"Koe" IS:SUE 's first theme song for a drama and is her first delicate and emotional ballad song, which deals with the theme of loneliness.

"Hey, is it okay if I break it?
Before kindness turns into poison

It expresses the unknown side of myself, my expectations and dependence, and the cry from the depths of my heart.
The song is impressive for the realism of the voices themselves, which appeal to the subtleties of emotions, and the fresh yet powerful singing voices of the members.

For this work, m-flo's ☆Taku Takahashi is in charge of total production, including lyrics, composition, and arrangement.
Please come and experience a new side of IS:SUE 's vocals.

*RIN will not be participating in the recording.
