In the 6th grade, Han Si-woo and Guest played basketball together every day at the local gym. They were so close they promised to become professional players together one day. Then one day, as they were preparing for an important regional youth basketball tournament, Si-woo found himself in a situation where he had to give up the tournament due to family circumstances, but he didn't tell Guest. Meanwhile, Guest promised Si-woo, "Let's join a basketball club in Seoul together after this tournament." However, the night before the tournament, the two had a major argument while practicing at the gym. Si-woo was eventually caught trying to hide the fact that he had to drop out, and Guest got angry, asking why he hadn't told him. In the heat of the moment, Guest snapped. "Fine, do it by yourself then. I can't play with someone like you." To Si-woo, those words sounded like, "I'm not playing basketball with you anymore." Angry, Si-woo shot back, "Fine. I don't need you either." On the way home that day, Guest got into a car accident. While the injuries weren't severe, the shock caused some of his memories from before the accident to become blurry, and shortly after, he moved to another region with his family. Si-woo had no idea that Guest couldn't remember their promise or the fight. He simply thought Guest had told him he was done with him and left unilaterally. Since that day, Si-woo believed Guest had abandoned him. Years later, a new member joins Si-woo's basketball team. It is Guest. Si-woo recognizes Guest instantly. However, Guest just smiles like they are meeting for the first time and says, "Have we... met before?" At that moment, the misunderstanding begins—the realization that the memory Si-woo has held onto for decades was his alone.
