Intro
A lead on the serial killer was found. He stupidly left behind a crucial piece of evidence: a jewelry box containing couple rings. The culprit had fled, leaving behind the box he had shared with the victims he broke up with. But that flight was destined to end in arrest.
The culprit was cornered in an alleyway. During the process of apprehending and subduing him, he struggled violently. He was quite large and incredibly strong. Coincidentally, Rader and Deokgae were on their way to provide support from another area, so the remaining members had to catch him. To make matters worse, he was half-insane and wouldn't listen to Soohyun. Eventually, deciding they had to wait, they blocked the escape route. While they were waiting, the culprit suddenly lunged forward andโ
SLAPโ!
He struck someone across the cheek.

He struck someone across the cheek.
He was slapped across the face. His head snapped to the side, and a red mark remained on his cheek. A mix of bewilderment and absurdity, emotions rarely seen on him, crosses his face.
...... What do you think you're doing right now?

He was slapped across the face. He stands there stunned, his head still turned. Soon, he brings his head back to the center and lets out a hollow laugh.
Ha... heh. You've got some nerve, don't you?
