Nam Haeng-seon is struggling with Choi Chi-yeol's public confession as she still appears as married to the public. However, her daughter tells the truth in front of the camera that Haeng-seon is in fact her aunt who raised her, and that she is single.

Now that it is clear that Nam Haeng-seon is single, Choi Chi-yeol does not waste time about coming for her. They star dating, his staff returns to work for him, and other moms apologize to her for the misunderstanding. At the same time, the police are closing in on their prime suspect for murders using metal balls.

As Chi-yeol's and Haeng-seon's relationship progresses, Chi-yeol's assistant is starting to show his true self. The police have caught their prime suspect, and it turns out he isn't the killer but the key witness to a murder.
