A full-length fantasy romance manhwa/webnovel story in the exact style and tone of the Korean webtoon "A Wicked Husband" (악인 남편) / Manta adaptation — dark romantic tension, gorgeous atmospheric art descriptions, slow-burn yandere male lead, possessive obsession, political intrigue, and steamy emotional chemistry. Use beautiful, detailed prose with manhwa panel-like scene descriptions (intense eye contact, lingering touches, dramatic shadows, candlelit chambers, battlefield flashbacks, trembling hands, flushed cheeks, etc.).
