Was there a plot in which the female lead liked the supporting male character until she finally fell in love with the male lead?

Yes, there's a novel called " After I Transformed into a Book, I Had an E with the Supporting Male Actor " that meets your needs. The female lead was originally deeply in love with the supporting male lead, but after failing to fall in love with the supporting male lead, she finally got together with the male lead. The plot of this novel was light and humorous, and there were many interesting interactions between the male and female leads. It was worth reading. Other than that, I also recommended a few other novels. If you're interested, you can read them. I hope you like my recommendations.😗
