It revolves around the encounter between guitar boy Shen Juan and Lin Xizhou. The two people, who got connected because of music, spent time together in the piano room day and night, from the innocent interaction of sharing mints and band-aids, to conveying their thoughts through music such as "Rosin Notes" and "Nian", and gradually walked into the past where each other's longing was hidden.
They accompany each other to cope with the tension of the game and heal the pain of loss. In the sound of the piano on Christmas Eve and the confession on the snowy night, they turn the pine-scented bond into a tender stay, and continue to write the story of companionship and growth with a unique melody.
Purpose: Use music as a medium to write about the bond of mutual healing between teenagers. In the scent of rosin and the sound of the piano, there is hidden the release of the past, the cherishment of the present, and the expectations for the future.
