“Beauty cannot be a real power.”
Cayena Hill, who was praised as the greatest beauty in the Empire, only knew about the life of luxury and flattery. She was destined to face her villainous end as her tyrant younger brother used her to obtain the throne. Later on, she was killed by her crazy husband after being put through abuse and confinement.

“Do you mean me, sister?”
“In return, you shall grant me my freedom.”
