The upcoming mystery and comedy film "The Noisy Mansion" aims to explore how severe inter-floor noise can devastate one's life, based on the director Lee Ru-da's personal struggles with the issue.

"I experienced extreme inter-floor noise and I realized how much quality of life improves when that noise is gone," Lee said during a press conference at a theater in Seoul, Monday.

“By centering the story around a busybody who is fixated on even the smallest things around her and using the common theme of inter-floor noise (that many Koreans experience), I thought I could create a story that could resonate with many people."

"The Noisy Mansion" follows Geo-wool (Gyeong Su-jin), a jobless busybody who roams the neighborhood playing detective. To uncover the source of inter-floor noise that echoes through her apartment every morning at 4 a.m., she investigates her neighbors.

Set in the everyday space of an apartment building, the film features Ko Kyu-pil, Kim Joo-ryeong and Choi Yoo-jung as residents, turning the mundane into the mystifying.

The director, making her directorial debut with this film, added that she wanted to explore the positive influence a snoop could have.

"I wanted to convey a warm message of quelling things that disturb our quality of life and inspiring and connecting with those around us," she said.

Lead actor Gyeong explained that the film's protagonist, Geo-wool, is not much different from her real self.

"When I worked part-time in the past, the boss didn't pay me for several months. I remember waiting in front of the door with my colleagues for a month to get our money. I think I'm similar to Geo-wool in that I can't stand injustice," she said.

Given that apartments are the most common type of residence in Korea, with about 53 percent living there, the film is expected to be highly relatable to many.

The mystery escalates due to the noise common in old apartment complexes and the desire to demolish and redevelop the residence for profit. However, director Lee balances the tension with humor.

"Regarding inter-floor noise, I understand that horror and thriller genres might seem suitable, but I personally like lighthearted and fun mystery stories, so I set the genre as a cheerful mystery-chase,” the director said.

“The Noisy Mansion” will hit theaters on Wednesday.
