Transmigration Inside the Novel: Prince Turns out to Be the Princess

Once she dressed up as a man: the notorious prince of the dynasty, deceiving everyone; 
Above all, she fooled the world but was tripped up by one person. 
At first, he looked at her with disgust and said, "I didn't expect you to be gay." 
She glared back in anger and said, "With your looks, even gay men wouldn't like you!" 
Later on, he wrapped his arms around her and cockily raised his eyebrows, "Is it forbidden for me to hold my own man?" 
She clutched her blanket, covered in ashes, and replied, "I'm not into men!"
