I recommend the modern romance novel, Memories of my childhood, to you. The female protagonist is called Meng Xiaoxiao. I'm not sure about her age, but she seems to be a little older than a teenager. After her mother remarried, she met the male protagonist's father, who was a friend of her stepfather's son. The male protagonist liked the female protagonist the moment he saw her, but the female protagonist didn't like him at first. Their relationship went through many twists and turns before they finally got together. I hope you like this book.
