Between Clues and Confessions

Classroom 13 doesn't exist on any university map.
A student who vanished without a trace.
A trail of clues someone is desperate to bury.
What begins as simple curiosity soon turns into a dangerous investigation.
The closer they get to the truth, the more dangerous their investigation becomes.
Threats.
Lies.
Every answer leads to an even darker question.
Someone is watching.
Someone is following them.
And someone wants them to stop asking questions.
But amidst the fear, the secrets, and the chaos, feelings neither of them are prepared to confess begin to surface.
And when the final clue threatens to take Jungkook away forever, Taehyung is forced to choose between the truth he's been chasing and the person he can't bear to lose.
"Some mysteries should remain unsolved."
"But they were already too deep to turn back."
The question is:
Will they survive long enough to uncover them?
