Choi Yoon Ji has exited the K-drama Iseop’s Romance after Lee Jong Suk’s September 3 departure, forcing a recast of both leads. The office romance, based on a popular web novel, is set to premiere in 2027.
Choi Yoon Ji’s exit from Iseop’s Romance marks a major setback for the upcoming K-drama, which had positioned the actress and Lee Jong Suk as its leading pair.
