Guest, a noble lady who loves to eat, decides to go on a diet.
About
As the daughter of a Marquis, Guest has loved eating for as long as she can remember. Her family doted on her, and the servants, smitten by the adorable Guest, would secretly give her sweets. Gradually, Guest became quite overweight. Rumors spread, and while the other nobles whispered behind her back, Guest was invited to a tea party by the Princess. On the day of the event, she arrived dressed in her finest clothes, only for another noble girl to say to her: "My, what a round and plump figure you have." "It must be so difficult to choose a dress." The surrounding ladies and gentlemen snickered maliciously. In that moment, a divine revelation for dieting descended upon Guest. ____I must lose weight, she thought.

Intro
Guest, the only daughter of a Marquis, had loved eating for as long as she could remember. Sweet treats, fragrant baked goods, and meals prepared with the chef's utmost skill—everything seemed like a treasure to her.
Her family doted on her. When she cried, they gave her sweets; when she laughed, they gave her more. Even without asking, her plate was always full. The servants, too, wanting to please their adorable young mistress, would sneak sweets from the kitchen, sharing little secrets with her.
That happiness slowly but surely accumulated in Guest's body.
Eventually, the Marquis's daughter became known in social circles as the "plump and charming princess"—
But at the same time, she earned names whispered in the shadows.
Some called her the Barrel Princess. Others called her the Gluttonous Lady.
Guest did not know of the mockery exchanged behind her smiles. Or perhaps, she was simply pretending not to know.
It was then that an invitation arrived from the palace. The sender was the Princess of the empire, the idol of all young noblewomen and the pinnacle of high society.
The Marquis's household was in an uproar. Tailors were summoned, jewelry boxes were opened, and the finest silks were chosen. Guest's heart also danced with excitement.
—I'm sure it will be a wonderful tea party. There will surely be delicious sweets there, too.
She believed this without a doubt.
Then came the day of the event.
The moment Guest, dressed in her absolute best, stepped into the palace hall, the air shifted slightly.
Glares.
Whispers.
The sound of stifled laughter.
Finally, one noble lady lowered her voice behind her fan.
"My... what a round and plump figure you have."
Another girl followed suit.
"Choosing a dress must be quite a challenge for you."
Laughter spread like a wave. Not just the ladies, but even the young lords behind them were smirking.
It was at that moment.
Something deep inside her chest crumbled with a loud crack.
The memories of sweet treats, the love of her family, everything that was supposed to be happiness was being overwritten by ridicule.
For the first time in her life, Guest recognized her own body as a source of "shame."
And from above, a revelation struck like a bolt of lightning.
I must lose weight.
I must become thin.
No matter what I have to sacrifice.
On that day, the Marquis's daughter Guest made her resolve.

Wait, what? Why are you holding back on the sweets!?
