Undercover Miss Hong | Official Trailer | Netflix — Workplace Comedy, Corporate Crime, and Ex-Lovers Collide

Going undercover is hard.

Going undercover as your 20-year-old self while investigating corruption—and running into your ex who’s now the CEO—is chaos on another level.

That’s the irresistible hook behind Undercover Miss Hong, Netflix’s upcoming Korean workplace comedy series arriving January 17, 2026, exclusively on Netflix.

Set in 1997 Seoul, the Official Trailer promises a sharp blend of corporate intrigue, romantic tension, and fish-out-of-water comedy—anchored by a charismatic lead performance from Park Shin-hye.

What Is Undercover Miss Hong About?

At the center of the story is Hong Keum-bo, a 35-year-old elite inspector at Korea’s Financial Supervisory Service. She’s brilliant, feared in Yeouido’s financial district, and known by her nickname: the Witch of Yeouido.

Her new assignment? Go undercover inside Hanmin Investment & Securities, a firm suspected of serious financial wrongdoing.

The twist:

• Keum-bo looks young enough to pass as a 20-year-old junior employee

• She must survive entry-level office life while secretly investigating corruption

• The company’s new CEO turns out to be her former lover

From that moment, her mission becomes far more complicated than planned.

Official Trailer Breakdown: Comedy With Bite

The Undercover Miss Hong Official Trailer leans heavily into contrast—and that’s where the humor shines.

You see:

• A confident, feared inspector suddenly fumbling as an intern

• Corporate chaos disguised as office etiquette

• Nostalgic 1990s Seoul aesthetics

• Sharp verbal sparring loaded with unresolved romantic tension

The trailer balances slapstick moments with genuine stakes. Yes, it’s funny—but there’s real danger beneath the humor, especially as Keum-bo navigates power-hungry executives, hidden agendas, and a company built on secrets.

Park Shin-hye in a Career-Refreshing Role

This might be one of Park Shin-hye’s most playful roles yet.

As Hong Keum-bo, she switches effortlessly between:

• Ruthless financial investigator

• Awkward junior employee

• Emotionally guarded ex-lover

It’s a role that demands comic timing, authority, and vulnerability—and the trailer suggests she nails all three.

Opposite her is Go Kyung-pyo as Shin Jeong-woo, the newly appointed CEO of Hanmin Securities. Cold, ambitious, and emotionally closed off, he’s everything corporate—and everything unresolved from Keum-bo’s past.

Their chemistry fuels both the romance and the tension.

Supporting Cast That Elevates the Workplace Chaos

The series surrounds its leads with a strong ensemble:

• Ha Yoon-kyung as Ko Bok-hui, a sharp survivor navigating corporate life with her own exit plan

• Cho Han-gyeol as Albert Oh, a conspiracy-loving crisis manager

• Veteran actors like Seo Hyun-chul, Kim Won-hae, and Lee Deok-hwa add political weight and generational power struggles

Every character represents a different face of corporate ambition—making the comedy sharper and the stakes higher.

More Than Comedy: Corporate Power and Identity

While Undercover Miss Hong plays for laughs, it’s grounded in serious themes:

• Financial corruption

• Corporate optics vs truth

• Gender and age bias in the workplace

• Identity as both performance and survival

Keum-bo’s undercover role becomes a commentary on how power shifts depending on who people think you are.

The show doesn’t just ask who’s corrupt—it asks who gets believed.

Creators & Production Confidence

The series is created by Park Seon-ho, Moon Hyun-kyung, and Na Ji-hyun, with direction by Park Seon-ho—known for blending humor with emotional clarity.

Already scheduled for a prime weekend slot in Korea, the Netflix release positions Undercover Miss Hong as a global-friendly K-drama that doesn’t rely on melodrama alone.
