“100 Letters” is a pop power ballad describing the story of two lovers who try to work out their failing relationship. The song uses Greek mythology, like the legend of King Midas, to develop the narrative.

Halsey said that “100 Letters” was the first song she wrote off the album, stating it was similar to the prologue of Romeo + Juliet where the narrator spoils the ending of the story:

It’s like me saying, hey we break up and I don’t give him anything but here’s the album.

Halsey hid a minute long snippet on her website before the album was released.

On June 1st, Halsey performed the entirety of hopeless fountain kingdom album for VEVO: Presents. Watch “100 Letters” below:
