The Sound (2017) Plot Summary & Ending Explained

The ending of "The Sound of Magic" reveals that Ri Eul, also known as Ryu Min Hyuk, is a complex character with a troubled past. Throughout the series, it becomes clear that he is a genuine magician who has been misunderstood. When he is wrongly suspected of a crime — specifically, the murder of Ha Yeon — the truth comes to light thanks to evidence from CCTV footage that implicates the store owner, not Ri Eul. This clears his name, allowing him to disappear from the police’s grasp and continue living his life in hiding.

As the story concludes, Ah Yi and Il Deong manage to confront Ri Eul just before he is arrested. She performs a final magic trick, helping him to vanish and escape the authorities. In this act, she symbolizes not just her belief in his innocence but also her desire to preserve his freedom and mysterious nature. Afterward, the series jumps ahead two years, showing Ah Yi thriving—attending college, working multiple part-time jobs, and performing magic tricks herself, which signifies her healing and path toward independence. Although Ri Eul's exact whereabouts remain unknown, Ah Yi still feels connected to him. She continues to send messages to the "magical" letterbox he once told her about, believing that he might still read her words.
