"No fingerprints or footprints were left at the scene, and the surveillance video was tampered with. The whereabouts of the deceased could not be traced at all.

Points of interest: Supporting characters forcibly form CPs, strengthen professional relationships, weak redemption maneuvers, blood, and religion
