Juyoung and Hyungsoo meet for the first time in room 506; Hyungsoo bargains the price for Juyoung and goes into the bathroom; Juyoung makes a peculiar phone call with someone and tells Heesook about the appointment.

The auction room is in complete mayhem; Juyoung attempts to negotiate with Heesook, suggesting that they kill the boss and escape together to no avail.

The first floor's exits are all blocked; Juyoung breaks through the emergency exit and disappears alone; Hyungsoo makes it to the second floor with Geukryul's help; they desperately run for their lives from Mr. Min and Bookwan.

The six bidders who'd been hiding in the storage room show themselves; when they learn that Hyungsoo is a detective, they become more suspicious.

Once they escape the storage room with the bidder, Juyoung and Hyungsoo arrive in the janitor's room and watch a Koryo-saram die; as she takes the gun, Juyoung tells the story of her past.

Juyoung kills the boss and Hyungsoo kills Heesook; they find a safe with morphine; they also find the safe with cash with Geukryul's help; after packing up the money and morphine, Hyungsoo and Juyoung leave Geukryul behind.
