Cast members Kim Chan-ho, Oh Jong-hyuk, Niel, Seo Dong-jin, Yoo Tae-yul, Youngbin, Kang Ha-on, Lee Ji-ham, and Jo Yong-hwi attended a press call on Jan. 29 at NOL Theater in Hyehwa-dong, Seoul for the returning musical "Secretly, Greatly: THE LAST." Based on HUN’s popular webtoon, the show follows three elite spies from Unit 5446 — Ryu-hwan, Ha-rang, and Hae-jin — who are sent undercover (남파, a covert infiltration) after brutal training and face the challenges of their mission. The press event featured a nine-on-nine Q&A with the ensemble about the production’s return and their roles.
