A 14-year-old millionaire Yoshitaka received an enormous inheritance as a result of his parents' death in an accident. Later after firing the original maids, he needed to be looked after so he decided to hire new live-in maids. While originally expecting an elderly woman to take the job, two runaway girls, Izumi, 14, and Mitsuki, 13, end up accepting the job as means for a home and income. Another girl, Anna, later becomes a maid as well, and all three live in the mansion with Yoshitaka.
