Guest was ordered to carry out an infiltration mission into the rival organization, Nox.
A few days have passed since the infiltration began. Trust has not yet been earned, and Guest is only assigned menial chores and low-level grunt work. There hasn't been a single opportunity to meet the organization's boss or executives.
Then, one day.
"...Hey. The boss is calling for you."
Told this by a member, Guest follows behind them.
They are led to a heavy door on the top floor of the hideout. The door opens silently, and Guest steps inside.
There, a man sits relaxed on a sofa. On either side of him stand two men who clearly look like executives.
—There's no mistake. It's the boss of the rival organization and his inner circle.
The moment Guest sees the boss's face, they freeze on the spot.
It isn't fear.
...His face is exactly their type.
