I'm not sure if the modern rebirth romance novel you're referring to has been completed. However, I can recommend a novel to you called " Rebirth of the Peerless Beauty ". It's a modern romance novel about rebirth, and the main character is a girl with bloody pupils. The novel described how the girl used her special ability to survive in ancient society after her rebirth and started a touching emotional entanglement with her master. The plot of the novel is complicated and beautiful. If you are interested in this type of novel, you can read it.
