A piano arrangement of the song "勘冴えて悔しいわ" (Kan Saete Kuyashiiwa) from ずっと真夜中でいいのに (Zutomayo). Sheet & MIDI available for download.

This song's English name, too, is uncertain. The lyrics are quite interesting, especially towards the end, where it gets more... morbid, so to speak. Hence the illustration choice.

Enjoy!
