High school student Yin Na's house was sold due to her family's debt, so she returned to live with her grandmother in the countryside. Yin Na's father, who went out to work, was suddenly injured and fell into a coma. Yin Na, who was in a bad mood, often went to the stream to be alone. One day, by chance, she met a young man by the stream - A Yuan. A Yuan was a ghost who could not remember his past life and had been wandering by the stream for ten years because he wanted to see his family. At A-yuan's request, Yin-na decided to help him find his family, and with A-yuan's help, Yin-na also entered their world from the dream to find his injured and comatose father. Yinna experienced all kinds of incredible things in that world, and met heroes, Uncle Cai, Yuanxin and others. She was surprised to find that these people knew Ayuan and Yinna's father. From their mouths, they gradually restored the truth about Yinna's father's injury and Ayuan's death ten years ago. Yin Na finally found her father. Dad and the hero will wake up in the hospital. When they wake up, they will tell all the truth. The culprits who killed A Yuan and hurt Yin Na's father will be punished. Ayuan also regained her memory, but Yinna found that she had a deeper relationship with Ayuan, but Yinna hid part of the truth and used white lies to let Ayuan leave to see her family in peace. After Yinna woke up from her dream, she received the news that Yinna's father had regained consciousness, and she felt more deeply the beauty and preciousness of life.
