According to Nielsen Korea, episode 6 of "Filing for love" (Secret Inspector) broadcast on May 10 reached a viewership rating of 9.4%, nearly double that of the previous episode (5.9%). Not only topping the broadcast time slot on all channels, this is also the most watched program on cable television in Korea during the day.
In the new developments, the relationship between Joo In Ah (Shin Hye Sun) and Noh Ki Joon (Gong Myung) continues to change after both gradually become more open about emotions. After learning about In Ah's past, Ki Joon chooses to be by her side to comfort her. However, In Ah quickly falls into a state of confusion when she discovers that he is living in the same house with secretary Park Ah Jeong (Hong Hwa Yeon).
However, instead of developing in the familiar misunderstanding direction, this detail drags both into the process of investigating the truth behind the incident related to PK - the image model of Haemu Group. The tension of the episode is pushed to a higher level when Jeon Jae Yeol's wife (Kim Jae Wook) suddenly appears at the board meeting.
Notably, PK is revealed to be the secret lover of this vice president. Amidst the chaotic situation, Ki Joon publicly defends In Ah, and at the same time decides to express his feelings without hiding anything. At the end of the episode, the relationship between In Ah and the Vice President reveals many suspicious signs, making Ki Joon unable to hide his tension. This is said to become an important bottleneck in the next stage of the film.
Previously, the kissing scene between In Ah and Ki Joon in episode 4 once created an effect on social networks, contributing to helping "Secret Detective" achieve a rating of 7.9% and maintain its appeal in later episodes.
Korean media assessed that the strength of the work lies in the combination of office, investigative and romantic comedy elements with a fast pace of storytelling, continuously creating new situations. The harmonious acting and natural "chemistry" of Shin Hye Sun and Gong Myung are also considered factors that help the film increase discussion.
Sharing about the project, Gong Myung said that he was attracted by the context of auditing wrongdoing in the office - a factor that creates a different color for the film compared to ordinary office romantic comedy works. "I have prepared very carefully to show Noh Ki Joon's charisma, from his dressing style, tone to facial expressions.
Meanwhile, Shin Hye Sun said that she decided to participate in the film because she wanted to bring the audience a work that can be watched comfortably but still has enough depth. According to her, "Secret Inspector" not only exploits romantic elements but also reflects many hidden faces in the working environment in a way that is both witty and realistic.
