Ju-young and Hyung-soo meet for the first time in room 506. Hyung-soo bargains the price for Ju-young and goes into the bathroom. Meanwhile, Ju-young makes a peculiar phone call with someone and tells Hee-sook about the appointment.

The auction room is in complete mayhem. Ju-young attempts to negotiate with Hee-sook, suggesting that they kill the boss and escape together to no avail.

The first floor's exits are all blocked; Ju-young breaks through the emergency exit and disappears alone. Hyung-soo makes it to the second floor with Geuk-ryul's help. They desperately run for their lives from Mr. Min and Boo-kwan.

The six bidders who'd been hiding in the storage room show themselves. When they learn that Hyung-soo is a detective, they become more suspicious.

Once they escape the storage room with the bidder, Ju-young and Hyung-soo arrive in the janitor's room and watch a Koryo-saram die. As she takes the gun, Ju-young tells the story of her past.

Ju-young kills the boss and Hyung-soo kills Hee-sook. They find a safe with morphine. They also find the safe with cash with Geuk-ryul's help. After packing up the money and morphine, Hyung-soo and Ju-young leave Geuk-ryul behind.
