I recommend " The Divorce of the Alluring Princess " to you. The female protagonist of this book is a modern girl who traveled back in time to become a love-struck princess. In order to get a divorce letter, she deliberately disguised herself as ugly to hide her beauty. However, she did not want to be bound to the palace, so she began to commit all kinds of appalling scandals, such as becoming a courtesan in the sea, becoming a bandit in the mountains, and so on. I hope you like my recommendation.
