After being transported into a book, Claire finds herself framed into marrying Sean—the man originally meant for her sister. Adaptable by nature, she channels her energy into securing wealth, knowing money is the true source of power. But on their wedding night, Sean drops a bombshell: he has an incurable disease. What follows is a marriage of convenience between a gold‑digger and a reckless noble, where Claire masterfully transforms the young lord from a playboy into the perfect "henpecked" husband.
