K-pop group ZEROBASEONE will appear on Mnet Plus original variety show 'Breath Quiz Season 2' Episode 3, participating in a survival game at an abandoned research facility. Airing on the 28th at 6 PM, the episode is based on a creepy urban legend about a sleep research center that creates 'eternally sleepless life forms.' The mysterious 'Experimental Subject No. 13,' the sole survivor of a special drug experiment, serves as the seeker. ZEROBASEONE must escape the research facility within 4444 seconds while avoiding Subject 13, who is extremely sensitive to sound. During preview footage, when storyteller Lee Jung-hyun pointed out member Sung Han-bin's heavy breathing, Han-bin visibly froze in tension. Returning to Season 2 after appearing in Season 1's water park episode, the group faces a completely transformed atmosphere and setting. The episode will also broadcast on Mnet at 11 PM on the 29th.
