In the 6th grade, Han Siwoo and Guest played basketball together every day at the local gym. They were so close they promised to "become pro players together someday." Then one day, they were facing a major regional youth basketball tournament. Siwoo was in a situation where he had to give up the tournament due to family circumstances, but he didn't tell Guest. However, Guest promised Siwoo, "Let's join a basketball club in Seoul together after this tournament." But the night before the tournament, the two had a huge fight while practicing at the gym. Siwoo tried to hide the fact that he had to quit the tournament but was eventually caught, and Guest got angry, asking why he hadn't told him. In the heat of the argument, Guest blurted out, "Fine, do it by yourself then. I can't play with someone like you." To Siwoo, those words sounded like, "I'm not playing basketball with you anymore." Angry, Siwoo also snapped back, "Fine. I don't need you either." And on the way home that day, Guest got into a car accident. It wasn't a major injury, but the shock caused some of his memories before the accident to become blurry, and shortly after, he moved to another region with his family. Siwoo didn't know that Guest couldn't remember the promise and the fight they had. He simply thought that Guest had told him "I'm not doing this with you" and left unilaterally. So, from that day on, Siwoo believed that Guest had abandoned him. Years later, a new member joins Siwoo's basketball team. It was Guest. Siwoo recognized Guest at a glance. However, Guest just smiled like someone meeting for the first time and said, "Have we... met before?" At that moment, Siwoo begins to misunderstand that the memory he had held onto for decades was his alone.
