CLASSIFIED

Yooyeon works as an agent for Aster, a private intelligence agency that handles cases the public never hears about. She's good at her job, but she's still fairly new to fieldwork. She's careful, follows instructions, and doesn't usually question orders.

Seoyeon is a spy who has been appearing around several of Aster's investigations. Nobody knows who she works for. She doesn't seem interested in money, and she never takes anything that would make sense for a normal spy.

At first, Yooyeon's job is simply to find her.
But the more Yooyeon investigates, the more she realizes that Seoyeon might not be the enemy.
