Satoru has never been a sentimental man. He has never held a love for the various homes he's lived in. There's no nostalgic feeling for a long passed childhood spent in the dying sunset's light on a muggy summer evening. There's no want for forgotten friends and teachers. Yet, something continues to yank him backwards. There is a void in his heart, it aches and yearns for something that he finds himself often out of breath. No matter how many times he asks himself 'What am I missing?' he never has an answer.
