A-rang agrees to do the alumni interview as Hee-jin asked him to. Seeing Hee-jin getting closer with A-rang, without knowing, Jae-yeol is concerned about Hee-jin and tells Hee-jin that A-rang isn't a nice guy. Meanwhile, A-rang wants to see Hee-jin in private, and he invites her to his studio.

After checking the conversation between A-rang and Ji-young, Jae-yeol runs to Hee-jin, worrying that she would be fooled by bad guys again. However, Hee-jin thinks what Jae-yeol does is cross the line and doesn't listen to him. Out of concern, Jae-yeol asks Ji-won for help. Meanwhile, Hee-jin finally gets to see the real side of A-rang.

Hee-jin tells Jae-yeol what happened that night, thinking he would be embarrassed about it. However, Jae-yeol doesn't get startled by it, and he confesses his feelings again. Hee-jin is still in doubt, but unexpected events make her think about him again. Meanwhile, Yeo-reum, who is a popular sports announcer, comes to school, and it seems like she and Jae-yeol have a history.
