Jung Eunji had her life as a child better than anybody. She was only 7 years old when she realized that there will always be that one person who’ll stay beside her, her childhood friend, no, her current friend, no, her best friend forever, Jung Daehyun. They grew up together as a child in Busan. And talking, bickering and playing with each other with their accent would rather be amusing to see.

But what would happen when they were to be separated from each other’s side? Eunji’s parents need to move to Seoul for a business reason, leaving Daehyun behind. Will Eunji find someone else to be there by her side or still cherish her memories with her best friend Daehyun?
