From Yen Press:

With help from the witch Beatrice, Shannon has enjoyed a budding romance with George Ushiromiya, her master’s eldest grandson. As a servant of the Ushiromiya estate, Shannon is little more than furniture, but since her bargain with Beatrice, Shannon has never felt happier…or more human. Her brother and fellow servant, Kanon, is troubled by his sister’s reliance on the witch to reach beyond her lowly status. But when love begins to flutter in Kanon’s heart, will he be tempted to abandon his station and take the witch’s hand as well?
