The series is the result of a collaboration between screenwriter Son Ho-young, winner of the Excellence Award in the Series category at the JTBC New Writers Playwriting Contest in 2021, and director Mo Wan-il, known for Misty (2018) and The World of the Married (2020).

The English title of the production was changed from the working title 'Alone in the Woods' to 'The Frog'.

Kim Yoon-seok, Yoon Kye-sang and Go Min-si were cast in the series in 2022, while Lee Jung-eun, Park Ji-hwan and Ha Yoon-kyung joined the cast in 2023.

On February 20, 2023, it was officially confirmed that Kim Yoon-seok, Yoon Kye-sang, Go Min-si and Lee Jung-eun would be the protagonists of the series, while singer and actor Chanyeol was confirmed to the cast by February 2024.

Yoon Kye-sang, Park Ji-hwan and Hong Ki-joon reunited to work together in this series three years after the film Sinkhole (2021).

The work won the Excellence Award in the Series category of the JTBC's new writers screenplay competition in 2021, before being adapted for the screen.

On the review aggregator Rotten Tomatoes, the series received 56% approval based on 9 critic reviews, with an average score of 5.7/10.

Critic David Tizzard from The Korea Times stated that the series attempted to emulate works such as The Shining and Parasite, but ended up sounding like 'Disney-level morality dressed in a miniskirt trying to be sexy for Netflix', with a Tarantino-style soundtrack without the screenwriter's dialogue, humor or tension; he also noted similarities between the plot and the real-life case of Koh Yuh-jeong in South Korea.
