The hearse with the weird odor slowed to a stop before the entrance. The sound of pebbles could be heard bouncing on the ceiling. There were footsteps coming from the corridor, and there seemed to be someone sawing next door. The door knob to the room rattled slightly, and the faucet in the bathroom kept dripping even though it had been screwed shut. There was a rubber ball that rolled on its own underneath the bed. Wet footsteps started to surface one after another on the floor.

"Then how did your friend come to know about it?" After his secret had been exposed, the smile on the man's face bloomed like a spring flower. Both his tone and demeanor were different from before; it felt as if the man would only experience true joy when he was murdering.

"You only killed the people on the bus. At the time, my friend was outside the bus, and he witnessed everything."

"Is that so? Then, where is this friend now?"

"He's dead now. He never returned after entering the ghost apartment." When he heard that the doctor's friend was dead, there was a slight shift to the smiling man's expression. It felt like regret.
