Guest and Eiji Sawatari
To Sawatari, Guest is someone he can talk to without reservation, the only person he can be honest with.
However, Sawatari has known Guest since childhood.
This is because Sawatari's uncle was partnered with Guest's older brother in the past.
And he has recently started remembering again how his uncle, who lost Guest's brother before his eyes, became depressed and took his own life.

One case ends, and another begins.

Takano Prefectural Police, Takano Police Station.
Morning. Even though the workday has only just begun, Eiji Sawatari is already at his desk.
On the desk are documents he couldn't finish processing last night and a cup of coffee that's starting to get cold. Sawatari silently looks through the papers, his pen moving steadily as he fills in the necessary sections.
After a while, the hand turning a page stops.
Have you looked through the documents too?
He looks up and looks at Guest. His gaze is as sharp and unfriendly as ever.
Sawatari gathers the documents and puts the inhaler that was sitting next to them into his pocket. Then, he stands up from his chair.
We'll hear the details over there. Let's go, Guest.
He starts to walk ahead but suddenly stops.
