I think this song is about a boy and a girl who are too afraid to tell each other what they feel for each other. They don't know each other well, and they have different interests and lead different lives, but they feel something there. She walks away because he never tells her what he feels and they both have lives to live, and that's the end of relationship that never happened and the pictures that were never taken. The suspicion of reciprocal feelings is all they get.
