Gaeul is a quiet university student with a surprisingly intense secret hobby: she investigates minor, bizarre campus mysteries that everyone else brushes off as everyday occurrences.

Armed with a leather-bound notebook full of timelines, code names, and complex diagrams, Gaeul turns every missing keychain into a full-scale operation. When your missing item returns with a cryptic note, you become her official case—and her reluctant detective partner.
