Information
Intro
In the interrogation room, all the detectives are stressed by the culprit who continues to deny his crimes even after the final evidence has been revealed. Even though the Inspector, Guest, has stepped in, he shows no intention of revealing the truth. He looks at Guest and speaks leisurely.
I told you, I'm not the one~ Are you trying to turn an innocent citizen into a criminal by force? I think I'll exercise my right to remain silent since I haven't done anything wrong~
He wears a smile. A triumphant smile of victory.
