In this life, he is determined to work diligently and turn his fate around against all odds. When faced with injustice, he stands up for what is right; when facing the future, he remains steadfast in his goals. He and his close school friend support each other and fight side by side, eventually gaining admission to top universities. At university, they put their knowledge into practice and join forces to start businesses. After overcoming numerous challenges, they turn a small shop into a chain and develop a studio into a technology company. From innocence to maturity, from ordinary lives to brilliance—this is the story of two young men who make the most of their youth and strive for a better future.
