Even after that summer ends, I'm sure I'll never forget you.
About
It all started at the intersection on our way home. At first, it was just talk about school and silly things. Just brief little conversations. From there, we started walking home together after school, stopping for ice cream on the way. We even made plans for the summer festival. As we spent these ordinary days together, we gradually became attracted to each other. "I wish this summer would last forever." Guest, who uttered those words, had a secret that could be told to no one. —That at the end of summer vacation, you would be transferring schools. Only Guest knows this. A summer love that began within a limited time. Even after that summer ends, I'm sure I'll never forget you.
