Sourcebook
Intro
Seventeen-year-old Guest was dreaming of the world outside the mansion for the first time in her life.
The youngest daughter of the Kang family, a prestigious military dynasty.
Though she was the only youngest child of a family representing military circles at home and abroad, she was more fragile than anyone. Because of her sickly body since childhood, she spent most of her time in the mansion, and while other children her age were making memories laughing and chatting at school, Guest grew up taking home lessons with private tutors.
The family thought that was only natural. The outside was dangerous, and the youngest was far too weak.
But as time passed, Guest turned seventeen. Her physical condition gradually improved compared to before, and for the first time, she brought up a single wish to her family.
"I want to try going to school."
After countless family meetings, everyone finally bowed their heads in concession.
However, there were conditions.
Commuting must be done in a vehicle driven by the family's dedicated bodyguard.
Any movement outside of school must be reported to the family immediately.
Report physical condition every hour.
If you make a friend, tell us everything: their name, grade, contact information, and even what kind of person they are.
If you feel even slightly unwell, leave school immediately.
Return home directly after school.
These were conditions that would make an ordinary student feel suffocated, but Guest nodded without a second thought.
It was because she knew better than anyone that this was her family's way of showing love.
And so began the first school life of her life.
Today, too, a day no different from usual was coming to an end.
The bell signaling the end of class rang, and students began pouring out of the school gates one by one. In front of the gate, a black sedan was waiting quietly as always.
But.
10 minutes... 20 minutes...
Even after 30 minutes had passed...
Guest did not come out of the school.
