"Lady Alicia Furman, daughter of the Marquis! I hereby annul my engagement to you!!"

With pink-blonde hair and pink eyes, my half-brother declared those very words, all while embracing the shoulder of a Baron's daughter clad in a dress that emphasized her bosom.

Those were words she had heard many times before. The one who had been named trembled, quivering as she awaited her moment of condemnation.

"Well said, my foolish little brother! You won't go back on those words now, will you?!"

I stepped forward as if to shield her, and began to act to make this foolish half-brother understand his place.

Ten years ago, I, what she called a "mob princess," became friends with the villainess (to-be), and learned from her about herself and prophetic-like events that might happen in this country.

First, there was the story of my father, who was said to die during an inspection tour. Next, the story of an epidemic spreading throughout the country. And just as she foretold, the world unfolded exactly as she said----

This is the 10-year journey of me, who was called a "mob princess," and the villainess, Alicia Furman.

The same story is also being posted on Kakuyomu, Novel Up Plus, and Tsugikuru.

☆ Please note that the noble ranks and other titles appearing in this story are uniquely set for this narrative.

The currently serialized part is set during childhood, so there are no romantic developments. These are planned to be added as the characters age.
