“Do you love...me?” My eyes stung as I asked my so-called husband.“No,” he said quietly. “I don't love you. I don't need to love you. I just need to take care of you as I promised your father before he died.”My world crumbled down on me.His words hit me like a physical blow. I staggered back, the world spinning around me. “S-So that's it? This whole time, you've been with me out of some sense of duty?”Elijah looked away, unable to meet my gaze. “Your father asked me to look after you, to make sure you were happy and safe. That's what I've been trying to do.”“Fine then. Let's get a divorce!” I announced, loud and clear.___Ash always believed he could make his cold and vicious hubby fall in love with him.However, after three years of marriage, Ash received only betrayal from Elijah.
