Lin Xingluo, a gifted piano student at the conservatory, got into a "feud" with Jiang Yu, the swimming team's heartthrob at the sports college, after a mishap at the campus radio station. She accidentally broadcast her comment calling him "all brawn and no brains" to the entire school, and he fired back by calling her "tone-deaf and narcissistic." The two had never had anything to do with each other, but were forced to team up on a campus arts festival project. Their bickering turned into affection, and in the most beautiful years of their youth, they composed a summer song about dreams, growing up, and first love.
