How Can I Save My Life by Dressing up as a Prince Disguised as a Man?

Yu Yiren never thought that she would just take a nap and then be transported into the book and become the cannon fodder prince in the book, the kind where a woman disguises herself as a man. In order to save his life, Yu Yiren decided to start with the most difficult to deal with, the regent. So the arrogant, domineering and cynical prince in the past became a little follower who was always attentive to the regent. Yu Yiren: Does the regent still need bodyguards? The servant is ready... Are the Regent tired? How about I give you a shoulder squeeze... If the Regent needs anything, just ask me, and I will do my best to complete it... After much effort, Yu Yiren finally conquered the Prince Regent, but she didn't expect that the waistcoat disguised as a man would also fall off. Just when she was about to run away, the regent turned around and pushed her against the wall, "Run away after flirting? Choose one, does the prince want to marry me or let me enter the palace?"
