Standard tuning, capo on 4th fret.

Chords relative to the capo are D/B, D, D/E, G


D/B: x2023x
D: xx023x
D/E: xx223x
G: 3x003x

You can leave the top sting open, mute it or fret it to fill out those chords, either option works. When you start strumming later in the song you can fill those chords out even more by adding the A string.

"D/B" is Bm7.

"D/E" is Asus4, x0(2)23x. (parentheses because the note isn't played until she starts strumming).
Glad to cross paths with you on this adventure called life

lots of flirting with the other key without confirming. JUST LIKE THEIR LOVE IN THE MOVIE OH DAMN.
