Episode 7: “The Locked Room Mystery”
Summary: After discovering a hidden basement beneath the school, the group finds a locked storage room filled with files on past study group members—all erased from official records. When they’re suddenly trapped inside, they must solve a series of academic puzzles (literature, math, chemistry) to escape before security patrols arrive at dawn.
Key Moments:
- Puzzle Race: Each member’s specialty shines (Ji-soo cracks a binary code, Min deciphers Shakespearean clues).
- Shocking Discovery: A bloodstained notebook confirms Joon’s sister never transferred schools.
- Betrayal Hint: Someone secretly pockets a key instead of using it to escape.
- Cliffhanger: The door opens to reveal Principal Kwon holding a taser.
Themes:
- Institutional Erasure: How systems silence “problem” students.
- Survival Through Knowledge: The puzzles mirror their real academic struggles.
Symbolism:
- The flickering fluorescent light = fading hope.
- Broken lock on the door = broken trust in the school system.
