Noel Hiiragi feels that her life is already stressful enough, given that she lives alone and works at a call center, when her mother suddenly sends her a six-drawer wardrobe. Hoping to return the furniture after trying to squeeze it into a corner of her tiny apartment, she calls her mother to complain about the unexpected burden, but her mom only vaguely tells Noel that it is "her turn." When Noel returns from a night of drinking, she finds a chubby child in her apartment eating her food. Shocked and confused, she eventually discovers that her mother's wardrobe contains six strange children who claim to serve the current mistress of the Hiiragi family. Refusing to accept this blunt explanation, Noel struggles to adapt to her new lifestyle, wondering whether the children's service is a blessing or a curse.
