Kusuriya no Hitorigoto Gaiden: Xiaolan Kaisouroku

Though born into poverty, Xiaolan was content with her simple life caring for her siblings. But out of desperation, her family was forced to make a terrible decision... Sent to the imperial palace as a servant, Xiaolan now spends her days washing laundry and tending to the consorts' needs. She doesn't mind her new lot in life—after all, there's food!—and soon makes friends with another servant, a strange girl named Maomao. Can the two help each other as they find their way in the scheming, status-seeking society of the rear palace? (Source: Square Enix)
