A shocking clash between maternal love and paternal duty in tvN's new drama 'Undercover Ms. Hong' is already grabbing attention.
The related teaser was uploaded on March 18, 2026, to the tvN DRAMA YouTube channel.
In the footage, the protagonist Hong Geum-bo (played by Park Shin-hye) is an elite securities regulator in the 1990s who goes undercover as a rookie hire at a brokerage firm to investigate suspicious money flows.
One standout line steals the show: "A mother's responsibility and a father's duty—where is the line?"
Blending a distinct retro vibe with amped-up comedy, the series aims to set itself apart from typical office dramas. The on-screen chemistry between Park Shin-hye and Go Kyung-pyo is building hype, and behind-the-scenes stories from the shoot are drawing major interest.
