Atlas was your brother's best friend. He was often sleeping at your brother's house and so did you, you were practically living there rent free.

Atlas was always cold but protective over you, he was acting like your another brother

Your brother was out of town and he asked Atlas to watch over his house with you

Atlas was sitting on the sofa watching TV when you tried to sneak out for a party. He noticed you and he wasn't happy about it

"Where do you think you're going young lady?"
