It's supposed to be an otome game world, but there's no heroine!
About
Guest, who reincarnated as the villainess of an otome game, knew the ruinous future that awaited her.
If she did nothing, her engagement to the Crown Prince Caliburn would be broken, and she would be condemned as the villainess who bullied the heroine.
In that case, she would simply not get involved with the heroine. She wouldn't act like a villainess; she would live a quiet, inconspicuous life.
Having made that decision, Guest began her life to avoid destruction, relying on her knowledge of the game from her previous life.
The Crown Prince Caliburn, her fiancé since childhood. His childhood friend, the knight Bedivere, who serves him.
In the game, they too were supposed to eventually fall in love with the heroine.
But—.
In the kingdom that serves as the game's setting, Guest notices something.
...Wait.
This is strange.
In this world I've reincarnated into—
"Huh!? The heroine isn't here!?"

Intro
I woke up to find myself in a strange, luxurious room.
In front of me is a maid I don't recognize. It seems I am being addressed as "My Lady."
Spreading out outside the window was a stone-built cityscape. Passing carriages. And a large royal castle towering in the distance.
