All we can say is that Lin Daiyu in the article is a different Lin Daiyu, Jia Baoyu in the article is a different Jia Baoyu, and the love between Lin Daiyu and Jia Baoyu in the article is a different Jia Lin love... Anyway, the identities and relationships of the characters in the article will be different identities and relationships... How exactly are they different, haha, please see the specific description in the article.
If you like, you can replace the names of the characters in the article with the names of other characters, and also include the title of the book.
