Bai Yu is an ordinary office worker. When he wakes up one day, he suddenly finds that he can travel into different film and television drama worlds. Each world is a popular domestic drama in 2025, ranging from fairy tales to period dramas. She is not the protagonist, nor is she a supporting role, she is just a passerby who has no lines. For example, the figure standing in the crowd watching the duel in "Tenchi Kenshin", or the neighbor passing by while shopping for groceries in "Alley House". But she discovered that even just passing by, a look or a hand outstretched could quietly change the direction of the plot. The system does not give cheats or task rewards, so she can only live stably on her own. These worlds are frighteningly real, with rivers and lakes and markets, intrigues and fireworks, and she has to avoid the center of the storm without being noticed, without being completely numb and watching. Slowly she realized that the so-called "passerby" was actually the freest eye in the world.
