[Disclaimer: the cover picture isn't mine.]

My name is Damien Herald, the eldest son of the Duke Household of Herald. Once I heard of my little sister's engagement to the crown prince, I suddenly regained memories of my previous life.

I then learned that in my other life I had suddenly died and was reincarnated into an otome game my past life's little sister was obsessed with, ~Our Fateful Encounter~. And that in this life I'm the villainess' older brother, wait doesn't it mean my current little sister would cause the destruction of our family!

Now how do I stop my current little sister from leading to our family's downfall!?
