One Direction - If I Could Fly Lyrics Meaning

If I Could Fly is so clearly about Larry I can't even explain it.

Louis was on the other side of the world writing Home when Harry was writing this.
Louis has a tattoo of a compass that points to Home. Harry has a ship. That's a matching tattoo. (Also a lot of people consider Home as Louis's "coming out song".)
Louis was always in a beard relationship (whether it be with Danielle or Eleanor or whoever) because he's trying to protect Harry from having to go through that, but it also means Louis can't be "home" a lot.
IICF is about how they wanna escape from management to be with each other.
By the end of the song, they stop using pronouns.
"I'm missing half of me" is one of Harry's lines. I read somewhere that Louis co-wrote Half A Heart. We know damn well these boys don't pull coincidences like that.
"For your eyes only, I'll show you my heart" is another one of Harry's lines. Harry has said, on MANY occasions, that he loves Louis's eyes (who wouldn't they're gorgeous), not to mention, in Harry's music video for Golden, we all know that his suit was literally what this fandom calls "Lou Blue".

I rest my case.

If you don't think this is about Larry, I'd like to know the reasoning behind why you think it's not.
That's all, tpwk :)
