At first Marcia is supposed to be in her early twenties (as it was mentioned that she's past her marriageable age) then it said she was a "foolish teenager" pre-soul exchange.
Then the duke is said to be older than her however they mentioned he is 6 years older than Larissa who is 13? So HE should be 19.
WHICH ONE IS IT??! (╯°Д °)╯╧╧
