The silver-white box contains the story of him and her. He never gave up, she never forgot, and it was never forgotten in that corner. The familiar school gate, the laughter and laughter year after year, has different faces year after year. Who was here smiling at someone's appearance, who was here silently watching someone's retreating figure, who was someone's scenery, who was decorating someone's dream, the breeze passed by, no one told. As time goes by and memories are covered in layers, that past event, those words, and the appearance of those people will eventually be blurred, leaving only the palpitating feeling at the beginning. Where is he at this moment? Where is she?
