Ex-Girlfriends' Club

Su-Jin faces difficulty as a movie producer and in order to her career, she decides to create a movie based on a webtoon story. However, she finds out that the writer of the webtoon is her ex-boyfriend.

Su-jin carries out her plans to make the movie with Myeong-su's webtoon, but runs into an unexpected problem with the writer's ex-girlfriends.

Myeong-su swears that he will carry out the movie plans after watching Su-jin undergo the most embarrassing moment of her life. However, his girlfriends stop at nothing to interrupt the movie from being made.

The ex-girlfriends find out about Myeong-su's fake scenario and on top of that problem, Hwa-yeong decides to withdraw her investment into the movie project.

Myeong-su is driven to the point of madness as he tries to balance writing a scenario, drawing more webtoons, and making sure his girlfriends don't create a problem.

Myeong-su and Su-jin act like a couple for the movie production but are found out by Geon, almost leading to the cancellation of the movie. Meanwhile, Myeong-su and Su-jin's relationship is further complicated with Geon in play.

Myeong-su's ex-girlfriends question his behavior around Su-jin as he showed to be different than normal. However, he denies all accusations to be untrue, but feels the need to share his true heart to Su-jin.

Myeong-su finally shares his feelings towards Su-jin, who is happy to hear his true feelings on one hand but is also bothered by the fact that she knows all his past relationships on the other.

After their major quarrel, Myeong-su and Su-jin find themselves closer to each other and decide to share their relationship with everyone else. Meanwhile, Hwa-yeong requests the ex-girlfriends to participate for the weeding photo.

Yeong-jae calls off the engagement and withdraws all investment from the movie after learning the truth. Meanwhile, Su-jin and Myeong-su try to help Hwa-yeong after the break-up.

Su-jin searches for new investors after the mishap and Geon tags along to help her. Myeong-su finds Geon's action to be a bother as he roams around Su-jin during this time.

Even though Su-jin finds both the boys arguing in front of her family exceptionally uncomfortable, She and Myeong-su decide to start a new relationship clean off the slate.
