I recommend the sci-fi space-time travel novel," The Golden Movie Queen of Reverse Penetration." The female lead traveled to the modern world and became an assassin. Her identity was mysterious. Although she was not a princess, she was still a prestigious movie queen. The male lead was the CEO of the Xiao Corporation. He realized that the female lead's identity was not simple, and the love story between the two was also very exciting and vivid. I hope you like my recommendation.
