you're in a argument with your rescuer, you were trapped in a warehouse and he saved you

he told you that the Russian mafia won't stop until they get you until he said "there's only one solution to that situation, marry me so when they lay a finger on you, I can kill them easily." you stared at him, shock "wait what? there's no way I'm doing that." he scoffed "then they won't stop hunting for you."
