Due to a turmoil on campus, Lu Xingmian transferred school and returned to his hometown of Qinglian County, where he reunited with his childhood friend Gu Yanci. The clingy little kid in the past has grown into a lively young man, and the aloof academic tyrant Gu Yanci is still calm. The two have gone from an awkward reunion in an alley to arguing with each other in a convenience store and working side by side during water pipe repairs, and their alienation has slowly faded away.
On campus, they were tablemates with a tacit understanding. Gu Yanci patiently tutored Lu Xingmian in his weak subjects, and stood up for him when he was troubled by rumors. In life, Gu's mother's hot meals, the jokes from the neighbors on the street, and the late-night talks on the rooftop made the two people bond gradually. The joining of friends such as Song Muyang and Wen Zhixu made youth more lively and warm.
The summer wind blows past the old window sill, blowing away the young man's thoughts. This youth story, which began with childhood fate and finally went in both directions, is full of fireworks and tenderness, and hides the most touching growth and protection.
