The heroine Wen Yuxi met a strange cat after school, and then accidentally entered a strange bus and came to a world. This seemed to be the earth 30 years ago. The heroine desperately collected crystal cores to go home, but after collecting the crystal cores of this world, she made a wish to go home. She thought that when she got on the bus, the bus would take her back to the earth. She seemed to have really returned to the earth, but was this actually the case?
…
She came to the next platform and collected crystal nuclei in different platforms. She also met her different partners, but in the process, she also discovered something was wrong.
At the last stop, she returned to Earth, but the sky had already changed.
After collecting the crystal cores, she made a wish to the gods, hoping that the world would return to normal.
So the 438th "cycle" begins.
She got on a bus by mistake again after school. Everything seems to be similar to the last "loop", but one person is missing...
Purpose: In the face of crisis of responsibility, should you care for the small family or everyone?
