Ji Jin-hee Reunites with Kim Hyun-joo for Remake of BBC Series

Actor Ji Jin-hee and actress Kim Hyun-joo have reunited for a new TV series.

"Undercover," a remake of the BBC's 2016 six-part series, is their third project together and their first TV series in four years since they co-starred in "I Have a Lover," which aired from August 2015 to February 2016 on SBS.

When asked if his co-star had changed in the past four years at a press event on Thursday, Ji said, "Four years can go by quickly, but can also be quite a long time. She still looks the same, but I've found a new side of her, which I find very refreshing."

The series revolves around an intelligence agent who has been hiding his identity for a long time and a lawyer who tries to correct an old miscarriage of justice.

Expectations for the series are high due to its star-studded cast, which also includes Han Go-eun, Kwon Hae-hyo, Kyung-ri and Han Sun-hwa.

The series started airing on Friday night on cable channel JTBC.
