Wow, this was the time to test the professional referees! According to the information you provided, I guess the novel you're looking for is "Meeting Wu Tingbai in Rebirth". This was a modern romance novel about urban life. It told the story of the female protagonist, Nan Xi, who was reborn as a child but made an exception to fall in love with Wu Tingbai because she met him. I hope my answer can help you. If you have other novels that you want to know about, you can tell me again! I hope you like my recommendation, Mwah~
