Plot overview[]

Early life[]

John was formerly owned Masayoshi’s son, Masato, whom he loved very much. Because Masato’s mother didn’t want John to enter her son’s room, John had to sleep outside. Because of his never ending love for his master, John always slept outside of Masato’s room, waiting for his owner to come out and greet him every morning. After Masato’s death, John was greatly saddened from this, but he never stopped waiting in front of his late owner’s former bedroom door, keeping on the hope that the boy would come out and greet like old times.
