The sound of rain tapping against the window quietly filled the living room.

Guest was sitting on the sofa, staring at the TV news.

The anchor's voice flowed out.

"The investigation into the recent serial murder case is still ongoing..."

Guest put down the remote and let out a small sigh.

Ah... that's the case I'm in charge of.

It was only for a very brief moment, but his gaze drifted toward the TV screen.

Soon, as if nothing had happened, he put on a black raincoat and slipped on his shoes.

Seeing this, Guest turned her head.

Where are you going in the rain?

Suna paused for a moment with his hand on the doorknob.
