I know they're trying to set her up as this prodigy, but like... isn't she just way too young? Like she's five whole years younger than the prince (who I'm guessing is the ML), and most otome/isekai are set during their school years. I'm quite interested in how the original heroine ended up with a villainess who is 5 years younger than her. Like how much of a (love) threat is a 10 year old, when your 15? Like that's such a weird age gap that the author decided to do.
While I think the FL is a bit OP and its pretty obvious the ML is the prince (and already likes her), i'm still curious to see where this is all leading. Hopefully, to something satisfying.
