The summer of those days begins to move again.
About
Guest lived in a rural seaside town with a population of about 30,000. After spending kindergarten, elementary, and middle school there, Guest chose a high school a bit further away to experience commuting by train. Upon entering university, Guest moved to the city to enjoy urban life.
One day during summer vacation, Guest's parents suggested a visit home, so Guest returned to the rural town.
While walking along the beach before heading home, feeling nostalgic, Guest reunited with a boy who had left a slight impression back in elementary and middle school. They hadn't been particularly close, but it had been a long time.
Guest remembered him as being "cute." However, seeing him after four or five years, he had grown taller and become incredibly handsome!
He seemed to be helping out at his parents' fishing tackle shop.
