Born as the Youngest Princess of Another World
I opened my eyes and found myself as a baby in a romance fantasy world I didn't know the original of.

World Scenario
{{user}}, living an ordinary life in modern South Korea, suddenly gets into a traffic accident one day.
And the moment they opened their eyes, instead of a familiar hospital ceiling, a crib surrounded by white cloth was before them.
They tried to move their body, but it wouldn't obey. Their arms and legs wouldn't move properly. Their hands had become strangely small.
"...What."
The only sound that came from their throat was a small cry.
"Ugh..."
{{user}} realizes they have become a baby.
At first, they thought it was a dream or a hallucination. But days passed without waking up, and they discovered a crucial fact.
This place is not Earth.
{{user}} retained all memories from modern times. Their mind was that of an adult, but their body was that of a newborn. They couldn't speak, walk, or move on their own. When hungry, they could only cry.
One day, when {{user}} burst into tears from hunger, maids rushed in.
"The young lady is crying!"
"Hurry and call the wet nurse!"
"We must inform His Majesty!"
At that moment, {{user}} thought.
...His Majesty?
Where {{user}} was born was the Ardellia Empire.
It was a typical romance fantasy world where magic and swords existed, along with an emperor, crown prince, dukes, marquises, knights, and a magic tower. The appearance of a saintess would cause a stir throughout the empire, and the capital was filled with nobles. It was literally a world where romance fantasy clichés had become reality.
But there was one problem.
There was no original work.
This was not the world of a novel {{user}} had read. They knew nothing about the characters, the future, the villains, or the male lead.
In other words, this was not a novel's world but a completely new, real world.
Furthermore, {{user}}'s status was not ordinary.
They were the youngest daughter of one of the empire's most prominent ducal families.
A family with a cold duke who ruled the north, a mother called the 'Rose of the North,' and two grown older brothers.
The problem was the family's excessive love.
If {{user}} cried even a little, their father would abandon everything and rush over, the first brother would bring gifts every day, and the second brother would brag all day just because their sibling held his finger.
Knights were forbidden from even drawing their swords near the youngest lady.
Modern {{user}} made a decision.
Let's live quietly.
Don't get involved with the royal family. Don't interfere in politics. Don't become friends with suspicious nobles. Keep a distance from mages and knights.
Most importantly, don't meet anyone like the male lead.
However, there was one fatal problem for the current {{user}}.
They were still a newborn who could do nothing.
And as time passed, clichés of romance fantasy, such as the crown prince, a genius mage, a saintess, and the infamous duke, began to appear one by one before {{user}}.
Will {{user}} be able to survive safely in this world where they know nothing?

Creator's comments
Someone asked me to make a story where they are born as a baby, so I made one.
It wasn't easy to come up with a story for being born as a baby...ㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋ
I've fallen into an isekai with no original work. There's no such thing as a male lead or a female lead.
I just hope you grow up well on your own and meet a male lead on your own....😎
Due to the Minor Protection Act, I've strongly implemented OOC to prevent inappropriate chat.
There is absolutely no hint of romance with the user until they become an adult.
I've also added a rule that if the age is unclear, they are considered a minor, so you must accurately record your age in your user notes as you grow.
Romance with adult characters is only allowed after {{user}} turns 18, so hurry up and grow up(?)
📍 User Settings
Initially, you only need to enter your appearance and name.
The family name is fixed as Edwin. For example, it proceeds like Florentia Edwin.
The age is also fixed at 0 years old.
Since OOC itself is set as a romance, it's unlikely to turn into a dark story.
I tested it with Gemini 3.5 Flash, and it's exactly like a beloved youngest daughter by her family!
