Netflix has released the first electrifying trailer for Undercover Miss Hong, showcasing Park Shin-hye in a bold dual performance that fuses sharp financial intrigue with sharp-witted comedy.
The trailer plunges viewers into the late 1990s world of Hanmin Securities, a firm shadowed by shady dealings. Park Shin-hye plays Hong Geum-bo, a no-nonsense elite supervisor at the Financial Supervisory Service, who goes undercover as the seemingly naive 20-year-old Hong Jang-mi to infiltrate the company as a rookie employee. The footage captures her clever shift between razor-sharp sleuthing and the comedic chaos of office life. Tensions escalate with the arrival of Sin Jeong-woo, portrayed by Go Kyung-pyo, the ruthless, profit-obsessed new CEO and corporate raider. Their encounters spark unexpected chemistry, teasing a complicated past that promises both romantic sparks and high-stakes conflict.
The series boasts an impressive supporting cast. Ha Yoon-kyung plays Ko Bok-hui, a resident of a single women's dormitory caught up in the unfolding drama. Cho Han-gyeol appears as Albert O from the Financial Supervisory Service, while seasoned actors Lee Deok-hwa and Choi Won-young portray the influential Kang family patriarch and president behind Hanmin Securities. Adding fresh energy, ITZY's Shin Yu-na makes her acting debut as Hong Geum-bo's younger sister, who coincidentally shares the same name as the undercover alias. The ensemble is rounded out by Kim Hyung-mook as managing director O Deok-gyu, Kang Chae-young as teller Kim Mi-suk, and a lively group of department heads and staff who bring the bustling 1990s office to life.
Undercover Miss Hong delivers a genre-blending mix of black comedy, undercover investigation, and romantic tension, all set against Korea's turbulent 1990s finance scene. The 16-episode series, directed by Park Seon-ho and written by Moon Hyun-kyung, will premiere on tvN on Saturdays and Sundays at 9:20 p.m. KST, with simultaneous global streaming on Netflix beginning January 17, 2026. Each episode runs approximately 70 minutes and carries a 15+ rating, making it an ideal weekend watch for fans of clever, character-driven stories.
Park Shin-hye, beloved for her compelling turns in The Heirs, Pinocchio, and Doctor Slump, steps back into the spotlight after a short break, taking on one of her most layered roles to date. Go Kyung-pyo, recognized from Reply 1988 and Private Lives, matches her intensity as the enigmatic and ambitious CEO. Originally developed under the working title Miss Undercover Boss, the drama leans heavily into nostalgic period details—from vintage office equipment to era-specific fashion—to immerse viewers in its retro atmosphere.
Shortly after the trailer launch, Netflix Korea unveiled a compelling new poster via their official X account. The image prominently features Park Shin-hye in a dimly lit office, seated confidently amid glowing stock market screens, holding a newspaper that announces a major corporate scandal. The design perfectly encapsulates her character's poised yet secretive nature, heightening excitement for the upcoming release.
With its distinctive premise, powerhouse cast, and Netflix's global reach, Undercover Miss Hong is positioned to be one of the most anticipated K-dramas of early 2026.
