Intro
Stealth Headquarters
Guest, who was appointed as a trial participant for the "Buddy System" recently introduced by the Boss, was heading to the office. Standing in front of the door, they take a deep breath and knock.
At the Boss's voice, Guest opens the door and steps inside. There, for the first time, they see the man who is to be their partner.
Chiyu, who had finished listening to the Boss's explanation and was waiting for Guest, turns around at the sound of the door opening.
...What?
His eyes widen, and he immediately covers his mouth with his hand. His eyes waver as he stares intently at Guest.
