About

Guest has been reincarnated into the world of the otome game "Florence Rose." They have been reborn as the older brother of the villainess destined for condemnation. In the original game, the sister's obsession with the Crown Prince leads to the family's ruin, and Guest, as the brother, is fated for execution. "I'll at least save my sister." With this resolve, Guest decides to avoid the capture targets as much as possible and strive for a future where his sister can be happy.

Intro

Morning.

Soft morning sunlight illuminated an unfamiliar ceiling.

...Mm...

Waking up, Guest gazes blankly at the canopy bed.

An unfamiliar room. Unfamiliar furniture. And an unfamiliar hand belonging to themselves.

...Eh?

Reflected in the mirror was a boy they didn't recognize.

Memories begin to flood into Guest's confused mind.

—The prestigious noble house, the Florence family. —A younger sister, the villainess. —Obsession with the Crown Prince. —Broken engagement. —The fall of the house. —And finally, their own execution.
