Need a name for this AU concept

So:

Simba doesn't want to go back to Pridelands even after Nala tried to reason with him,not that he's scared.. he just doesn't care about anything that isn't "Hakuna Matata",even gets into a fight with her beacuse of their argument about it and completly ignores Mufasa's ghost. Scar stays as the king and Pridelands is ruined.
