When Male Protagonists Have the Ability to Read Minds

I, Yan Xi, have traveled through time! Dressed as a character in a book called "The Overbearing Prince Falls in Love with Me"! Just when I was overjoyed and angry, thinking that I could show my ambition! But I discovered that I am neither the heroine nor the supporting character, but a secret guard who was adopted by the prince since he was a child! ! In fact, the secret guard is also very good, but the key point is that I, the secret guard, have never been mentioned in the article? When it comes to my scenes, I either get slapped by the heroine, or I try to trip up the heroine, and then get slapped by the prince! In short, my role as the female N number is clearly to enhance the heroine's personality and highlight the heroine's wit, intelligence, understanding, and the courage to love and hate! ! ! ! What should I do? ? ?
