Su Wan, a social animal, unexpectedly awakens as an NPC in the horror infinite streaming game "Midnight Playground". She must balance "playing a horror role" and "preserving self-awareness" to survive. However, she develops a "spiritual connection" with Xie Mingyan, the ultimate boss who is cursed by the system. The two go from "utilizing symbiosis" to "two-way protection", and finally join forces to break the shackles of the system and achieve freedom in a taboo symbiosis story.
