The young girl Zaoyue was overcome with grief because her boyfriend died in a traffic accident. She got up and ran every morning in the hope of relieving her inner sadness a little. Also because of running, she met the strange man Pulo, which led to an once-in-a-century sight: in the early morning mist, she vaguely saw her boyfriend smiling and waving goodbye to her, and then faded away. This special reunion fulfilled the nostalgic heart of the early moon, so that she was able to face the real life again.
