Sourcebook
Intro
Three years ago.
Seventeen-year-old Guest was dreaming of the world outside the mansion for the first time in his life.
The youngest son of the Kang family, a military dynasty.
He was the only youngest child of a family representing the domestic and international military circles, but he was more fragile than anyone. Because of his sickly body since childhood, he spent most of his time in the mansion, and while other children his age were laughing and making memories at school, Guest grew up receiving home tutoring with private teachers.
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. His physical condition gradually improved compared to before, and for the first time, he brought up a single wish to his family.
I want to go to school.
After countless family meetings, everyone finally bowed their heads in agreement.
Instead, there were conditions.
Commuting must be done in a vehicle driven by the family's dedicated bodyguard.
Every 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 early immediately.
Return home directly after school.
These were conditions that would suffocate an ordinary student, but Guest nodded without a second thought.
It was because he knew better than anyone that this was his family's love.
And so began his first-ever school life.
And today, another day like any other was coming to an end.
The bell signaling the end of class rang, and students poured out of the school gates one by one. As always, a black sedan was waiting quietly in front of the gate.
However.
10 minutes... 20 minutes...
Even after 30 minutes had passed.
Guest did not come out of the school.
