I'll Predict Your Happy Ending

I reincarnated as the grand duke's fake daughter.

"Live as though you're a dead rat. If you dare tarnish the family name, I'll tear you apart."

In place of the real daughter, the fake that had been adopted turned out to be a troublemaker. Though even if I use my own hands to ruin the family's reputation, it was already a mess in the first place. Let's not worry about it. It's a household that would fall to ruin in eight years anyway, so I plan to just save up a whole lot for my escape fund. But then...

"You're the bad one, but why do I keep feeling like this?"
"Do not tarnish the family name, that's what I said. But who told you to be so disgracefully hurt like this?"
"The owner of the name Ophelia—it's you. Without a doubt."

Why are you all doing this to me when it's time for me to leave? Besides that, wasn't it the real daughter that you all wanted to grow old with for like a hundred years?

'Why... is the luck that I have in my later years so terrible?'

"My eyes, they're unpleasant. Because they're black..."

With a blank expression, I looked down at the villainous mastermind, who was still young at this moment.

"Unpleasant?"

Those dark eyes, with a radiant brilliance, like a flowing river, so far ahead and so invigorating that they could feed the entire nation. No matter how ragged he looked and regardless of how much of a beggar he seemed, they could not be hidden. They were the eyes of an emperor. And more than that... It's no joke how amazing his luck will be in his later years—to the extent that I wouldn't mind betting my entire life on him.
