@Satsumiko I loved your response!, current Chloe worked hard to get where she is now, little by little she recovered her reputation, the duke also felt for her personality since he did not feel that way for the OG.
The Original vs Current, is a dilemma, considering the current Chloe has most, if not all OG Chloe's memories, it can easily be considered as if the OG Chloe awaken, kind of like Katarina in Hametsu, it's a thin line.
The current Duchess is neither the original Chloe or the original Korean office lady, the new, is product of the memory of both of them.
