In Jianglin, a small industrial town divided by the Yangtze River and torn apart by the old and the new, high school seniors Zhou Jin and Chen Ye are two souls rubbed against the rough reality of life. Zhou Jin is a silent "question-solving machine" who uses precise formulas to calculate every cent of survival cost; Chen Ye is a self-exiled "urban exile" who uses rebellion to cover up the ruins of his heart. When they became front and back in the college entrance examination factory Jianglin No. 3 Middle School, a redemption that began with confrontation and ended in symbiosis quietly happened - this is not a story about love, but a living record of two teenagers entangled their roots in the cracks of reinforced concrete, and finally broke through the cracks and grew into trees. They used old lighters to light wet moths, shared a pair of headphones under an abandoned gantry crane, and used an old notebook to type out the code to the future on a rainy night. When the wildfire burns out, can the warmth of the embers illuminate each other's long lives?
Concept: "Love as a survival skill" - In rough reality, love is not romantic, but concrete actions: teaching the other person a question, handing an umbrella to the other person on a rainy night, and saying "I'll catch you" when the other person falls. It is a real force produced by the combination of weak people that can change the probability of survival.
