In Lin Yuan's orderly and black-and-white music world, Jiang Chen broke into his life like an abrupt and brilliant lightning, carrying a melody full of struggle and pain.
Lin Yuan is recognized as a top cellist by the Conservatory of Music. He is rational, precise and keeps a distance from others. Jiang Chen is a new transfer student, a talented but bruised composition genius. The band-aid on his forehead and the bruises on his wrists seem to be his unspeakable past. He has a unique "synesthesia" ability and can "see" the color of sound. His "Color Concerto" is colorful and broken, but full of amazing vitality.
An unexpected encounter in the piano room caused two parallel lines to intersect. At the professor's suggestion, Lin Yuan, who was not good at speaking, became a performer of Jiang Chen's works. Through weekly ensemble practice, the rational and restrained cellist began to try to understand the composer's colorful but scarred inner world. From Jiang Chen's description - D major is golden honey, F minor is dark purple bruises - he gradually pieced together the campus violence the other party suffered due to his sexual orientation and "difference", the pain of not being understood by his family, and the past of hasty escape.
Among the ruins, two lonely souls warmed and healed each other through musical notes. Lin Yuan used his calm cobalt blue tone to build a safe haven for Jiang Chen; Jiang Chen used his hopeful golden melody to add unprecedented color to Lin Yuan's black and white world. What they completed together was not only a concerto, but also a confession of courage, acceptance and love.
