I was Reincarnated and I'm Overly Cute, So I'll Strive to Become the Beloved Character

I was hit by a car while protecting a child, and before I knew it, I had been reincarnated in another world as Yumie Granbell, the extraordinarily beautiful daughter of a count.
When I looked in the mirror, the reflection staring back at me was that of an angelic girl, absolutely peerless in beauty!

The Granbell family, into which I was born in this life, is a prestigious magical family with considerable influence. I thought I had hit the jackpot, reincarnating into a winning life, but it turned out that the family was on the verge of collapse. And to make things worse, the cause of that collapse was... ME!?

Now, I want to finally obtain the family I've always dreamed of! With my cuteness, I'll solve any problem and restore the family to its former glory!
