tvN’s Undercover Miss Hong brings a refreshing retro vibe to the K-drama lineup with a story full of disguise, comedy, and unexpected romance. Set in the late 1990s, the drama combines workplace humor with an undercover mission that turns daily office life upside down.
The plot follows an elite securities inspector in her mid-thirties who is sent on a covert mission to infiltrate a suspicious financial company. Thanks to her youthful appearance, she goes undercover as a 20-year-old rookie employee. Balancing her real identity with her fake one proves harder than expected, especially as she navigates office politics, friendships, and growing romantic tension.
Park Shin-hye leads the series as the sharp and determined undercover agent, while Go Kyung-pyo stars as a cool-headed corporate figure whose path becomes closely intertwined with hers. Cho Han-gyeol’s character, a free-spirited chaebol heir, adds charm and unpredictability to the story.
With its nostalgic setting, comedic misunderstandings, and slow-burn romance, Undercover Miss Hong is set to premiere on January 17, 2026, at 9:10 PM on tvN.
