It means that she was originally a cis woman, even as a holy knight. Her being a man was a lie spread so she wouldn't be pressured to marry and settle down, as woman are. She was basically undercover, although some knights seem to have known, and some of them still joke about her being a man because of how unladylike her lifestyle made her. I think this was explained in the first few chapters?

I don't think it was common knowledge, all her admirer-ladies definitely didn't seem to be aware, but I didn't think she kept all her knights in the dark either. They can't have a woman changing in the same room as men no matter how masculine she looks and acts, so the other knights had to have been made aware. But I was definitely left with the impression that not only is it not widely known that Roel was a woman, but also she and the church encouraged the misconception.
Even just logically, there's no other way that someone like Roel, who keeps reminding her knights she's a woman every time they tease her, and is such a sincere person in general, would have let a rumour like that spread unless it was for a purpose.
Okay but Roel has mentioned a few times now that he originally was a woman! I really want to know what he means by that and the story.(๑•ㅂ•)و✧
I love them and even if it might be a cheap way of making it a hetero pairing i dont care anyone. The characters make the message of loving someone despite such silly things very apparent (=・ω・=)
