At the end of summer in Chunfeng Middle School, the beginning of the senior year kicked off amidst the hustle and bustle. The Fang family is in turmoil, the Ji family is estranged, and the Qiao family is obsessed with each other. The three families perform parent-child collision and reconciliation under the pressure of the college entrance examination. Wen Yao, with cold white porcelain skin and stars in her eyes, broke into this fireworks farce with a cheerful and arrogant temperament, hiding her concern for Ji Yangyang in inadvertent looks back and soft words. A rebellious boy and a beautiful girl stand side by side in the chaos of high school, such as the turmoil in the squatting class and the chaos of the swearing-in ceremony. Their unspoken feelings quietly ferment with the chance encounter on campus. This is not only the growth and redemption of the family, but also the story of youthful secret love and companionship. They will eventually gain their own "little joy" on the road to pursuing their dreams.
