Anticipation is building for the upcoming fourth episode of tvN’s “Undercover Miss Hong,” as the drama continues to blend suspense with lighthearted comedy. Set in the late 1990s, the series stars Park Shin Hye as Hong Geum Bo, a seasoned financial supervisory officer in her 30s who goes undercover as a 20-something rookie employee at a securities firm flagged for suspicious transactions.

In the previous episode, Hong Geum Bo’s carefully planned mission took an unexpected turn. After stepping in to prevent a trading error that could have resulted in massive losses, she found herself summoned to a disciplinary hearing. The situation became even more precarious when her ex-boyfriend, Shin Jung Woo (played by Ko Kyung Pyo), appeared at the hearing, putting her true identity in serious jeopardy.
Newly released stills from episode four reveal Hong Geum Bo pushing herself to the limit in order to uncover the identity of the elusive whistleblower known as “Yeppi.” Determined and fearless, she is seen sprinting through an airport in a tense chase sequence, while Albert Oh (Cho Han Gyul) attempts to stop her, his anxious expression hinting at the risks ahead.
Beyond the suspense, the next episode will also highlight the growing bond among the four roommates of Room 301, offering moments of warmth and camaraderie amid the pressure. At the same time, Hong Geum Bo’s nerve-racking encounters with Shin Jung Woo continue, as she struggles to avoid him while keeping her cover intact.
With secrets hanging by a thread and the mystery of “Yeppi” still unresolved, viewers are left wondering how far Hong Geum Bo will go to complete her mission. The next episode of “Undercover Miss Hong” airs on January 25 at 9:10 p.m. KST.
