War

Theo Raeken dies in Liam's arms during the war. He is reincarnated to be Asher Adams. A football star.

A few months later:
Liam Dunbar dies via gunshot wound. He is reincarnated as Aidan Griffin. The new kid at Beverly Hills High School.

Suddenly a new kid shows up at Beverly and is the new star for the MMA team. His name is Aidan Griffin. He meets the star receiver of Beverly, Asher Adams.
Asher and Aidan feel like they know each other but can't place their finger on it.
