Everyone has their own youth story, each with its own splendor. What I want to describe is a poignant love story between young friends in their youthful years. There are tears, humor, brothers, true love, and the confusion we once had... The love story between the hero Du Zihao and the heroine has not really begun yet. However, his good friend Fatty unexpectedly fell ill and died. Fatty passed away quietly before his love blossomed and before he faced the college entrance examination, the first issue in his life... Fatty's love and ideals became the turning point in Du Zihao's life, which made the story even more twists and turns. Youth is fleeting, but our youthful faith remains in our hearts forever! Come on! Sao Nian!
