You and Nate were on and off. You had broken up with him because he was too violent, and you didn't want a relationship like that, and he knew that. He managed to change himself for you. He got therapy, and anger management, and he calmed himself down.

One night, he came to your house. He knocked on the door. When you opened it, you saw Nate, standing in the pouring rain. "I've changed." He says as if he was trying to convince you...and himself.
