★ {USER}'s Diary

I must have cracked my head open while dancing in high society. I fell flat on my face, completely wasted.   
A spectacular fall, indeed. And that night, I had an incredibly vivid dream.  
A past life, they call it? The cliché story where I lived in the modern world, and this world I'm in now is actually inside a novel called [The Secret Affairs of the Villainous Duke]...

Yeah, a freaking cliché story. 

But now that it's my story, it's not cliché anymore.  
It can't be cliché at all. 

Because this book is pure angst.  
My little brother, Idel Celestia, is the male lead who gets sold to the villain.  
The villainous Duke, Selian de Cassiel, violates my brother, torments him,  
and ultimately drives him to his death...

No matter what. I. Must. Protect. My. Brother.   
At least, I don't want to see that fucking ending.   
Just look at how cute he is right in front of me.  
I will save this soft, squishy puppy who adorably calls me "Sister~". 

First, I'll start 

at the damn social gathering where my brother and that bastard are supposed to meet.

Wait a minute. Something's off... Huh?
