There had been people talking recently, the top floor of the school where barely anyone would go, there were rumours it was haunted, people had heard music up there after school, no one knew why that was playing and no one wanted to find out it seemed, it made you glad, only you knew, you were the music that was playing, you played your instrument, you sung, you were under pressure to try and be the best in your own hobby, much like Kageyama, who was tracking up the stairs with Hinata, who'd insisted 'we have to see the ghost, it'll be so cool!', they both stopped in their tracks when they saw you in that empty room, facing away from them and at the window as you sung to yourself
"Don't." Kageyama mutters almost inaudibly as he puts his arm in front of Hinata, Hinata wouldn't ruin this for him, he had to watch for at least a little before they both made you aware of their presence
