Living in a grand mansion are Takaomi Kamikiza, a fifteen-year-old boy, his adorable seven-year-old sister, Ami, carefree twenty-nine-year-old brother, Hirofumi, and nineteen-year-old butler, Akira. One day, Takaomi arrives home to an unexpected sight of his classmate, Sara Kimishima, dressed in a maid uniform. It turns out that Hirofumi hired her to not only perform housework but to also fulfill his fascination with maids. Although initially flustered by Sara's arrival, Takaomi and Sara's relationship strengthens as they become entwined in each other's lives beyond just being classmates.
