She Mocked Me, Unaware I’m a Mafia Don

Arthur, the supreme Godfather of twelve mafia families, hides his true identity as a humble nobody engaged to wealthy heiress Isabella. At his adoptive mother's memorial, Isabella lets her lover Julian vandalize the church, destroy the portrait, and publicly break the engagement, trampling his dignity. Despised as ungrateful and arrogant, Arthur endures in silence—until his tenderness is fully crushed. He then unveils his power, punishing all who wronged him.
