19th Floor Season 1

Unconscious after a car accident, university student Chun Yu and her best friend Qing You mysteriously find themselves inside the dangerous world of a VR game. Several other people have also unwittingly ended up here, and they soon discover they were all involved in the accident - except for substitute teacher Gao Xuan, who claims to have simply fallen asleep. Seeing no other option than to play the game, they eventually beat the level and wake up ... only to immediately return the next night.
