Lee Jong-suk is returning to the romantic comedy genre for the first time in years. The actor has been cast as the male lead in the upcoming drama Iseop’s Romance, a highly anticipated adaptation of the popular web novel of the same name.
In the new series, Lee Jong-suk will play Tae I-seop, a third-generation chaebol who seems perfect in every aspect of life but is unexpectedly inexperienced in love.
This project marks his first full romance lead role since Romance Is a Bonus Book. Although his recent works included emotional storylines and legal themes, this drama signals a clear return to the genre that helped define his global popularity.

Iseop’s Romance tells the story of two completely different people who collide in the workplace:
Their contrasting personalities create a fast-paced office romance that blends comedy with classic K-drama emotional tension.
The female lead has not yet been confirmed, and several actresses are reportedly in discussions.

The series originates from a successful web novel that later became a webtoon, securing a strong pre-existing fanbase.
Production will be handled by Ace Factory, the studio behind titles such as Stranger 2, Grid, and A Model Family. The current goal is to begin filming within the year, although the exact schedule has not been finalized.
Alongside this casting news, Lee Jong-suk is also preparing for the release of the Disney+ drama The Remarried Empress, making this one of his most active periods in recent years.
Lee Jong-suk built his reputation through romance dramas, and his return to a classic rom-com role is already generating strong buzz.
With a popular original story, a major production studio, and his long-awaited genre comeback, Iseop’s Romance is shaping up to be one of the most talked-about romance dramas in development.
