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

The bidding and intrigue reach a thrilling, fatal conclusion.

Escaping danger, Juyoung and Hyungsoo arrive in the janitor's room where Juyoung tells the story of her past.

The first floor's exits are all blocked so 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 auction room is in complete mayhem. Juyoung attempts to negotiate with Heesook, suggesting that they kill the boss and escape together to no avail.

Six hidden bidders show themselves. They become more suspicious when they learn more about Hyungsoo.
