The Baby Concubine Wants to Live Quietly

I possessed a supporting character in a reverse harem novel. 

As a young concubine who gained the interest of the emperor. The concubines, the male lords, eventually killed her for treason. 

Fortunately, I possessed her just as she was entering the Imperial Palace. Everyone in the Imperial Palace was wary of me, but didn't hate me yet. I don't need, nor do I want to be loved by the emperor. 

"Come to my room tonight. I'll read you a fairy tale!"
'Woo, don't cry. I'll give you this."

But why is everyone so soft towards me? I couldn't understand.

NOTE: This is a promo manhwa for the novel of the same name.
