"Lady Amaryllis, I want you to marry me." An unbelievable proposal from the Crown Prince, a man rumored to be cold-hearted and a hater of women! However, this is supposed to be nothing more than a proposal for a contract marriage... or so she thought. Despite the arrangement, the Prince’s surprisingly gentle behavior makes her feel like she might be misinterpreting his true feelings. Amaryllis, the daughter of a Viscount, possesses an extraordinary talent for estate management. It was this very talent that led her to be chosen as the fiancée of Thomas, the next Earl. However, Thomas treated her like a tool—shamelessly dumping all the strategic planning and management onto her while claiming all the credit for himself. To make matters worse, Thomas begins an affair with a Duke’s daughter. When Amaryllis confronts him about his infidelity, he causes a public scene, shouting, "Our engagement is annulled!" Just as she finds herself wishing she could simply vanish from the spot, the Crown Prince—who happened to be in the area for a secret inspection—appears before her and proposes on the spot...?!
