Cheat on Me, if You Can

Yeo Joo, the famous crime novelist, spends her day locked up working on her new novel; her publisher needs her at her book concert.

Yeo Joo reminds Woo Sung of her power over him and the Disclaimer of Physical Rights that got her to agree to marry him.

The detectives continue investigating Baek Soo Jung's disappearance, but find it difficult to get their hands on the CCTV footage; the investigation into Soo Jung's disappearance gets officially underway; Soo Ho finds blood in Yeo Joo's basement.

Woo Sung is blackmailed and needs to come up with $50,000 by tomorrow, or else footage might leak of him entering Baek Soo Jung's studio.

Woo Sung gets taken to the hospital after almost drowning in the Han River; Yeo Joo races over to the hospital to see him after hearing about the accident and sees a person she didn't ever expect to see there.

Although the police have Yeo Joo as a suspect, she plays it cool and believes that they can't pin anything on her without a motive; the police have Woo Sung on camera entering Baek Soo Jung's studio apartment.
