The actual killer was the cook at the first crime scene. While the investigation initially focused on Yoon-Suh and later identified Kyung-Yoon's girlfriend as the killer, it was ultimately revealed that the cook killed both victims. The cook had fallen in love with a singer who was also involved with one of the victims, and he killed the rapists and the singer herself, confessing his feelings as he murdered her.

Foreshadowing: The discovery of a secret passage leading from the first crime scene to the kitchen hinted at someone within the domestic environment being involved.

Yoon-Suh was subjected to severe abuse and rape by the three men who would later become the murder victims, two wealthy entrepreneurs and Jong Ha. This trauma led to his suicide attempt before he could be discharged from the service. The abuse was a direct result of Kyung-Yoon telling Yoon-Suh to 'man up' after protecting him from bullies, which inadvertently led Yoon-Suh to join the military where he became vulnerable to his attackers.

Foreshadowing: Flashbacks showing Kyung-Yoon's childhood protection of Yoon-Suh, followed by his painful instruction to 'man up,' foreshadowed the tragic chain of events that would unfold.

Kyung-Yoon believed Yoon-Suh had undergone a sex change and become the killer because of his repressed romantic feelings for his childhood friend. Driven by guilt over his past treatment of Yoon-Suh and his buried attraction, Kyung-Yoon projected his own unresolved emotions onto the investigation, incorrectly theorizing that Yoon-Suh was seeking revenge. This suspicion was further fueled by Yoon-Suh's sister Lee Hye-Seo refusing to confirm or deny the sex change claim.
