I've Become a Genius Actor - Chapter 47:

After getting betrayed and killed by the only person she’d loved, Miss Shang wakes up in the body of the cowardly crown prince Shang Wuxin, who, due to her own circumstances, was actually a girl cross-dressing as a boy. After inheriting the crown prince’s memories, Shang Wuxin has three things on her agenda:

1. Clean up the house

2. Gather loyal followers and soldiers

3. Get the throne

From a stumbling lion cub to a majestic lion king, he imagines that his life as a lion would peak and end with him owning a vast territory, dominating the grasslands, terrifying all his enemies while having many wives and concubines.

This is a story of a little man who walks forward silently, in awe, and strives to chase his dream.
