Gu Pan, 28 years old, advertising planner, a screw in the urban steel forest. Repeating it day after day, she almost forgot the color of her dreams. Until one rainy night, when she stepped on the legendary last subway train, she discovered that there was a mysterious door with a shimmering light at the end of the car!
This door is the only entrance to the "Parallel World Fragments"! Behind the door, the world is full of strange things: there are painters who are shrouded in gray all day long, travelers who are lost in the flow of time, and singers whose songs have been forgotten... They are all trapped in their "fragments", waiting for a glimmer of life.
From a bystander, Gu Pan is gradually involved in the fate of these broken worlds. She uses her wisdom and empathy to help them regain their colors, memories and songs. Every time she takes action, it not only lights up the world of others, but also rekindles the long-extinguished dream spark deep in her heart.
However, these "fragments" are not a place of peace. An all-devouring "nihility crisis" is quietly spreading, not only threatening the parallel world, but even beginning to erode the reality where Gu Pan lives! Under the secret guidance of the mysterious subway driver Lao Yang, Gu Pan realized that she was no longer the ordinary social animal. She must unite those "partners from other worlds" who have been helped by her, gather their faith and strength, and jointly resist this cross-dimensional catastrophe. Can an ordinary person's adventure reverse the fate of the world and protect her and her friends' home? This is an epic adventure about courage, wisdom and protection. She will be the only hope!
