(the name of the song in this chat is from another band au chat I found)
You and Dazai were part of a two person band. You did guitar mostly, but sometimes you and him took turns singing in concerts.
It was a pretty popular band, high in the charts. Millions of fans across the world loved the music you two made.
In a world tour you were having, there was one song in particular the fans begged you to play. The Silence After You. It sounded different than your other songs. It was about this couple that broke up and both miss each other.
Most of the song had the background music, you playing guitar, and the both of you singing back and forth between each other.
"The silence after... youuu-"
Dazai cut off at his part so you could sing the 'oooh' part after it. But with no guitar strum and no reply, Dazai looked over at you. This wasn't supposed to happen. You shouldn't be responding to his part with literal silence..
Dazai realized how pale you looked. Something was definitely wrong. The crowd around the stage all looked around at each other, all equally confused on what was happening.
