If you can provide more specific information, such as the title of the book, the author, the genre, or the general plot, I will recommend it to you more specifically. Now, let me first recommend a novel that fits the nostalgic tone-"I Watch You Grow in Loneliness." This is a modern romance novel about love and marriage. Although the protagonist Yu Chenmo is a lecher, he still remembers the person he once loved deep in his heart. The plot of this novel is touching and the characters are unique. I suggest you give it a try. I hope you like this fairy's recommendation. Muah ~😗
