Singer-songwriter Kevin is in trouble ahead of the release of his new song. As he rides his bicycle to visit the place where he performed before his debut, Kevins mind recalls the events with the people he met on his bicycle trip in the past and he gets comforted and inspired by the times he spent with them. Kevin encounters an empty concert hall that is about to close. There, he completes his new song with the help of his best friend and colleague, Sang-wook, who died first in a car accident.
