I recommend the book "It's Just You". The female protagonist is plotting against the original female protagonist for the sake of her beloved male protagonist, but the male protagonist doesn't know about it. After the female protagonist split up, the male protagonist got along with the "personality female protagonist" and gradually fell in love with her. In the end, the male protagonist chose the "character female protagonist." This book was a modern romance with a rich background. I hope you like this fairy's recommendation. Muah ~😗
