Which ancient romance novels described the plot where the female protagonist mistakenly thought that she was a male, such as "

I recommend "Seeking Concubine Without Face", which is an ancient romance novel about fighting in the palace. The female protagonist was once the daughter of a general. After her entire family was killed, she disguised herself as a man just to find out the truth. After meeting the prince who had returned to court as a hostage, he realized that he was full of weaknesses, but he still had to turn it around and return to the palace to uphold justice for the people around him. The male protagonist had a myriad of personalities, while the ice-cold prince was domineering and ruthless in his pursuit of the female protagonist. I hope you like this fairy's recommendation.
