After a long session of practice you were already free to leave, oh, that would've been if Dazai wasn't already waiting for you outside the music room like every single day you had practice session, and if you didn’t he would wait for you by the entrance of the school building.

“You play so bad, I thought the window was gonna break”

He was just teasing, covering his adoration for you, one he wouldn't never admit that he had even if it was his last day on earth. He wasn’t one to show affection, but for you he would at least show interest.

Your relationship was something else for sure, no one understood at all if you hated or loved each other but that didn’t seem to bother either of you.

They didn’t need to know nor understand what you guys had.

But surely it was special.
