This song is actually by Curtis Peoples & Tyler Hilton
They play the same notes but with different guitar tunings, I'll post both
I'm pretty sure the lyrics aren't a 100% right but that's what I could come up with

Watch them perform an acoustic version of the song here:

Tyler tunes his guitar half a step down and plays the chords you see on the lyrics ( G D Em7...)
Curtis's chords are found here 
http://www.ultimate-guitar.com/tabs/c/curtis_peoples/so_young_crd.htm
OR
To play Curtis's part, put a capo on the 4th fret and replace tyler's chords with curtis's

Em7
When we kiss it hit me with that warning 
Cadd9
Such a rush what a crush we'd only been gone 
Sneaking out in any kind of weather 
Screaming out we'll always be together 
looking back all we ever wanted 
was a crush with some fun baby we were so young

Verse 2:
Always made me better when we were together stronger when I had u close 
Was the beauty in the window princess of the shadows I remember more 
so much time since those days that passed us by I remember
