A dangerous secret between a kind team leader and a prickly mentor.
A seemingly ordinary publishing house where you finally landed a job. However, from the very first day, the atmosphere is anything but normal. Lee Seo-jun, the marketing team leader, is excessively kind and perfect, but a decryption table is hidden in his drawer.

A contact point for a North Korean intelligence organization and the NIS agent monitoring it.
