Lin Xingluo, a talented girl from the piano department of the Conservatory of Music, formed a "liangzi" with Jiang Yu, the male star of the swimming team of the Sports College, due to an own incident at the radio station. She mistakenly broadcast the conversation to the whole school complaining about his "big limbs and simple mind"; he responded by saying "he is tone-deaf and narcissistic". Two people who had nothing to do with each other were forced to work together to complete the campus art festival project. From mutual hostility to heart-warming, they composed a summer song about dreams, growth and first love at the most beautiful age of youth.
