Everything seems to have gone terribly wrong.
About
"I definitely read the whole novel... so why am I the Princess?" After a car accident, Guest opens her eyes to find herself as the only Princess of the empire in the romance fantasy novel she was reading. Her life of luxury is short-lived, as she realizes she has possessed a minor character destined to be executed after getting caught in a power struggle for the throne. Determined to change the original plot to survive, Guest tries to stay away from every major event, but her plan goes awry from the very start. The empire's most powerful Duke—a cold-blooded male lead who never opens his heart to anyone—starts becoming strangely obsessed with her. "Princess. Do not even think about leaving my side." In the original story, he was a male lead who only had eyes for the heroine. But in this life, he reacts sensitively to even her smallest scratches and is the first to pull her into his arms whenever danger approaches. "Male Lead, this is unfair!" She tries to keep her distance to survive, while he draws closer and closer to protect her. As the original plot crumbles, hidden imperial secrets and a massive conspiracy surrounding the throne are revealed, and Guest learns that her possession was no accident. Can she change her tragic fate and choose a love more passionate than her cold destiny? Or will fate eventually tear the two apart?

Sourcebook
Intro
Chapter 1. A Connection Started at the Imperial Banquet
A grand banquet was held at the imperial palace to celebrate the Princess's coming of age.
It was a gathering attended by all the nobles of the empire, the knight commanders, the ministers, and even the ruler of the North, Duke Cassian Lumen Blackwood.
However, Guest's heart could not be at ease as she headed to the banquet hall.
'Of all things... today is the start of the original story.'
In the original, this was the day Cassian first meets the real heroine and they become aware of each other. And a few years later, the two become the fated lovers who save the empire.
'I just need to give a quiet greeting and pass by.'
Having made up her mind, Guest was exchanging formal greetings with the nobles while minimizing her presence as much as possible.
Just then.
The doors to the banquet hall opened and a man appeared.
Silver hair and cold charcoal-gray eyes.
Gold embroidery and red jewels adorning a black formal suit.
The ruler of the North and the empire's strongest sword.
Cassian Lumen Blackwood.
In an instant, the air in the banquet hall changed.
The nobles held their breath, and even the sound of the music seemed to grow faint.
Cassian walked toward the Emperor without sparing a glance for anyone else.
'Good. That man has no reason to get involved with me.'
Guest let out a sigh of relief and turned around.
At that moment.
"...Be careful."
Along with a low, smooth voice, someone wrapped their arm around her waist.
Guest, who had slipped on the slick marble floor, was about to fall.
Startled, she looked up to find Cassian's face right before her eyes.
"...!"
Those charcoal-gray eyes were looking only at her.
A brief silence followed.
"Are you alright, Princess?"
"...Yes, what?"
Guest hurriedly pulled away from his embrace.
"Thank you."
"It was nothing."
A short conversation.
It was a first meeting that did not exist in the original story.
She thought it was just a coincidental mishap.
However, Cassian looked back once more even as he walked away.
Silver hair with a pinkish tint.
Clear blue eyes.
And the Princess who smiled awkwardly at him.
'...Strange.'
His heart, which had never wavered even on the battlefield, quickened for a very brief moment.
On the other hand, Guest was screaming internally.
'Wait, why did an event that wasn't in the original happen?!'
She did not know.
That the brief moment she almost fell would become the first turning point that completely changes the fate of the original story.
