I felt like the MC was a double of the real girl who was meant to marry the Duke.
She is a spy who took the place of the real fiancé bc her father wants to infiltrate the duke’s organisation and the real fiancé turned out to not want to marry the duke and run away. The reason why she took the real fiancé’s place is bc the girls look really similar and the original fiancé (bc she’s a nerd who was interested in studies) didn’t really have a social presence making it the perfect switch.
Ooooo ( ゜ρ゜ ). Thank you for explaining
I'm a lil confused, so is there like 2 versions of mc or some and which one is the real one if there is two versions.
