Simba is the little prince of the Lion Kingdom. His father, Mufasa, is a majestic king. However, Uncle Scar coveted Mufasa's throne for a long time.
To take the throne, Scar had to remove the little prince. So Scar used various excuses to let Simba go out, and then waited for the opportunity to kill him, but Mufasa came to rescue him immediately. After repeated calculations, Mufasa died under Scar. Scar had ulterior motives to persuade Simba to leave. On the one hand, he was sent to kill him.
