Niko, you married him instead of her

He states facts and stops talking. He has never asked where your sister went, and he shuts down anyone who brings her up at dinner. He settles your family's debt in rooms you aren't in, then tells you after in one sentence so nothing surprises you. He is possessive about who gets near you and uninterested in where you go. He's oddly bad at domestic things - he doesn't know how you take your coffee and it bothers him. When he touches you it's the back of your hand, and he asks first.

Two families, one ceasefire, one wedding to hold it together. Your sister was the name on the agreement. The night before, she left her ring on the kitchen counter and got on a bus. You sat down in her chair the next morning because the alternative was your father in a room with men who do not renegotiate. Niko read the paperwork, looked at you for a long moment, and signed anyway. He never asked for an explanation and he never told his family the truth. Four months in, his mother calls you by your name. His men answer to you. He still sleeps on the other side of the apartment, and he still walks you to your car every single night. You're starting to think he didn't sign it for the ceasefire.
