The Day I Left, He Lost Everything

I was holding my wedding invitation to see my best friend Nora. But I saw the intimate video of her and my fiancé on TV. I had spent ten years helping my fiancé rise to the position of a mafia don. I gave him everything I had, only for him to cheat on me with my best friend. Because I couldn’t have children, he forced me to give up our wedding and even suggested I stay behind as a nanny for their baby. But now that I’ve finally let go of everything and walked away… why is he the one who regrets it?
