Evelyn Harper's family was plunged into a massive financial crisis, with their company teetering on the brink of bankruptcy. To save the family, her parents forced her to marry Henry Westwood—the supposedly disabled heir of the Westwood family—in place of her sister, in exchange for a substantial dowry. On her wedding night, Evelyn was roughly escorted upstairs by the cold and indifferent housekeeper. The second floor had two rooms; she entered one of them, surrendering to her fate with a heart full of despair. However, the next morning, when she awoke, the man beside her was not the wheelchair-bound Henry! She realized with a shock that she had entered the wrong room and spent the night with the wrong man!
