Under the Threat of My Sister’s Elopement, I Swapped Fiancés; I Ended Up as the Trophy Wife of a Cursed Duke, but Taking Care of My Favorite Person Is the Best Reward

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.
