Znakey's manga / #MURDER COUPLE(2)

The cover makes it look boring. It isn’t!! Actual BAMF cruel FL, which is a relief, because a regular FL would be an awful match for the asshole ML. FL is a bit crazy, they are a murder couple (?

Saw it recommended as #1. From a comment: The main lead is a girl who is the Princess of the Spirits. She knows that she is a spirit and how to use her powers but her memories are gone. It looks like she is slowly remembering them. We know that the Spirits have disappeared and she entered the Palace to search for them. She ended up becoming a concubine in order to find a way to survive since she was beaten and abused as a slave. The Emperor has taken a liking to her and is protecting her but the clan that controls the haram wishes to harm her. So far the Empress Dowager is just observing the girl and is neutral. We also know that the Dowager is against the Emperor and wishes to dethrone him.
