That has to be one of the most adorable nerd love song I’ve ever heard! The music video features the story of Stormtrooper TK-22304 on a mission to find true love!
The background story of the lyrics is that of a Stormtrooper getting deserted on an unknown planet. There he meets a woman and they fall in love. Later, he has to return to battle and she is left behind, with their child.
The song is a metaphor for two people who are fundamentally different. One being idealistic and of the sky while the other is practical and of the land and how they can only be together for a short while, before drifting apart.
