This... I didn't think about it...
It's almost like the heroine committed suicide due to the emotional trauma of the hero. She didn't die but lost her memory. She turned herself into an assassin to kill the emperor, but the emperor opened the door for her. So the heroine felt that this dog emperor had insulted her profession, so she pinned the emperor to the ground and hammered him while he was quietly attending court in the main hall.
So there was a shock: the cold-blooded and overbearing emperor was actually pinned to the ground and hammered by an unknown gentle and lovely little fairy female assassin! Is this a loss of morality or a distortion of human nature? !
Intention: Put aside your grudges and work together to create a better tomorrow!
