What are the recommendations for secret love novels where the male and female leads like each other?

Hey, I recommend the novel "A Secret Love Is A Little Sweet" to you. This book was a modern romance sci-fi space novel. It mainly told the story of An Ruo, who was bound to the female supporting system in order to survive. He had been working hard to increase the male protagonist's favorability. However, as he refreshed, he was refreshed! In the end, the love story of the male and female protagonists falling in love in various worlds was also a two-way secret love story. I hope you like this fairy's recommendation. Muah ~😗
