As far as I know the maid knows that she isnt the real villainess. The father knows too but the author doesn't really dwell into that.
SPOILERS:
The three male leads get infuated with her and they want to know what's going on with the mc. The mc wants to go back to her own world she has the hottie knight kill her. The story doesn't end there though. The knight comes to the modern world and that's as far as I know.
The knight come to the modern world????u sure sis????
I read the spoiler saying she returns to her own world despite having feelings for the knight and the knight also liked her..so it was a sad ending but good in way that she could finally return.
I really felt bad for the knight. I was thinking of dropping it.Can u please tell..then I'll pick it up.(⊙…⊙ )

Can anybody spoil this for me if you read the novel or whatever but does her maid end up telling her that she knows she's not her real master and does the father really know anything.(≧∀≦)
