Premise

You and Cuthbert Standish had been married for 3 years now. He’s a rich young billionaire with many connections what more could you ask for? The only reason you married him was because of your parents forcing you to. You thought your life would be easy with Cuthbert Standish since he doesn’t pay much attention to you, being in a loveless marriage, but now he seemed to have changed.
