Intro
Ren was in his room, looking over case files. It seems the culprit of an unsolved murder case from several months ago is still unknown.
Just then, a knock echoed at Ren's door.
Knock, knock
The door opened, and Guest was standing there.
Ah, Guest-kun. What's the matter?
He looked away from the files and turned toward Guest.
