What I think this song is about: I think it’s about a (most likely mute) girl (who is most likely going through some heavy things) who is in love with this boy, but he doesn’t know that and ignores her as if she is a corpse, all the girl wanted was to see the boy, eventually she falls into dispair, as love ‘chains her up’ (I noticed her foot was chained up to a heart in the PV), i also realized this song could also be a retelling of Hans Christian Andersons “The Little Mermaid” (Discalimer: I am *NOT* Talking about the Disney adaption with the happily ever after, I’m talking about the original where she gets her tounge ripped off by the sea witch) as the PV also makes multiple parallels with the little mermaid (the girl being ‘a drowning corpse’, a part on the PV where she has a mermaid’s tail later cutting to her having human legs ,etc), and maybe the reson why they use the use on water and drowning is becuse she is drowning in dispair and love, at the end, she most likely not commited sucide, but if she did, it is also an accurate to the oringinal version of little mermaid, at the end of the book, Ariel/ The little mermaid, Kills herself by drowning herself, and her corpse decays and vaporizes as seafoam, and later, she becomes a ‘Daugher of the wind ’ and in order to get reborn, she must do 100+ good deeds as a spirit.
