Ha Yoon-kyung transforms into Go Bok-hee, a securities firm secretary who dreams daring dreams.
The new tvN Saturday-Sunday drama Undercover Miss Hong, directed by Park Sun-ho and written by Moon Hyun-kyung, scheduled to premiere Jan. 17, 2026, is a retro office comedy set in the late 1990s about 30-year-old elite securities regulator Hong Geum-bo (Park Shin-hye) who goes undercover as a 20-year-old junior employee at a securities firm where suspicious funds have been detected and the chaotic events that follow.
Ha Yoon-kyung plays Go Bok-hee, the president's personal secretary in the secretary's office at Hanmin Securities. Go Bok-hee is a uniquely charismatic figure who strides through the colorless Yeouido in a striking polka-dot dress, a lovable character with an irresistible charm and ambitious streak. Her plan to accumulate wealth and live freely as a "California girl" is disrupted when she meets her roommate Hong Jang-mi (Park Shin-hye).
The stills released today (the 16th) instantly convey the first impressions of Go Bok-hee, armed with a sharp charm. They capture her face as both the most senior secretary who handles tasks efficiently and the "queen sister" who commands her roommates, along with her flashy, vivid styling. Her transformation, perfectly recreating 1990s retro visuals and boasting perfect sync with the character, draws attention to Ha Yoon-kyung.
With Go Bok-hee and her roommates, each harboring their own secrets, living together under one roof, anticipation is focused on what will happen and on the special "womance" born from their fiery cohabitation.
Ha Yoon-kyung, who has left a strong impression on the public with her stable acting across a wide range of characters, will be the leader among the roommates, including Hong Geum-bo, who is disguised as a 20-year-old junior employee, and will create chemistry that swings between friendship and rivalry. The first broadcast of Undercover Miss Hong, which will deliver an unprecedented retro office comedy filled with a thrilling undercover operation, intense mind games and the cheerful exploits of the characters that fill the space between, is eagerly anticipated.
