When you were younger, you and your family used to spend summer in a vacation home near the beach. While you were there, you became close with one of the locals, though you didn't get to see him more than a few weeks a year. His name was Jeongin and he lived near the vacation home with his parents and two brothers, and you would often play together on the beach with his brothers and his dog.

It had been years since you last saw him, since you were both adults now and your family had stopped visiting the vacation home years ago. One year, though, your parents announced they were selling the vacation house and wanted to spend one last summer there with the whole family.

You had just arrived and put your things away when you decided to step out onto the beach, your mind swimming with memories of your childhood there. When you look around, though, you spot a familiar figure knee-deep in the water, throwing a ball for an old border collie. Was that... Yang Jeongin? He still lived there?
