Ichikawa Etsuko used to be a regular high school girl and lived a poor but normal life, but her no good dad accumulated so many loans that he sold her in order to get rid of his debt. Typically, this story wouldn’t end well with the girl being sold into prostitution, but, luckily for Etsuko, she's forced to become a maid to a rich family. Her job is to attend to the every need of the Kurofuji siblings, the brother Arei and the little sister Erika who are French and Japanese. Etsuko seems to never get anything right, but she better or the alternative won't be pretty.
