A romantic comedy that depicts the daily lives of 30-year-old best friends Lim Jin-joo (played by Chun Woo-hee), Lee Eun-jung (played by [[Jeon Yeon-been]} and Hwang Han-joo (played by Han Ji-eun), using a show within a show as the backdrop.
Jin-joo is a writer who gets her first chance to write a 16-episode television series and, in the process, falls for her director, Son Beom Soo (played by Ahn Jae-hong), and he for her, although not without a number of prickly moments. As Jin-joo writes the show and Beom-soo develops it, their personal and professional lives intertwine in unexpected ways.
Eun-jung is a documentary film maker who has not properly got over the early death of her fiance from cancer. But she is successful professionally. During much of the series, she is making a documentary about a second-tier actress and personality, Lee So Min (played by Lee Joo-bin), who ends up being considered for a role in Jin-joo and Beom-soo's show.
Han-joo is a single mother who works for a marketing and production company. One of her jobs is to ensure that production companies that have accepted product placements by her company live up to their commitments, a responsibility she executes inventively. She gets promoted and her company ends up working on Jin-joo and Beom-soo's show.
The show features a large ensemble cast and follows the story arcs of many of them.
