I have yo say that description bothers me. The I was a cruel woman by forcing commonet men to be my concubines just sounds bad. Why don't you do the same when the emperors abuse that power against women of all level. Say I was an evil emperor by forcing all woman to become my concubines.
The description is ceingy. I read some chapters and waiting for more. The empress was not cruel but a stupid bimbo for thinking that not a single male concubines, like the female concubines, was planning to kill her. She forced her desire to own guys like any other emperor but the problem is that she was doing it wigh guys that was too obsess with her, and she didn't provide affection. That happened with her slave. Plus, they want power.
I truly wish you would describe the inteo better. This is the story of a bimbo who got the power of the empire but didn't know how yo use it and for that she got to escape her own palace and start from zero.
