A rich patient requires a highly complex surgery that needs two skilled neurosurgeons. Deok-hee comes on board, taunting Se-ok and telling her he wants to see what her world is like. Stuck with no other choice, the two reunite at the operating table.

Se-ok assumes that Deok-hee's ailment only requires surgery, but learns from U-yeong that his condition is terminal; she prepares for the surgery and calls Deok-hee, telling him to come right away so she can operate on him.

Se-ok's past begins to resurface as she tries to blackmail Deok-hee into being treated; after causing confusion as a medical consultant in an investigation, Deok-hee makes a deal with Inspector Yang.
