A powerhouse cast is ready to transport viewers to the vibrant, chaotic world of late-’90s Yeouido in Miss Undercover Boss—tvN’s new retro office comedy slated to premiere in early 2026.
With Park Shin Hye, Go Kyung Pyo, Ha Yoon Kyung, and Cho Han Gyeol officially confirmed, this drama is already turning heads before cameras roll.
A Hilarious Double Life in Yeouido
Miss Undercover Boss (working title) follows Hong Geum-bo, a no-nonsense, career-first supervisor at the Korea Financial Services Commission who unexpectedly finds herself undercover as a 20-something rookie at a suspicious securities firm. The twist? She’s gone from high-ranking official to newbie employee—complete with a fake identity and a high school diploma. What unfolds is a rollercoaster of office antics, hidden agendas, and identity chaos—all set against the energetic backdrop of Korea’s financial epicenter in the late ’90s.
Taking on the dual role, Park Shin Hye will showcase both the sharp edge of an elite professional and the awkward charm of a clueless entry-level worker. After impressing viewers with her powerful transformation in The Judge from Hell, Park is expected to deliver a refreshing, comedic performance that may just redefine her career.
Enter the Cool-Headed CEO and the Office Oddballs
Go Kyung Pyo plays Shin Jung-woo, the icy new CEO of Hanmin Securities, a no-nonsense corporate raider with an obsession for numbers and a talent for turning companies around—by any means necessary. Things get complicated when he encounters Park Shin-hye’s undercover character, whose face reminds him of a woman he once loved. Known for his standout roles in Frankly Speaking and Love in Contract, Go is poised to bring an emotionally layered performance to this romantic and corporate chess match.
Adding to the ensemble is Ha Yoon Kyung as Ko Bok-hee, a bold and stylish secretary with a street-smart survival strategy and a tsundere charm. She doubles as the big sister figure in the dorm room where Park’s character lives under her fake identity. With a resume full of complex roles in dramas like Extraordinary Attorney Woo and See You in My 19th Life, Ha promises to bring both flair and heart to the screen.
Rising star Cho Han Gyeol joins as Albert Oh, the quirky, cinephile grandson of the Hanmin Securities chairman. With no interest in business but plenty of flair for disruption, Albert’s character adds a fresh dose of unpredictability, especially when he finds himself unexpectedly drawn to the undercover rookie shaking up his world. After gaining attention in The Haunted Palace, Jo is set to win more fans with his bubbly energy.
Retro Meets Relatable
With a stellar cast and a production team led by director Park Seon-ho (Suspicious Partner, Wok of Love) and writer Moon Hyun-kyung (Into the Ring), Miss Undercover Boss aims to blend nostalgic retro comedy with today’s workplace realities. The series promises both laughter and heart as it explores what it means to navigate ambition, identity, and connection in a rapidly changing world.
The production team shared, “We’re thrilled to be working with such a talented and trusted cast. Miss Undercover Boss will strike a chord with viewers by combining the excitement of the century’s end with a bright, modern-day sensibility.”
Get ready for office politics, undercover chaos, and some serious late-’90s nostalgia. Miss Undercover Boss is expected to premiere in the first half of 2026—and if this cast is any indication, it’s already a must-watch.
