Historical

She is the secret service’s trump card, a  poison specialist, but also a young and cute girl with a sinister  temperament. Contrary to her sweet and innocent appearance, she can  complete any tasks without the slightest hesitation. One day because of  an incomplete black magic, she was sent into the body of a girl who was  deemed as a waste of resources. What kind of change will she bring to  this continent?
    A certain bitter and hateful Prince says, “I believed she was weak  and easy to bully, therefore I broke off my engagement. Only, I didn’t  expect she is a poisonous shrewd. I made an error of judgment.”
    A certain Crown Prince deeply sighs, “She is such a sexy evildoer!  Obviously, she has a frail and tender body, but I wasn’t able to  overtake her…”
    Finally, a certain Ancestor hit the nail on the head, “She is just a bit two-faced!”
    She answered, “You’re just a big pervert!”
    A certain Ancestor carried her into a room. “Then, you are meant for me! A two-faced and a pervert, that’s a perfect match!”
