"Undercover High School" actor Seo Kang-jun shared his thoughts on appearing in a new work after four years.

On the morning of the 25th, Seo Kang-jun and Jin Ki-joo appeared as guests on MBC Radio FM4U's "Lee Seok-hoon's Brunch Cafe (abbreviated as Brunch Cafe)." The two talked about their current situation to listeners and shared details about "Undercover" in response to DJ Lee Seok-hoon's direction. They are currently starring as the male and female leads Jeong Hae-seong and Oh Su-ah, respectively, in the MBC Friday-Saturday drama "Undercover High School (abbreviated as Undercover)," which began airing on the 21st.

In particular, "Undercover" is Seo Kang-jun's first work after completing his military service. After returning to drama through "Undercover" four years after the series "Grid," which was released in 2022, Seo Kang-jun noted, "It's still awkward and burdensome. I wonder if it's really airing. I can't quite believe it."

In this regard, during the press conference for "Undercover," Seo Kang-jun revealed that he was unaware of the new terms that emerged during his hiatus. Seo Kang-jun said, "Do you know the term 'neujok'? It means 'feels good.' I just found out about it this time. I also heard 'bun-jok café' refers to a café with a good atmosphere, but honestly, I had no interest in the new terms, so I didn’t know much about them," which elicited laughter.

Seo Kang-jun also explained his reason for appearing in "Undercover," stating, "When I read the script, there were many genres like action, comedy, romance, and human themes, and they were skillfully combined. I thought it could get a lot of love from people, and there must be something to convey. I play a National Intelligence Service agent who infiltrates a high school. I'm in my 30s, but it's a concept like 'Two Fist Fighting'."
