駆け落ち予定という妹の脅しで、婚約者を交換しました。代わりに呪われ公爵さまのお飾りの妻になりましたが、推しのお世話係は完全にご褒美です

Just before her wedding, Joan is blackmailed by her sister, who plans to elope with Joan’s fiancé. As a result, Joan ends up marrying her sister’s intended fiancé, a cursed duke who hides his face behind a mask. However, Joan has admired the duke from afar for a long time. Though the duke keeps his distance from people and Joan is little more than a decorative wife, she is undeterred and enthusiastically takes on the role of caring for him. As she grows closer to Larry, the duke’s steward, her feelings deepen. But things take a turn when her sister, overwhelmed by the pressure of heir training, storms the duke’s mansion in an attempt to drag Joan back as a servant…

This is a love story between a fiercely positive heroine, who devotes herself entirely to her beloved’s happiness, and a hero who finds unexpected comfort in the weight of her love.

A happy ending awaits.
