Plot
19-year-old Hinako Mukaimizu moves to an oceanside town to attend college and indulge in her hobby, surfing, without much thought to her future. When her new apartment catches on fire, she is rescued by Minato Hinageshi, a 21-year-old firefighter with a strong sense of justice. Hinako is drawn to his dependable personality, and they bond when he begins learning how to surf. As the two spend time together, they fall in love; however, when Minato goes surfing during a storm, he drowns while rescuing a person.

Hinako is distraught with his death, but one day, she finds out that he appears in water whenever she sings "Brand New Story", a song the two of them often sang together. Initially happy she can see him again, Hinako later learns that he cannot be free unless she is able to move on with her life.
