Please recommend a novel where the male protagonist likes another person and the female protagonist does not interfere with their relationship.

I recommend 'Wear the Female Lead Quickly, She Doesn't Want a He Ending' to you. The female protagonist of this book was a transmigrator. Her mission was to become the girlfriend of the supporting male character from a different plane, but she did not want to become the girlfriend of the male protagonist. In different planes, she would develop feelings with people other than the supporting male character, but the female lead would not interfere with the relationship between the male lead and others. The plot of this novel was light and interesting, but there were also many sweet scenes. I hope you like this fairy's recommendation. Muah ~😗
