As we step into 2026, K-drama fans have a fresh treat lined up: "Undercover Miss Hong," a witty blend of comedy and crime set against the bustling financial district of late-1990s Yeouido. Premiering on January 17, this 16-episode series promises laughs, intrigue, and a nostalgic nod to an era when women in the workplace were still breaking glass ceilings – one disguise at a time. Directed by Park Sun-ho and written by Moon Hyun-kyung, it captures the chaos of corporate life with sharp humor and heartfelt moments.

Overview

"Undercover Miss Hong" (Korean: 언더커버 미쓰홍) unfolds in 1997, a time when the term "Miss" was the default for female employees, underscoring the era's gender dynamics. This workplace drama follows an elite financial investigator who sheds her power suit for a schoolgirl uniform to infiltrate a shady securities firm. Airing Saturdays and Sundays on tvN from January 17 to March 8, each episode clocks in at around 70 minutes, making it a perfect weekend binge. Tagged with elements like undercover operations, double identities, and black comedy, it's rated 15+ for its clever mix of financial sleuthing and romantic entanglements. Produced in South Korea, the series dives into the finance industry's high-stakes world while delivering feel-good escapism.

Plot Synopsis

At the heart of "Undercover Miss Hong" is Hong Geum-bo (Park Shin-hye), a no-nonsense 30-something elite supervisor at the Financial Supervisory Service – nicknamed the "Yeouido Witch" for her razor-sharp skills. When suspicious fund flows surface at Hanmin Securities, she goes incognito as 20-year-old high school grad Hong Jang-mi, complete with a youthful bob haircut and rookie enthusiasm. Posing as a low-profile teller, Geum-bo navigates office politics, dorm life, and unexpected reunions while hunting for a hidden slush fund ledger.

Complications arise when her ex-lover, Shin Jeong-u (Go Kyung-pyo), steps in as the firm's new CEO – a ruthless corporate raider who spots her familiar face and stirs up old flames. Add in a quirky roommate crew and a charming chaebol heir with movie-mania, and Geum-bo's mission spirals into a web of misunderstandings, close calls, and budding alliances. Will she expose the corruption without blowing her cover? The story balances tense investigations with laugh-out-loud mishaps, all wrapped in a love triangle that questions if numbers – or hearts – tell the real truth.

Fun Facts & Highlights

Awkward First Encounters

In one hilarious teaser, Park Shin-hye's Geum-bo tries renting a 19+ video to prove her "youth," only to butt heads with Cho Han-gyeol's Albert Oh over the last copy – leading her to dub him a "pervert" in their disastrous meet-cute.

Dorm Shenanigans

Room 301 steals scenes with its quirky quartet. Ha Yun-kyung's Bok-hee grills the "baby-faced" Jang-mi on her suspiciously mature vibe, sparking group giggles, while the roommates bond over cookies, magazines, and midnight chats that nearly derail the mission.

Ex-Lover Tension

Go Kyung-pyo's piercing stare-down with Park Shin-hye in the office hallway screams unresolved history, as he questions her "rookie" glow-up from 15 years prior.

Cinephile Dreams

Cho Han-gyeol drew from 1990s films for Albert's carefree heir vibe, blending open-collar rebellion with suited-up poise – complete with bold lines like, "It's okay to two-time."

Script Reading Sparks

The table read buzzed with energy, where Park Shin-hye nailed her dual personas, and the group improvised laughs that foreshadowed the on-screen sisterhood.

Era Easter Eggs

Expect nods to '90s tech woes, like frantic pager checks during stakeouts, and Geum-bo's bold quips like "Work is done on competence," flipping patriarchal norms.
