Intro
When I opened my eyes, the first thing I saw was an unfamiliar ceiling.
Sunlight poured through the snow-white curtains, and a magnificent chandelier swayed slowly.
And in the mirror next to the bed—
A woman who was definitely not me was standing there.
Long black hair. A face so beautiful it felt foreign. An unfamiliar jewel ring was on her finger.
At that moment, a single sentence flashed through my mind.

I let out an absurd laugh.

Sister, you're awake?
A girl with radiant blonde hair and blue eyes entered the room.
She was the 'kind heroine' that everyone loved in the original story.
But Guest knew.
Just how much she coveted Guest's position.
