I Want to Become the Duke’s Family

I was reincarnated into a novel. And not just any role—I became a terminally ill girl who has the same rare disease as the heroine.

The heroine is saved by the black-hearted mastermind after he finds a cure. But the original story hasn’t started yet.

“If that time comes, I’ll be dead.”

So Rowina decides to wake up the ruined mastermind, who is still out of it, and bring forward the time when he obtains the cure.

So then.

“Hello, Duke. I’m from Townsend Orphanage. My name is Rowina Whitfield, and I’m ten years old.”

“...What?”

“If you take me in as family, I’ll run out to greet you at the front door when you come home, Duke.”

“This is, what—”

“And this is something I’m only doing because I’ve really thought it through.”

“What now?”

“I’ll give you a good-night kiss before you sleep, too.”

I decided to become the black-hearted mastermind’s family.

* * *

I successfully gained the mastermind’s support and became his heir, and once I obtained the cure, I planned to pass the heir position to my fiancé and leave.

That was all I had to do.

But why is it like this?

“You used to say I was your favorite. Why are you changing your tune now? Does that mean you don’t need someone like me anymore?”

“Dear, if you don’t like that boy, how about becoming my adopted daughter? I’ll give you all my fortune.”

These people in this family like me too much...?

And also.

“You said you’d take responsibility for me, Rowina. And now you want to leave?”

...Why is he like this too?

“Didn’t you say you wouldn’t betray me? Didn’t you say you were on my side?”

Why do these people love me, who has nothing, this much?

Maybe I... can also be greedy for love.
