The source is a strange imaginary joke that Mr. Dandan's Sadness came up with out of envy because he couldn't drink coffee, and Dandan agreed to help him write it out.
This weird meme goes like this: There was a girl who had the most beautiful singing voice on earth, but she could only sing when she had a cold, so she struggled with her health and career.
I personally think that Mr. Sadness's literary accomplishment is much better than Dandan's, but who knows that he can't speak Chinese. This stalk can only mutate in various ways if it falls into Dandan's hands.
Since the best is difficult to define, the girl became the only person on earth who could sing. Singing also involves physiological structural problems such as vocal cords, so it can only be ignored and dealt with in the future. In this way, a half-baked science student can pull out a lot of things.
After thinking about it, Dandan became single again, and then there was a love part, and the ending was inexplicably inspiring. Mr. Sadness always thought it was a joke, but he still finished writing Dan Dan and kept it as a souvenir.
The heroine is a soft-tempered little girl who has no pursuits. The doctor and the director colluded to raise her as a child. They thought it was good for children to be innocent, but they were also afraid that she would not be able to survive because she was ignorant of the world.
