'Undercover Miss Hong' Ko Kyung-pyo and Cho Han-gyeol put the brakes on Park Shinhye's secret operation.
The new tvN Saturday-Sunday drama 'Undercover Miss Hong', directed by Park Sun-ho / written by Moon Hyun-kyung / planned by Studio Dragon / produced by Celltrion Entertainment, Studio Dragon, scheduled to premiere on Sat., Jan. 17, 2026, is a retro office comedy drama set at the end of the 1990s about 30-year-old elite securities regulator Hong Geum-bo (Park Shinhye) who disguises herself as a 20-year-old entry-level employee and goes undercover at a securities firm where suspicious flows of funds have been detected, leading to a series of chaotic events.
'Undercover Miss Hong' is generating anticipation as a meeting between the undisputed box-office queen Park Shinhye and tvN, while a host of strong actors including Ko Kyung-pyo, Ha Yoon-Kyung and Cho Han-gyeol join the cast to add synergy. Director Park Sun-ho, who directed 'Greasy Melo', 'Business Proposal' and 'Suspicious Partner', has joined the project, and together they plan to captivate home viewers with a turn-of-the-century office comedy drama.
The 'chaotic office poster' and teaser video released today (the 23rd) show Hong Geum-bo, who was forced to change her identity to a 20-year-old entry-level employee, and the tense encounters with the major obstacles who appear before her: Shin Jeong-woo (Ko Kyung-pyo) and Albet Oh (Cho Han-gyeol). Thirty-five-year-old securities regulator Hong Geum-bo goes undercover to obtain the secret slush fund accounting ledger of Hanmin Securities, hiding her identity and starting a covert infiltration operation, suggesting a rocky start to the story.
In particular, the 'chaotic office poster' teases the interconnected relationships of the three men and women who will become entangled at the same company, piquing viewers' interest. Behind Hong Geum-bo, who has completed a perfect visual transformation with a fresh bob and youthful styling, stand two men who will become major variables in her undercover mission. They are Shin Jeong-woo, the 'annoying ex-boyfriend' of Hong Geum-bo and the newly appointed CEO of Hanmin Securities, and Albet Oh, the 'lucky parachute' third-generation chaebol who entered the company following his grandfather's wishes; with their contrasting charms, they will create a chaotic, collision-filled relationship with Hong Geum-bo.
The teaser video released together fully reveals Hong Geum-bo's psyche as she shows a bleak expression, as if having hit a reef. Assigned a three-month mission period and infiltrating enemy lines, Hong Geum-bo reunites with Shin Jeong-woo, her ex-boyfriend from 15 years ago whom she once dated purely and who ended the relationship by calling her a 'cowardly XX', and she is desperate to hide her face. Adding to her predicament, Albet Oh, who left a first impression as a 'pervert' after an awkward argument at a video rental store, reappears as the parachute division chief and corners Hong Geum-bo. Curiosity grows about the direction of the turn-of-the-century office comedy that the three men and women, reconnected by unexpected ties, will portray.
Led by reliable actress Park Shinhye, the meeting of talented actors with distinct personalities and acting skills such as Ko Kyung-pyo, Ha Yoon-Kyung and Cho Han-gyeol can be seen in the new tvN Saturday-Sunday drama 'Undercover Miss Hong', which premieres at 9:10 p.m. on Sat., Jan. 17, 2026.
