I'm prerty sure that the Female Lead was a female originally who had to act like a man when she was a hero.

For some characters in the story, it seems to be a secret too. We don't know why the prince and princess didn't like the original Raul (potential power sturggle?) but I have a feeling the former had no idea. I am up in the air if the princess knew.
Think about it: Raul gained attention as a knight, when she was actively displaying more masculine traits. Before then, she may only have been known as a child with a high amount of power of the goddess. People can forget certain details if given a strong visual cue they maybe wrong. And as a captain, she may have had her own quarters while on missions so the other knights might not know. I can only say the nuns and the prime minister (her godfather) are the only ones who know 100% she is female.
As readers, we all should know 100% as well. I was interested in this *because* she obviously fooled quite a few people, even if slightly unintentionally.
He ran! He ran with just his boxers!
That's what I thought too
