Hey, I know a lot of cosmic science fiction novels contain love plots! I recommend the following books to you: - <Cosmic Matchmaking Network>: It tells the story of an Earth woman and an alien man's blind date. It's a little funny and romantic! - "Humans Are Viruses": This novel involves the interactions between many different creatures and humans, and there are also some sci-fi romance plots! - "Holding Stars for You": This is a fast-paced novel with some cosmic settings and love stories. - Legend of Milky Way Empress: There are many elements of the universe and love plots in this book! I hope you like my recommendations. Muah ~ If you want more recommendations, feel free to tell me!
