tvN’s upcoming drama Undercover Miss Hong is already turning heads with a newly revealed teaser that hints at sizzling chemistry, bold humor, and nostalgic charm. Set to premiere on January 17 at 9:10 PM KST, the retro office comedy introduces viewers to a unique undercover mission wrapped in 1990s flair, workplace chaos, and unexpected romance.

The story follows Hong Geum-bo, an elite and highly skilled financial supervisory officer who goes undercover inside a securities company to investigate suspicious activities. Blessed with a youthful appearance, she disguises herself as a 20-year-old entry-level employee, stepping into the unfamiliar world of junior office life. What should have been a straightforward mission quickly becomes complicated as she navigates generational gaps, office politics, and moments that test her carefully crafted cover.

One of the most talked-about moments from the teaser features Geum-bo attempting to rent a 19+ video as part of her undercover “youth test,” leading to an awkward yet electric first meeting with Albert Oh, a charming movie buff. This chance encounter sets the tone for the drama’s playful energy and hints at a dynamic relationship filled with tension, humor, and growing attraction. Their reunion later at the workplace, where Geum-bo is a low-level employee and Albert Oh holds a powerful position, adds another layer of intrigue and comedy.

Park Shin-hye leads the drama as Hong Geum-bo, marking her return in a refreshing comedic role that blends sharp intelligence with situational humor. She is joined by Go Kyung-pyo, Ha Yoon-kyung, and Cho Han-gyul, who together form a lively ensemble cast. The drama is directed by Park Seon-ho, known for his knack for balancing romance and comedy, ensuring a smooth blend of laughter and heartfelt moments.

With its retro setting, nostalgic video rental culture, and classic office comedy tropes, Undercover Miss Hong promises a fun yet clever look at identity, ambition, and unexpected connections. The teaser’s bold tone and confident humor suggest a drama that isn’t afraid to push boundaries while delivering binge-worthy entertainment. As anticipation builds, viewers are eager to see how this undercover mission unfolds and whether Geum-bo can keep her secret intact in a workplace full of surprises.
