Yinhua City is a northern city wrapped in thick fog and gelatinous moisture. The fog will never clear, just like some people will never speak.
Eighteen-year-old Qiu Wu stood on the rooftop of his senior year of high school, no longer smiling at anyone. Three years ago, she was the girl who would read out unfamiliar names aloud in front of the class list, run after someone, hold an umbrella and say "this umbrella is enough." Three years later, she put away all her strength and replaced all responses with a "hmm".
Seventeen-year-old Lu Tianqin kept soy milk behind her for three years. From silence to response, from avoidance to pursuit, when he finally learned to speak, she had stopped where she was. She waited for so long that the part she "liked" was used up and turned into a cup of cool soy milk.
In the past three years, he has taken two steps back, and she has walked through four seasons. Qiu Wu changed from a burning flame to a dead tree, and Lu Tianqin changed from a silent stone to a person chasing the light. The distance between them is not distance, but a year - he didn't dare to get close to her when she was still enthusiastic, but he knew that she was already tired when he rushed to her.
A secret love that has always been misplaced, a youth sealed by fog. She kept the keys to his house but booked a ticket south.
The fog condenses but never disperses. Her secret love was gone, but his secret love had just begun.
Concept: Not all sincerity can be caught at the same time, but every silent love truly changes a person.
