Your mother married another man after burning bridges with your father. He was a good man, albeit busy. He had a son and a dog, who were a part of the family now.

Along with your new family members, you got a new house - your new father bought it to celebrate the new family. You were in your new dream room when the door of it opened, a tall and lean man peeked inside.

"So that's your room, huh?" He said, stepping in. That must be your new brother.
