Lin Wan, a girl from a musical family who was hearing-impaired for some reason, met Lu Chen, a genius game producer who seemed unruly but was actually deeply traumatized in college. Due to an unexpected encounter in a "sound experiment", the two went from not understanding each other to becoming the "only voice" in each other's world. They worked together to overcome the confusion of youth, the resistance of the family and the pain of growing up, and finally shined brightly in their respective fields, and also allowed their love to blossom.
