Just when fans thought they had their dream office-romance pairing locked in, “Iseop’s Romance” has hit a major casting shake-up. With both its leading man and leading lady now stepping away, the highly anticipated drama is heading back to square one on casting.
What Happened with Iseop’s Romance?
On September 11, Choi Yoon Ji officially withdrew from “Iseop’s Romance,” according to a News1 report. The reason cited was a scheduling conflict — changes to the production timeline made it impossible for her to coordinate with previously committed activities.
A tvN representative confirmed the news directly, simply stating that Choi Yoon Ji stepped down due to scheduling issues. Her agency PEACE echoed this, explaining that after discussions with the production team, they mutually decided she would no longer participate in the project.

A Second Blow for the Drama
This isn’t the first casting setback for “Iseop’s Romance.” Just over a week earlier, on September 3, Lee Jong Suk had already announced his own departure from the project, also citing scheduling conflicts. With Choi Yoon Ji now following suit, the production team faces the unusual challenge of recasting both lead roles simultaneously before filming even begins.
What the Story Is About
Based on a popular web novel, “Iseop’s Romance” follows the workplace romance between Tae I Seop, a third-generation chaebol heir at TK Group who’s brilliant at everything except love, and Kang Min Gyeong, a fellow new employee whose performance actually outshines his. It’s a premise that leans into the popular Korean drama trope of workplace power dynamics colliding with unexpected romance — a formula that has consistently resonated with audiences across the genre’s history.
Lee Jong Suk, known for his extensive filmography spanning both film and television since his breakout roles over a decade ago, would have brought considerable star power to the male lead, making his exit a notable loss for the production regardless of the reason behind it.
What Happens Next?
Despite these back-to-back casting changes, the production team hasn’t signaled any delay to the broader timeline. “Iseop’s Romance” is still slated to begin filming this year, with a premiere planned for 2027 — though naturally, the search for new leads will now be a top priority before cameras can roll.
