She was a modern-day assassin, but after a botched mission, she woke up in another era in the body of the legitimate daughter of the Prime Minister's household. To her surprise, the girl had been bullied to death because everyone thought she was stupid. Since she was using the girl's body, she didn't mind taking on the rest of her family's karma, too. Those who had bullied, schemed against, and humiliated her had better not blame her for paying them back one by one! She would show them that no one could bully a foolish girl! But in the middle of her revenge, where had this seemingly highborn prince come from? And why did he want her to be his personal blood bank? My God! Did he really think she was a harmless kitten just because she hadn't bared her claws?
I just started watching it, and it seems alright so far.
