Very non-intentional cinematography. Only to light the picture well, not to convey any emotion. The movie about digging pipes underground should at least be a little bit claustrophobic, isn't it? Have you even heard the word "camera lens"?

And what mobile provider is so generous to put their phone lines in sewers underground?

It's not the best movie, but it's weird lively energy I enjoyed. It was especially fun to see Lee Soo Hyeok and Seo In Guk in something more dynamic and different. I feel they had fun filming this project.
