Choi Yoon Ji Confirmed as Lee Jong Suk’s Leading Lady in Iseop’s Romance
Choi Yoon Ji has officially joined the upcoming romance drama Iseop’s Romance as the female lead opposite Lee Jong Suk, adding a new name to one of the most anticipated K-drama projects currently in development.
On August 11, News1 reported that Choi Yoon Ji had been cast as Kang Min Gyeong, the female lead of the upcoming drama. The production company ACE FACTORY subsequently confirmed her appearance, stating that Choi Yoon Ji will be joining Iseop’s Romance.
Choi Yoon Ji Joins Lee Jong Suk
In Iseop’s Romance, Choi Yoon Ji will portray Kang Min Gyeong, a talented employee known as the “secret weapon” of TK Group.
She will star opposite Lee Jong Suk, who was previously confirmed to play Tae I Seop, a third-generation chaebol heir who appears to be perfect at everything except romance.
The drama will follow the office romance between Tae I Seop and Kang Min Gyeong, whose exceptional abilities at work make her one of the most capable people within TK Group.
The series is based on the popular web novel of the same name by Kim Eon Hee.
What Is Iseop’s Romance About?
Iseop’s Romance tells the story of Tae I Seop, a third-generation chaebol heir who excels in almost every aspect of his life but struggles when it comes to love.
His counterpart is Kang Min Gyeong, a highly capable employee whose performance has earned her the reputation of being TK Group’s “secret weapon.”
Their relationship will form the center of the drama, with the story combining an office setting with romance and the dynamics of a chaebol family.
Part of a Shared K-Drama Universe
One of the most interesting aspects of Iseop’s Romance is that the drama will exist within the same fictional universe as A Casual Lie.
Both dramas are adaptations of web novels written by Kim Eon Hee and are connected through TK Group.
While Iseop’s Romance follows Tae I Seop and Kang Min Gyeong, A Casual Lie centers on Tae Jun Seop, played by Lee Jun Hyuk. Tae Jun Seop and Tae I Seop are cousins, meaning the two dramas will share connections despite telling separate stories.
The two projects are being developed as interconnected productions, making Iseop’s Romance more than just another standalone romance drama.
Choi Yoon Ji’s Growing Career
Choi Yoon Ji made her acting debut in 2024 with Love Your Enemy and has since appeared in projects including The Trunk, Resident Playbook, Love, Take Two, and The WONDERfools.
Her casting in Iseop’s Romance marks another major step in her growing career, as she prepares to take on her first leading role opposite an established star such as Lee Jong Suk.
She is also set to appear in the upcoming second season of Disney+’s Moving.
When Will Iseop’s Romance Premiere?
Production for Iseop’s Romance is scheduled to begin this year, with the drama currently targeting a 2027 premiere.
A specific premiere date and detailed broadcasting schedule have not yet been announced.

Lee Jong Suk and Choi Yoon Ji’s New Romance
With Choi Yoon Ji now officially confirmed as the female lead, Iseop’s Romance has completed another major piece of its casting puzzle.
The combination of Lee Jong Suk as the seemingly perfect chaebol heir and Choi Yoon Ji as TK Group’s highly capable “secret weapon” is expected to bring a new dynamic to the office romance genre.
The drama's connection to A Casual Lie also gives the project an additional layer of anticipation, as viewers will eventually be able to see how the two stories and their characters connect within the same universe.
