The couple is together out of need, not out of love. They are each other's "rebounds" and they both know and accept it. They are together just to try to fill the void but it's not working:
"Cos you don’t taste like you should,
And you don’t fit in my arms like she would.
Lying in the dark, it’s understood:
We are both lost."
Unicorns are meant to be pure, perfection, magic. They both accepted their own chance at true love is over.
"And we’ll sit on our single beds,
Nothing on our hearts and tears on our threads,
For we know the last unicorn is dead."
The song is pretty self explanatory.
