at the orange (tree) i came out to see you
the citrus plant leaves were covering your eyes (so she was like standing under the tree)

put your head lower (so the leaves won't cover her so he can see her) 'cause my longing for you burns
the air smelt of crops, oh the scent of oranges

it was us two, oh you are like a deer (fragile animal supposed to mean a nice looking girl or something like that)
above our heads girl the flowers were dancing together
