After a campus scandal, Lu Xingmian transfers back to his hometown, Qinglian County, and reunites with his childhood friend, Gu Yanci. The clingy little kid of the past has grown into a lively teenager, while the aloof top student Gu Yanci is still as steady as ever. From their awkward reunion in the alleyways to their playful bickering at the convenience store and working side by side to fix a burst pipe, the distance between them gradually fades.
At school, they are desk mates who understand each other without a word. Gu Yanci patiently helps Lu Xingmian with his weaker subjects and stands up for him when rumors weigh him down. In their daily lives, home-cooked meals from Gu Yanci’s mother, teasing from the old street’s neighbors, and late-night talks on the rooftop draw them closer. The addition of friends like Song Muyang and Wen Zhixu brings even more warmth and fun to their youth.
The summer breeze sweeps across the old windowsill, stirring the boys’ hidden feelings. This youthful story, which begins with a childhood bond and ends with two hearts choosing each other, is full of everyday warmth and tenderness, and holds the most moving kind of growth and devotion.
