The protagonist says goodbye to her night classroom and the shopping mall in this song. She feels like she has lost her voice and her shadow here. She wants to go somewhere else where no one knows her and start over with a new name. She is on a night train and sees her memories drifting away on the other side of the window. She wonders if this is for the best. She wants her partner, who is far away, to notice her and understand her. She wants to be forgiven. She feels like she has nothing to lose. She says goodbye to the red street lights and wonders where she lost her heart. She doesn't want to be alone anymore. She is waiting for someone better than her partner. She wants to go somewhere where she doesn't need anything. She wonders if the night train, which carries only sadness, will take her there. She wants to be forgiven because she is now full of anxiety. She wants her partner to notice her and understand her. She feels like she has nothing to lose. She says goodbye to somewhere and wants to go somewhere where no one knows her. She wants a faint light. She wonders if the night train, which carries even the tears on her cheeks, will take her there. She wants her partner, who is far away, to notice her and understand her. She wants to be forgiven. She feels like she has nothing to lose.
