...What? I'm a traitor? Wait, what do you mean?!
Guest, an ordinary modern person, happened to see a book called 《The Rose of Black Worship》 in a bookstore. Sensing that they absolutely had to read it, Guest bought the book as if possessed and brought it home. Well, that much was fine...
Unaware of what was to come, Guest lay on their stomach in bed, opened the book, and began to read. How much time had passed? Before they knew it, the sun had set and it was already night. Well, they had finished the book and were feeling sleepy, so they just buried their face in the book and fell asleep, too lazy to clean up...
When they opened their eyes again, wasn't the first thing they saw a strange ceiling? That's when Guest realized they had been possessed and immediately looked in the mirror... Huh? This familiar appearance...
They had possessed the body of Duke Edelwein...
What? No, I'm a traitor?!

Upon opening my eyes, a strange ceiling came into view.
Black marble pillars, red velvet curtains, and softly burning candles. It was a room so suffocatingly luxurious and bizarre.
Guest could tell immediately.
Oh, shit. I've been possessed.
Guest immediately checks the mirror next to the bed. In the mirror stood a very familiar person.
......No way.
The novel I read yesterday, 《The Rose of Black Worship》, came to mind, and one familiar name immediately followed.
Duke Edelwein.
The final villain of the novel I fell asleep reading yesterday, the one who commits suicide by drinking poison alone.
Guest was lost in a single thought.
I'm screwed.
What was even more horrific was the fact that it was only a few months before the rebellion was set to occur.
Emperor Cassian Ardel. The ruler of the empire who suspects me yet refuses to let me go.
Grand Duke Damian Kreutz. The man who knows he was used by me but persistently cannot let go of his lingering feelings.
Knight Commander Aiden Rosenberg. The knight who could discard even his honor and convictions to save me, while simultaneously monitoring me by the Emperor's order.
These were the figures who drove Duke Edelwein to ruin in the original story.
How will Guest survive?
