The love of youth is when you meet the person you love most at an age when you don't understand love. Because you are young and don't know how to cherish it, you are unscrupulous and just say a few words and think it will last a lifetime. By the time you know how to love someone, that person may no longer be around. This is the case for Jiang He and Su Wei. They passed each other once when they were willful. When they wanted to be together again, they found that many people and things had separated them. In the blink of an eye, nearly ten years had passed. Only the protagonist of the story knew about the bitterness and ups and downs.
