The story is that the two friends play music for each other but the boy died and everyone kept telling her that "you cant play music for a living" so she didnt have a reason to play music anymore so she gave up on music.. Hope that wasnt repetitive with all the "musics"

it might not be accurate cuz i didnt watch the official mv my sis just told me the story

nobody panick she didnt die but he did?? so

and,, the paper was a music sheet aha
