This is a bootleg. The official video's first four seconds are of a building that I'm at almost every other day.
I spent the day working and daydreaming of a girl who exists, but probably doesn't remember that I do. It's ok, because the version of her that I daydream about only exists in my head.
I'm sure that doesn't make much sense to you, but it does to me.
Music: why did you leave me here alone? Wait...
