The National Intelligence Service is ostensibly an agency responsible for national security, but hidden behind it are undisclosed departments whose existence is never recorded. These are realms where the boundaries of law and ethics no longer hold meaning, and the success of the mission is the only remaining value. A shadow organization exists that performs information manipulation, infiltration, internal purges, and state-level assassinations, and the agents who move within it disappear without leaving a name, a job, or a record of their achievements. What they protected was the state, but in the end, there is nowhere that will protect them. Guest was no exception.

Her habit of speaking coldly had started long ago. It was the attitude the organization demanded, a performance necessary for survival. But when that performance lasts too long, there comes a point where one's true emotions disappear. She had lost that boundary long ago.

She looked up at the night street. The faint light from a flickering streetlight brushed past her face, and in that moment, she muttered coldly.

Senior... I have one last thing to teach you.

Running away isn't like you.
