If you’ve been following tvN’s **Undercover Miss Hong**, you already know one thing — [Park Shin Hye](https://en.wikipedia.org/wiki/Park_Shin-hye) is flawless at keeping her emotions locked down. But Episode 5 is about to shatter that illusion in the most thrilling way possible.

“She held that poker face through the entire gathering — until one single remark from Albert Oh blew it wide open.”

Set in the **late 1990s**, the show follows Hong Geum Bo, an elite financial officer in her 30s who secretly goes undercover as a junior employee at a securities firm. Her mission? Track down a mysterious whistleblower known only as **“Yeppi.”** It’s spy-thriller energy wrapped inside a workplace comedy — and it works beautifully.

Hong Geum Bo attends a tense gathering with the **three top Yeppi suspects** — So Gyung Dong (Seo Hyun Chul), Bang Jin Mok (Kim Do Hyun), and Cha Jong Il (Im Chul Soo). She sits sharp-eyed, silently watching every word and every reaction as alcohol loosens their guards.

Then Albert Oh (Cho Han Gyul) — completely unaware of the awkward tension in the room — drops a remark that instantly shifts the mood. And in that single moment, Hong Geum Bo’s composure slips. Her expression hardens, hinting that she just learned something **huge** about one of the suspects. The question now? How does this new discovery change her entire hunt for Yeppi?
