Shadow Trek

“The path you take is the right answer, and I will make it the right answer. Go forward.”
The main character, Sarah, who cannot receive light, loses her memory for unknown reasons and wakes up on a cliff.
The only memory that Sarah has left is that she was picking up stars.
If Sera does not receive light, she is eroded by darkness. And the shadow, an unknown entity that helps to avoid being eroded.
He doesn't know, but he helps me and tells me to go forward. Can I believe in its existence?
Is it right to move forward?
