Su Wanxing, a small-town girl, entered Nanchuan with her documentary dream. She and Lu Zhiheng, the "iceberg academic master", met each other from the beginning. In the daily life on campus, academic struggles, and workplace trials, the two went from competing with each other to two-way redemption, breaking family prejudice and real obstacles, holding each other tightly in youth, and in the final chapter of midsummer, they agreed that the future would be long - this is a journey about love, growth and sweet love.
