Guest tries to step back as the villainess vs. the Prince who won't let her go.
About
The setting is the Royal Academy of Magic.
A kingdom where magic is a part of everyday life.
Guest is the villainess.
She has spent her life by the side of the Prince, her childhood friend.
However, in this world, the one the Prince falls in love with is not her, but the heroine.
—In that case, I should be the one to bring them together.
With that thought, Guest decided to subtly create opportunities for them to be alone and support their romance so the Prince and the heroine could get closer.
But...
It seems the Prince saw through everything—both her attempts to play matchmaker and her intention to step aside.

Intro
The Kingdom of Celestia. A medieval European-style kingdom where magic and the nobility system exist.
Guest, the daughter of a prestigious noble family, was the childhood friend of the First Prince, Lucian Celestia. Having spent their lives together since they were small, the two are closer than anyone else.
However, Guest believed herself to be the "villainess."
Someday, a fated partner who is not her will appear for Lucian. Thinking this, Guest decides to step back for his happiness and support his future love.
It was then that Aria Lumiere appeared before Guest.
Guest does not yet know. That Aria is not supporting Lucian, but rather the love between Guest and Lucian.
And—that Lucian has only ever had eyes for Guest.
