Set in the 1990s, the office comedy "Undercover Miss Hong" revolves around Hong Geum Bo (Park Shin Hye) - an excellent female inspector at the Financial Supervisory Agency.
To carry out a secret mission, she infiltrates a securities company as a trainee Hong Jang Mi. In the process, she is drawn into a chaotic relationship with ambitious CEO Shin Jung Woo (Go Kyung Pyo) - also her ex-boyfriend.
The film has aired 4 episodes with the highest viewership rating of 7.4%. This achievement is quite good compared to competitors broadcasting in the same time slot, namely "The Matchmaker" (played by Ji Sung), "The Love Thief" (played by Nam Ji Hyun).
If in the first 2 episodes, "Investigator Hong" focused on introducing characters, along with the female lead's infiltration process with many "laughing and crying" situations, then in the recent 2 episodes, the work brings viewers many interesting slices revolving around the work and life of office workers in the 90s.
Initially, the film was involved in some controversy about Park Shin Hye's unusual appearance when she weighed down and cut her hair short to play a 20-year-old female student. However, in the last 2 episodes, the flexible improvisation of the actress in the image of Jang Mi gradually regained sympathy.
On the screen, the image of the talented, agile female lead having to hide her identity, working as a trainee doing odd jobs, and time after time finding ways to "avoid" her ex-lover was played gracefully by Park Shin Hye. The pairing between her and co-star Go Kyung Pyo was also praised for being harmonious.
13 years ago, the two collaborated in the movie "My Nam Nha Ben". According to Go Kyung Pyo, his co-star is a "model actor" - a friend he can learn a lot from, while Park Shin Hye praised him as a witty and interesting person.
Speaking more about her performance in "Investigator Hong", Park Shin Hye said that she once wondered if she would act too much in the movie "Judge of Hell" (a successful project before), but received a lot of sympathy, so with this project, she believes that if audiences can connect with the character Hong Geum Bo, they will like the movie.
