Rain or Shine

Rain or Shine is the ending song of 91 Days, performed by Elisa. The song was released as a TV-size digital single before being included in two albums, a regular CD-only edition and a limited edition that included both a CD and DVD.

Though the lyrics to the song are simply "la la la," in some episodes the tune varies, such as Day 8 where the melody is slower.
