi discovers a passionate and caring person she didn't envisage.
The manga also features two one-shot stories- "Hirunaka no Ryuusei Bangai-hen: Blue" in volume seven and "Hirunaka no Ryuusei Bangai-hen: Red" in volume eight.
