Jung-woo Challenges Keum-bo in Undercover Miss Hong Episode 4
Undercover Miss Hong episode 4 opens with Keum-bo, disguised as Jang-mi, standing in front of President Jung-woo, the executives, and Hanmin’s directors during her disciplinary hearing. Deok-gyu tries to pin the blame on her. But Jung-woo interrupts and asks Gyeong-dong about the missing investor funds.
Gyeong-dong reveals that 3 billion won remains untraceable. Jung-woo challenges Keum-bo to redeem herself by locating the funds, despite Gyeong-dong insisting that even the national trade market would struggle to recover such an amount, making it nearly impossible for an intern to succeed.
Outside the meeting room, Albert, Jin-mok, and Yong-gi anxiously wait to check on Keum-bo. Jung-il attempts to mock her, but Albert steps in to defend her. Jung-woo calls Albert into the room and warns him that if Keum-bo fails to retrieve the missing funds, she will be fired.
Later, Jung-woo speaks with Bok-hee to learn more about Keum-bo (Jang-mi) and is left confused by the random details he discovers. Meanwhile, Keum-bo strategizes how to locate the funds while continuing her investigation into Yehppee’s identity.
At the same time, Chairman Kang berates Gyeong-dong for mishandling the trading deal with the company OneMillion. A flashback reveals that Kang himself orchestrated the insider trading scheme through Gyeong-dong, highlighting his manipulative control.
In the present, he scolds Gyeong-dong for failing to meet expectations. Meanwhile, Albert speaks with his father, seeking a way to help Keum-bo. Deok-gyu warns Albert that the market violation originated from Chairman Kang and urges him to comply with Kang’s decisions. Frustrated but determined, Albert struggles with the moral dilemma of supporting Keum-bo.

The next day, Keum-bo tracks the CEO to his hideout, using tips from local food takeout places to pinpoint his location. She discovers that the CEO, Kim Ki-soo, has already fled, but she finds shredded documents in the trash and collects them.
With the help of No-ra and Mi-sook, Keum-bo pieces together the shredded papers, which turn out to be Ki-soo’s flight tickets. No-ra informs Albert that Keum-bo is at the airport and will not be coming to work. Albert rushes there and helps her intercept Ki-soo.
