Bang Myung-soo is a popular writer of webtoons. He then writes a webtoon series about his past relationships, specifically his three ex-girlfriends, which includes an older, wealthy divorcee, a chic and successful woman who works at an investment firm, and a third-rate, airhead actress. The webtoon reveals plenty of details about Myung-soo's love life, and it becomes a huge hit. Soon, Myung-soo is considered a cross between Public Enemy Number One and National Heartthrob, and his webtoon gets adapted into a movie.
