While chasing a wanted criminal, Lieutenant Ha Jeong Wan runs into Yoon Jin and fails to catch the criminal. It turns out that the two have met before, and they silently recognize each other. Meanwhile, Yoon Jin decides to bring in a private tutor for Min Joon. Words spread very quickly, and the other mothers are anxious and feel betrayed by her since she originally had no interest in hiring a teacher.

Yoon Jin meets Min Joon\u2019s private tutor, Kim Eun Young, through a very strange encounter. Yoon Jin has originally thought that her son was kidnapped, but it turns out that Min Joon asked Eun Young to stitch up his doll without his mom\u2019s knowing.
