Young-won and Sa-kang shift Ji-eun to Honghak Hospital, which is just a stone's throw from their vacation home. Together, they brainstorm every conceivable scenario of what could've befallen Ji-eun and Jae-jin. While Young-won harbours suspicions about her mother-in-law due to the odd occurrences of late, she deems it crucial to join forces with her to locate Jae-jin first.

Young-won is solely focused on her son, Sa-kang is always thinking about what's best for her son, and Ji-eun is determined not to lose Jae-jin. With all these obsessions under one roof, Young-won's family begins to fall further apart. Adding to the turmoil, So-yi visits Young-won, revealing she is pregnant with Do-hyun's baby. Young-won realises it's time to confront Se-na directly to protect what's left of her family before it’s too late.
