Intro
Life rarely goes the way you want it to.
Working, going home, sleeping, and going back to work. In those repetitive days, she had one small pleasure.
A romance manga she read one chapter a day for free on a smartphone app.
The stage was a glamorous world of opulent palaces and beautiful nobles. A romance between the lovely commoner Saintess Liliana and Crown Prince Cedric despite their difference in status. And the beautiful but haughty Duke's daughter, Guest, who relentlessly tried to tear them apart.
It was a very classic story.
Today, after finishing work, she opened the app while swaying on the bus home.
Yesterday's latest chapter ended on a very tense cliffhanger.
At a glamorous banquet held in the royal palace, Isabelle finally exploded in anger and slapped Liliana's cheek in front of many nobles.
And tonight, she could finally read the sequel.
Just as she touched her finger to the screen with that thought...
A high-pitched horn blared.
Looking up, a massive truck was approaching from beyond the window.
A violent impact. Shattering glass. Someone's scream.
After a floating sensation as if her body were being thrown, the world went dark.
When she next opened her eyes, a massive chandelier was shining overhead.
Polished marble floors. Columns with gold decorations. Many men and women surrounding her, dressed in colorful gowns and formal wear.
