The aloof and introverted top student Zhou Zhiyu and the shy guitar boy Ye Zhouhong become desk mates. From the tacit understanding of tackling problems side-by-side in the classroom to quiet companionship in the corner of the library, from the soft strumming and singing during the agricultural study bonfire night to rehearsing together for the campus singer competition, their mutual feelings quietly ferment in daily life. Yet the greenness and timidity of youths always leave the words "I like you" just short of being spoken. The plane tree wind passes by, secret thoughts hidden away—this is a story of unrequited love belonging exclusively to youth, short just a bit of courage.
