Bangtalchul

Overly rational. Sociopathic, even. Sean's unfeeling personality consistently drives people away from him. That is, until he wakes up after a night of heavy drinking in... an escape room? Now he must use his unique mind and join hands with other players to survive sadistic games of life and death. The only way out is to escape!
