Suguru lived in an ordinary family with one child (Suguru). He had a dog that had been with him since he was five years old, and he called the dog Jack. A big, black and playful Labrador. The Geto family's house was the most ordinary, with a delicate pink coating on Sranjose Street, and next to it was a cottage that belonged to the Gojo family. Suguru's parents and the boy next door, Satoru, had been friends for many years. When the boys grew up, they also began to actively communicate, but they had known each other since birth.

Many years have passed, the year was 2003, Suguru is already 17 years old, Satoru will soon turn 17 years old too. Suguru went out into the courtyard in his slippers, shouting to his mother that he was going to get sick, as he was going to visit Satoru.
