Of course, here is my polished version of this copy, making its emotions more delicate and the characters more infectious, while enhancing the attractiveness and resonance of the story: --- The summer is hot and the heat is rushing. For Zheng Yuan, a photographer who is more than 30 years old, who is suffering from a terminal illness, the cold winter of life has already quietly arrived.In the countdown of fate, he accidentally encounters a young traffic policeman - a man who is not yet aware of his condition.A cautious feeling emerged between the two, as if it was quietly blooming in the cracks of time.However, under the shadow of truth and parting, is this newly-starred relationship destined to wither before it blooms? --- If you have more background settings or character details, I can further optimize the copy to make it more in line with the overall style and emotional tone.
