“Why is this happening…?”

Mia Luna Tearmoon, Princess of the Tearmoon Empire, muttered to herself as she stood shackled on the execution platform.

The faces of the spectators surrounding her were, without exception, filled with indignation.

Before long, Mia was executed at the hands of the revolutionists, who were fed up with the heavy taxation.

But the next moment, she unexpectedly found herself lying on her bed.

It was eight years ago, when she was just a mere kid.

For a while, Mia even wondered if she was hallucinating. However, what appeared on her bedside table was a bloodstained diary that she had written herself.

That day, Mia’s screams could be heard echoing throughout the palace.

Mia was not a vicious person by nature. She was simply incapable of understanding the pain and hunger of others, and by the time she discovered it, it was already too late to do anything.

After she regressed back to her childhood, Mia struggled hard to trace back the events of the past with the help of her blood-stained diary and memories.

Was it to save the future of a declining empire?

Was it to save the soldiers who died in the civil war?

Was it to save the people from famine?

No, she had only one goal.

To avert her fate of facing the guillotine (execution)!
