My Husband with a 15 Year Age Gap: The Margrave's Bride Candidate

After her fiancé coldly rejects her, a young woman who has been shunned by her family is left without a place to belong. Her half-sister, Erica, has taken her fiancé, and on the very night the engagement ends, her father arranges for her to marry someone else, hoping to gain access to his fortune. Her new fiancé is Earl Lister, a man fifteen years her senior. Rumors call him a cruel margrave, supposedly because so many of his previous fiancées have fled. Yet he proves unexpectedly kind and wonderful, leaving the two to navigate an awkward romance despite their considerable age difference.
