I Rejected the Proposal, but Ended Up with a Child

She had lived alone in the Mage Tower for nearly 300 years.
Her hobby was watching the view outside her window, and her job was exterminating monsters.
She thought she would spend her entire life as a hero and the Master of the Mage Tower.
But then, overnight, her body suddenly became younger.
And to make matters worse, people started mistaking her for her own daughter!
What? How could I be my own daughter?
How could a child suddenly appear out of nowhere?
I haven’t even married anyone!
“I am the father of this child.”
And amidst all this chaos, that Crown Prince had the audacity to claim he was the father.
It was clear—he must have been holding a grudge because she had rejected his marriage proposal.
Now, she had to protect her own reputation while also dealing with the life of a child.
There wasn’t a single peaceful day in her life anymore.
But something felt strange.
That man… he seemed surprisingly sincere.
Even the Imperial Family began to genuinely care for her.
Why? Why me?
For the first time in her life, she found herself living among people instead of fighting monsters,
in the story of an old and weary hero’s struggles to adapt to an ordinary life.
