The story is a love story that lasts six years from the second grade of high school to the graduation of college. In these six years, they experienced youth ignorance, innocence and ignorance, and gradually matured after going through college. However, in their hearts they still long for the kind of pure love. This kind of innocence does not mean that they have to come together, but that they have each other in their hearts. Mandy met Lin Jiyang at an art exhibition and was not dependent on him at first, just a friendship like a friend. After Lin Jiyang's long-term pursuit and attachment, she would say some things to him, but never express it. Mandy began to pay attention to Jiyang's behavior in her third year of high school, and her first love affair affected her studies. She wanted to cut off contact and wait until the college entrance examination was over before getting in touch with Jiyang. Ji Yang began to think about her, and the two agreed to study hard in the future, apply for the same university, and then openly fall in love.
