To this day, Yan Xia can't forget the mutual acquaintance and love she had with him that summer. Unfortunately, before the college entrance examination, he chose to give up those hands. She did not allow herself to love humblely, and had to choose not to look back, thus completely becoming a stranger. After the college entrance examination, in order to escape from the past, Yan Xia resolutely applied for a key university in the north. He was alone in a strange place, thinking that he could forget the past and start over. However, four years later, Yan Xia returned to the provincial capital. Everything had changed, but he found that he had never changed in his own psychology, and he missed him more and more intensely. When they meet, can they put aside their past and start over, or will they go further and further away?
