The story of the upcoming drama "Ex Girlfriend's Club" focuses on the ex-girlfriends of webtoon artist Bang Myung Soo, played by "Misaeng's" Byun Yo Han. His exes both inspire and confuse him.

Bang Myung Soo uses his past dating life for inspiration and turns his ex-girlfriends into webtoon characters. The webtoon is a hit but when his exes realize they are in it they are not pleased. And if they like it even less when they learn that a producer, played by Song Ji Hyo wants to adapt the webtoon into a film. It's only after producer Kim Soo Jin decides to adapt the film that she realizes she is one of Bang Myung Soo's ex-girlfriends and that means she is also a character in the film.

But since Soo Jin's production company has financial problems she has no alternative but to continue with the production. Things get even more complicated when all the exes show up in one place.

Just who are Bang Myung Soo's exes?

Popular actress Song Ji Hyo will play Kim Soo Jin, ex-girlfriend number one. Song is best known for her roles in the drama "Emergency Couple" and the film "Frozen Flower" and her regular guest appearances on "Running Man."

Lee Joon Yi plays Jang Hwa Young, ex-girlfriend number two. She's a successful businesswoman, who works at an investment firm. Lee Joon Yi previously played Joo Ji Hoon's princess sister in "Princess Hours." She played a teacher in "Dream High" and appeared in "King 2 Hearts." She also had a leading role in the ratings winner "Wang Family."

Jang Ji Eun, who appeared in "Gu Am Heo Jun" and "Tree With Deep Roots," plays Na Ji A, girlfriend number three. She was Bang Myung Soo's first love but she married a rich man and subsequently divorced him.

Ryu Hwa Young plays Ra Ra, a not-too-bright but glamorous actress who happens to be ex-girlfriend number four. Ryu Hwa Young is a former member of the group T-ara and a rookie actress. She recently appeared in the film "Today's Love" with Lee Seung Gi and Moon Chae Won.

Byun Yo Han plays the brave, brazen and maybe totally clueless webtoon artist. Although he was cast in four films, including the 2015 film "Socialphobia," "Misaeng" was the actor's first drama.

"Ex-Girlfriends Club" begins filming at the end of March and will air in May after "Super Daddy yeol."
