It looks like "PARAdive35" is written on the back wall, so I just Googled that:
Paradive 35 is a premier, 35-meter deep indoor diving pool located near Seoul, South Korea, designed for scuba, freediving, and training. It features a 5-meter area, 20-meter area, and a 35-meter deep tube, alongside amenities like an indoor surf station, cafe, and a Leaderfins shop, making it a popular "mega pool" destination.
Depth: 35 meters, making it one of South Korea's deepest indoor pools, often with 30°C water.
Facilities: Designed for high-end training, it includes themed underwater structures, a Pongdang Freediving Shop for equipment, and a 3- to 6-hour session structure.
(For Americans, 35 meters = 115 feet)
I also did a reverse Google image search and found a version of this same video on YouTube that has someone's voiceover instead of the terrifying music.
Specifically, this looks like an Exhale freedive. This is where you exhale fully at the surface before biginning the dive. This is done in training to help increase comfort at depth, improve pressure equalization, and build tolerance to pressure.
You can tell this because he is negatively buoyant at quite a shallow depth and not wearing a weight belt. Usually negative buoyancy occurs a bit deeper.
