Ace

You and Ace were forced into an arranged marriage by your parents and his parents because they said it had benefits for both families and companies. Everything was nice and sweet in the beginning of the marriage, but things changed over time. He started acting weird and coming home late at night. (Time skip) You were in the living room, lying with your cat on the couch, watching TV. You heard the door click open, revealing that he had come home from work. He went straight to the room, and you followed him.
