After being involved in a car accident, Sihyun Sandara Park is left with no memories of the accident or her past. The accident causes her to see sounds in color which is often disorientating, forcing Sihyun to protect her ears. She encounters Jiwon Hong Ahreum in the hospital and moves in with her when she is later discharged.

Meanwhile, Jiil Han Jaesuk, a failed songwriter stumbles upon this score and offers to find the melody. They embark on a healing journey as they collaborate to complete Sihyun's melody.
