Si Yanting and Zhong Shuwen fell in love and had a son, Si Yan. When Zhong Shuwen learned that he was going to marry He Su, she left their child behind and disappeared. Si Yanting was forced to marry He Su. When Si Yan was five, He Su sent him abroad. Twelve years later, at seventeen, he returned to China and enrolled at Beicheng High School.
At the corner of the teaching building, Ran Yiqing hurried past with a stack of homework. Her notebooks suddenly slipped from her arms. She bent down in a rush to pick them up, and when she looked up, she met Si Yan's gaze. He did not move, only watched her. The wind swept through the camphor leaves, scattering them beside the fallen notebooks. That was where their story began.
After some things happened in Ran Yiqing's family, and after the things He Su said to him, she did not want to drag Si Yan down and asked him to break up. Four years of waiting came to an end when the wedding was over.
