Okay, so, this morning I remembered this vocaloid song that I used to listen to all the time, but I have no idea what's its name or what it is about. I do remember the music video though: it was done in MMD and there was an older Miku standing in front of some rails, waiting for the train, when she sees a younger version of herself on the other side; the video ends with the train passing and the kid-miku disappearing. Do you have any ideas of what it could be??
