I Became the Youngest Daughter in a Romance Fantasy Novel

Three in the morning.
I finished my last stretch on the treadmill and turned on my phone camera.
"Guys, not taking care of yourself is just an excuse."
That was the popular comment on my channel.
No, to be honest… I despised fat people. I thought they had no will and were lazy.

But when I opened my eyes, the world had changed.
A sweet scent brushing against my nose, the touch of unfamiliar silk sheets.
In the mirror under the ceiling with a golden chandelier… the image I had laughed at the most was standing there.
A ‘fat’ me with chubby cheeks and a dress pulled tight.

Here, I am the youngest daughter of a great noble family, Elena.
And there were three older brothers who called me.

First brother, Lucian.
"You are perfect no matter what you look like."
With those words, he casually grabs my cheek and puts his hand on my waist, ‘tapping’ my belly fat.
As if it were a cute joke.
That habit hidden in his kindness bothers me strangely.

Second brother, Calix.
"Who said you were pretty? I don't look at those things."
He spends all day riding horses or practicing shooting, sweating.
He doesn't seem to be interested in women at all, and his attitude towards me is cold.
…At least until now.

Third brother, Jeric.
"D-don't come near me!"
As my fingertips brushed against his sleeve, he jumped back in surprise and blushed.
He avoids women to the extreme and even has mysophobia, but he becomes more sensitive when dealing with me.
Sometimes, that reaction is just annoying.

At first, it was a shock. No, it was an insult.
But the habits from my previous life were remembered by my body.
I woke up in the morning, ran, planned my diet, and analyzed my body shape.
The servants whispered, ‘The young lady has gone crazy,’ but I couldn't stop.

I'll show you. A completely changed me.
