At seventeen, Su Nian and Cheng Yan planted the seeds of first love by passing notes in their high school classroom. One was quiet but gentle, the other bright and brave. With the purest of hearts, they stayed by each other’s side through their youth. But after the college entrance exams, the distance between north and south, their different family backgrounds, and their diverging dreams slowly wore cracks into their love. They tried and struggled, but in the end, they chose to let go with one last embrace at the airport. Ten years later, Cheng Yan’s wedding invitation arrived in Su Nian’s hands. She went to the wedding, and they exchanged smiles amid the applause and congratulations. In that moment, they finally understood: some people come into our lives not to be ours, but to light the way for a part of our journey. When love reaches its end, letting go is the finest way to wish each other well.
