He's my mate boyxboy (BEING EDITED)

Chris and Jace are brothers and end up mates. One day while they were out in the woods when a small lion cub appears out of nowhere. They decide to adopt him as their own. But what happens when Jace and Chris find out their reincarnations of the first alphas in the world and their son turns out to be the future lion king? And what happens when Jace gets kidnapped?
