Park Shin Hye, Go Kyung Pyo, Ha Yun Kyung, and Cho Han Gyul have confirmed their casting in tvN’s upcoming retro office comedy Miss Undercover Boss (working title). It is set to premiere in the first half of 2026.
Earlier this year, it was reported by Korean media outlets that Park Shin Hye and Go Kyung Pyo were approached to lead the new retro office comedy.
On July 1, tvN confirmed the cast for their new show as well as revealed broadcast plans.
‘Miss Undercover Boss’ – Retro Office Comedy with an Undercover Twist
‘Miss Undercover Boss’ is a refreshing throwback set in the late 1990s Yeouido financial district. The drama tells the story of a 30-year-old elite supervisor at the Financial Supervisory Service who goes undercover as a 20-year-old rookie high school graduate at a securities firm. It is a company where suspicious fund flows have been detected.
Park Shin Hye as an Elite Inspector Turned Rookie
Park Shin Hye plays Hong Sam Mo, an elite Financial Supervisory Service supervisor who goes undercover overnight as a rookie high school graduate employee at Hanmin Securities.
Audiences can look forward to seeing Park switch between a sharp, by-the-book career woman and an awkward newcomer thrown into a shady corporate world. Following her transformation in The Judge from Hell, fans are looking forward to seeing Park’s comedic timing and new side in this dramatic role reversal.
Park Shin Hye has delivered standout performances in The Heirs, Pinocchio, Doctor Slump, and Memories of the Alhambra.
Go Kyung Pyo as a Cold-Blooded CEO
Go Kyung Pyo stars as Shin Jung Woo, the new CEO of Hanmin Securities. He is a born management consultant and notorious corporate raider who trusts only numbers and never hesitates to achieve his goals — no matter the means.
When he crosses paths with undercover Hong Sam Mo, who looks just like Hong Jang Mi, a woman he once loved.
Go Kyung Pyo is known for his memorable performances in Love in Contract, Reply 1988, Frankly Speaking, and more.
Ha Yun Kyung and Cho Han Gyul Join the Ensemble
Ha Yun Kyung (Resident Playbook, Gangnam B-Side, Flex x Cop) plays Go Bok Hee, the stylish secretary to Hanmin Securities’ president. She is the unofficial boss of the dorm room where undercover Park Shin Hye lives. As a sassy ‘tsundere’ character who thrives in the cutthroat Yeouido scene, Ha Yun Kyung brings energy to the retro setting.
Cho Han Gyul (The Haunted Palace, Jinxed At First) appears as Albert Oh, the carefree grandson of Hanmin Securities’ chairman. Dropped into the company on a golden parachute, this cinephile has no interest in the corporate world until he encounters the mysterious rookie played by Park Shin Hye.
Production Team
Miss Undercover Boss is helmed by director Park Sun Ho, known for hits like Suspicious Partner, Business Proposal, Brewing Love. The script comes from writer Moon Hyung Kung, who wrote Into the Ring.
The production team shared their excitement, saying:
We’re very pleased to be working with trusted actors Park Shin Hye, Ko Kyung Pyo, Ha Yun Kyung, and Cho Han Gyul. Please look forward to ‘Miss Undercover Boss’, which will sneak into viewers’ hearts with a lighthearted and exciting story at the point where the end of the century and today’s reality meet.
Fans can expect a perfect mix of undercover secrets, office politics, retro nostalgia, and witty humor when Miss Undercover Boss premieres on tvN in 2026.
