Akuyaku Reijou no Nariagari

Lady Eliza, the daughter of a duke, is a young woman whose passion for gemstones often leaves her lost in her own world. Her life takes a dramatic turn during her wedding ceremony with Prince Makis, a man known for his unfaithfulness. As she is about to be crowned, her unparalleled expertise allows her to instantly recognize that the tiara—a revered national treasure—is nothing more than a forgery. Without hesitation, she publicly exposes the counterfeit piece and dismisses it as worthless trash. Her blunt honesty comes at a steep price. Enraged by the humiliation, Prince Makis immediately annuls their engagement on the spot. He goes a step further by banishing Eliza from the country entirely, stripping her of her home and status in a single breath. What was meant to be her coronation as a princess instead becomes the catalyst for her exile. Yet, this harsh punishment proves to be an unexpected blessing. Rather than facing ruin alone, Eliza is warmly received by the crown prince of a neighboring nation. Far from the treacherous court and the adulterous fiancé who discarded her, she begins a brand-new chapter of her life abroad, stepping into an unforeseen future where her unique talents may finally be truly valued.
