Full text introduction: Gu Yang, a talented student in the piano department of a top music conservatory, is famous for his superb skills and cold and distant temperament, and is known as the "Iceberg Player". His life plan is clear and cold: win international competitions, become a professional performer, and stay away from useless emotional ties. However, all this was completely disrupted one rainy night. He "picked up" a homeless girl who was soaked all over - Lin Xi, a piano genius with an absolute sense of pitch and a sincere love for music who could no longer play the piano due to an accident. The forced start of a "cohabitation" life suddenly brought two people from parallel worlds together. Gu Yang's world accustomed to order was gradually invaded and melted by Lin Xi's warmth, kindness and occasional clumsiness. He was forced to become her "temporary guardian" and musical guide, helping her rediscover the meaning of music and its future direction. In the process, his closed heartstrings were plucked by her unconsciously, playing a tender movement that had never been seen before. From campus to society, from youth to maturity, they face academic pressure, competition, family obstruction and confusion about their dreams together. This is a sweet love song about how to heal scars with love and how to become a better self because of one person. It is also a youth symphony poem written by two people, full of laughter, tears and moving melody.
