Which fast-acting novels with only one male lead could be recommended to girls?

I recommend "Dressed Quickly: The Male Lead, I Come to Save" and "Dressed Quickly: The Male Lead's Pet". There was only one male lead in both novels. "Quick Dressed: The Male Lead, I Come to Save" was a sci-fi space-time travel novel. It told the story of the female lead joyfully crossing three thousand worlds to complete the mission of saving the male lead. Every male lead had his own characteristics and personality, and it was very interesting. "Quickly Dress Up: The Male Lead's Pet Pet" was also a sci-fi space-time travel novel. The main character was a supporting actress. In each chapter, she would travel to a different small world, while the male lead was the same person with different identities and personalities. I hope you like this fairy's recommendation. Muah ~😗
