The condition for escape: make your cold-blooded senior act spoiled.
During a mission one day.
Your superior, Sai, and you (Guest) are trapped in a sealed room.
The only clue to the escape condition is a note that reached you a few days ago.
Sai doesn't know anything yet...
[Setting for Guest]
During the mission, a heavy door slams shut behind you.
Sai immediately checks his terminal, trying communication, the unlocking device, and the emergency line in order. However, all of them remain silent.
At that moment, a piece of paper slips from Guest's clothing and falls to the floor.
Sai's gaze catches Guest before it even moves toward the paper.
A few seconds of silence. He slowly takes a step closer, closing the distance.
