18 Again

As 18-year-old Hong Dae Young, Ko Woo Young realizes that his children are living a life that he wasn’t aware of, and he decides to encourage them as a friend. In the meantime, Da Jung goes through blind recruitment at JBC. While having a night out with Ae Rin, Da Jung comes across Choi Il Gwon, a high school friend. On their way back home, Da Jung sees Woo Young whose appearance seems to overlap with that of Dae Young’s.

Da Jung gets a phone call from JBC regarding the results of the open recruitment. Meanwhile, Woo Young picks a fight with Ja Sung when he just won’t stop bullying Si Woo. On her first day at JBC, the fact that she is married dissatisfies the higher ups, resulting in a clearly biased treatment towards Da Jung. Later on, Da Jung gets a chance for an interview with only a few minutes left before going live.

While internet trolls attack Da-jeong with malicious comments, Ye Ji-hun's interest in her grows. Hong Si-a warns Gu Ja-seong to stop his ways.
