Park Shin Hye and ITZY’s Yuna Team Up in Retro Comedy “Undercover Miss Hong” — Premiering January 17
Fans of K‑dramas are in for a treat as tvN’s upcoming drama “Undercover Miss Hong” brings together two powerhouse stars from different generations: Park Shin Hye and ITZY’s Yuna. Blending comedy, nostalgia, and sisterly chemistry, the series promises to deliver both laughs and heartfelt moments when it premieres on January 17 at 9:10 p.m. KST.
Set against the vibrant backdrop of the late 1990s, “Undercover Miss Hong” follows the story of Hong Geum Bo (Park Shin Hye), a sharp and disciplined financial supervisory officer in her 30s. When suspicious financial transactions are detected at a securities firm, Geum Bo is assigned an unusual mission: she must go undercover as a 20‑year‑old rookie employee to expose the truth.
But pulling off such a transformation is no easy task. Enter her younger sister, Hong Jang Mi (Yuna), a trendy and free‑spirited youth who perfectly embodies the Gen X vibe of the 1990s. With her bold fashion sense, carefree attitude, and natural flair for style, Jang Mi is the complete opposite of her polished and restrained older sister. Yet it’s precisely this contrast that makes their dynamic so entertaining.
To infiltrate Hanmin Securities, Geum Bo must borrow Jang Mi’s identity and learn to blend in with the younger crowd. Beyond changing her appearance, she must also master the subtle nuances of youth culture—everything from slang and fashion trends to the carefree energy of twenty‑somethings. When Geum Bo struggles to convincingly pass as a 20‑year‑old, Jang Mi steps in with fashion makeovers, styling hacks, and playful coaching sessions on “how to look young.”
Despite their 15‑year age gap, the sisters share a realistic bond filled with bickering, laughter, and heartfelt support. Their chemistry is expected to be one of the drama’s biggest highlights, offering audiences both comedic relief and touching family moments.
With Park Shin Hye’s return to the small screen and Yuna’s fresh idol‑turned‑actress energy, “Undercover Miss Hong” is shaping up to be one of tvN’s most anticipated premieres of 2026. The retro setting, undercover antics, and sisterly teamwork promise a drama that balances nostalgia with modern humor—making it a must‑watch for fans of both stars.
