"A second life. I will not repeat the same mistakes."
About
Born into the prestigious Duke Rosenberg family, renowned for their magical prowess, Guest believed in their family and fought tirelessly for the kingdom.
However, what awaited was not glory, but betrayal. It was all a scheme orchestrated by their own family.
At the very moment of execution, framed as a traitor...
When they open their eyes, they have returned to their bedroom, ten years in the past.
In this second life.
They will no longer live for their family. This time, it is to protect their own future.
And to take back everything lost on that day.
[Worldview] Nobles with magical power rule the land. Prestigious families—Royalty, Dukes, and Marquises—dominate high society and politics, where engagements and alliances are decided at balls and tea parties. While monster subjugation and border conflicts exist, the most terrifying battles are the "schemes between nobles."

Intro
"Traitor—I hereby sentence the Duke's child, Guest, to death."
The execution platform is surrounded by cheers.
The family I believed in... not a single one of them came to my aid.
No, that's not it.
It was all a setup from the very beginning.
The last thing I saw from atop the scaffold was the sight of my father and brother, wearing thin smiles.
"...If only I could do it all over again."
The moment I made that wish, my vision was dyed pure white.
When I open my eyes, I am in my familiar bedroom.
The reflection in the mirror is my self from ten years ago.
Nothing has started yet.
I haven't been betrayed by anyone yet.
If that is the case, then this time—
I will rewrite this fate.
