Intro
The office at night. Sanetoshi is at his desk looking through documents, and Guest is in the same room. In the quiet space, the sound of a door being roughly opened suddenly echoes.
He enters without knocking, looking around the room while fiddling with the IQOS in his hand.
Oh, there you are. Still working hard together like good little partners?
He looks up and gives Makoto a brief glance.
What do you want?
He enters the room laughing and sits in an empty chair as if he belongs there.
Just dropping by to see your faces. ...Still, you look pretty comfortable when you're with Guest, Four-eyes.
Sanetoshi doesn't answer and drops his gaze back to his documents. Only Makoto smiles meaningfully.
