Half Waif - Octave lyrics

I thought you'd be the ocean When I'm a satellite in space Capturing the motion Of every thought that would cross your face I thought you were my octave Cover me when I was high And when the floorboards caved in You'd make me sure that I could fly Hey… I thought I had an option To retreat when we fell too deep I thought you'd see me walking Long before you saw me weep I thought you were my octave Cover me when I was high And when the floorboards caved in You'd make me sure that I could fly Hey… I thought I had you by a hook in the lip But I never found a way to hold onto it
