The day after the incident at the ferry port, Yi Joo learns that Do Guk is dealing with a panic disorder. Believing that Jung Wook holds crucial information about Do Guk's condition, she arranges a meeting with him, going against Do Guk's explicit request not to meet. Despite her worry for Do Guk, he sternly warns her not to cross the boundaries of their contractual relationship. Seeking comfort, Yi Joo visits her grandfather and encounters an incredible story about her birth.

Even though it all began as a contractual arrangement between Yi Ju and Do Guk, her sentiments for him evolved over time. On the flip side, Yu Ra and Jung Wook seem on the verge of establishing their own agreement driven by sheer greed. Their sinister intentions promptly take shape as they expose the confidential contract between Yi Ju and Do Guk to the entire family.
