The Saturday–Sunday drama is scheduled to premiere on the 17th at 9:10 PM, and it’s already drawing attention as a late-1990s “end-of-century” retro office comedy. Set in the Yeouido securities district, the series focuses on Hong Geum-bo, an elite securities supervisor in her 30s who secretly enters the workplace again as Hong Jang-mi, a 20-year-old rookie employee.
Leading the cast is Park Shin-hye, who takes on the dual role. The newly released video highlights her visual shift between the two identities. Addressing viewers, she said, “Please look forward to it.” Opposite her, Go Kyung-pyo appears as the newly appointed CEO Sin Jeong-u, presenting a composed image through sharp styling. He added, “I am excited at the thought of meeting the viewers. I hope you watch it with interest, and I want to share the joy.”
The behind-the-scenes footage also features Ha Yoon-kyung (Ko Bok-hui) and Cho Han-gyeol (Albert O), both emphasizing their characters through distinctive outfits and fashion concepts. Choi Ji-su (Kang No-ra) and Kang Chae-young (Kim Mi-suk) introduce their roles as well, with costume styling used to define each character’s personality. The production notes show strong on-set chemistry among the ensemble cast.
Undercover Miss Hong plans to recreate the sentimental atmosphere of the late 90s using various props and delicate styling set against the backdrop of the Yeouido securities district. Key viewing points include the character relationships and the “womance” shared by the roommates of Room 301. Filming footage indicates a lively atmosphere, though not without the usual overlaps in dialogue and movement that come with ensemble scenes.
With its retro office setting, undercover storyline, and a cast led by Park Shin-hye and Go Kyung-pyo, the drama is positioning itself as one of tvN’s notable weekend releases this season. The first episode airs on the 17th at 9:10 PM, marking the official start of ‘Undercover Miss Hong’.
