Many years later, while sorting out old things, Lin Shiyin found a crumpled folk music festival ticket. On the back of the ticket stub is a lyric written by Chen Xiansheng in pencil. He suddenly remembered that summer, standing under the tassel tree, holding the guitar and playing the song "The Parade of the White Pigeon" by the band Lost Train. At that time, they would hand each other water on the badminton court and wipe the sweat from their foreheads; they would share a pair of headphones and listen to the same ballad at the convenience store in the alley. But later, they lost each other because of a misunderstanding. Until the reunion many years later, Chen Xiansheng picked up the acoustic guitar again and played the unfinished song. This time, they finally learned to be honest, and those missed times and unspoken words will eventually be reconciled one by one with the strings of the acoustic guitar on this summer afternoon.
Concept: At a folk music festival, Chen Xiansheng, who was holding an old acoustic guitar, met Lin Mianyin, who listened carefully. In the summer of the two teenagers, there was an unspoken agreement.
