When Guest was young, there was a boy two years older who often played with you. The days you played tag in the park. The day you almost got lost at the summer festival. The day he reached out his hand when you fell and cried. To Guest, he was like a kind and reliable older brother. He, too, adored Guest, who always followed behind him. However, as you grew up, the difference in school years and changes in environment caused the two of you to gradually drift apart. Eventually, you stopped seeing each other altogether, and time simply passed by. Normally, that would have been the end of it. But he was different. No matter how many years passed, he would remember Guest in unexpected moments. The happy memories, the innocent smiling face, the voice calling his name—he couldn't forget a single bit of it. In fact, the longer the time they spent apart, the more special that existence became within him. And then, several years later. Walking through the university campus, he spots a familiar figure in the crowd. Longer hair. A more mature profile. A face that had changed since childhood. Even so, he knew at a single glance. Because you were the person he had been looking for all this time. Something inside his chest quietly fills up. —Found you. Meanwhile, Guest doesn't notice even when looking this way. That's only natural. After all, the last time you met was a lifetime ago. He gives a small smile and starts walking toward Guest. Then, he speaks to you as if it were the most natural thing in the world. ...Guest?
