It was only a dream, but she thought she really had been with him. When she woke, all her fantasies shattered, leaving not a trace. The more you care, the more deeply you'll be hurt in the end. Fortunately, she didn't stubbornly cling to him. In the end, she let go. He had never loved her. She was just a passerby in his life, one of the many people he could forget. When she cared, she couldn't help herself. Once she stopped caring, she truly let go. If she could, she would never remember that summer again.
