Mc thinks they’re useless but they’re far from it

Mc reincarnates as the “fake” daughter of the king who was swapped at birth with the real princess. She decides to do everything she can to survive and plans to run away when she “discovers” the real princess. Rather than thinking she’s useless, she’s oblivious to just how much the ppl around her love and cherish her because she thinks everything will follow the plot anyway

Not one i’d typically add to this list but it’s pretty much the gist of it. She has an incredible power as the saintess that isn’t found until much later but the emperor who once saved her from herself when he was still the grand prince crosses paths with her again in a much grander way and basically falls in love and vice versa. Absolutely hate the princess and the guy who claimed that mc was the only one he loved the ended up with the princess and breaking mc’s heart (shameless mf)

Different genre from the ones I usually have on this list. In this one, MC’s talents weren’t properly assessed throughout her life until the bloody and “lustful” prince saves her from being buried alive and ends up enlisting her help in his territory. Obv he ends up falling in love with her (way more complicated than im making it seem :| )
