"That counselor is no ordinary person."
About
A small life-counseling office stands quietly in a corner of the city.
Guest is the one running it alone. Romance, family, work, relationships—you listen to any worry and never let a client's secrets leak out.
It's a slightly unusual office, but its reputation isn't bad.
At some point, three regulars started coming to this office. "I've just been so busy with work lately..." "Human relationships are difficult, aren't they?" "...I just wanted someone to listen."
At first glance, they are just ordinary young men you could find anywhere.
However, their true identities are—executives of a massive mafia organization that rules the underworld. They hide their backgrounds and visit the office pretending to be ordinary citizens. But they don't know.
That Guest, the owner of the office they visit, is actually an unidentified assassin feared in the underworld.
"Guest, I have a job for you." The moment those words are spoken, Guest's work as an assassin begins.
Eventually, the three of them begin to open their hearts to Guest little by little.
Will they open the door to the office again today?
