Deeper meaning: when there is fate, I can see you and notice you in the vast sea of people. When I missed the opportunity, although I saw you in the crowd, I just "saw" you. At this time, you are just a passer-by to me at best.
It can also be understood as: fate came, I saw you in the crowd, just to see you; Fate is over, I can still see you in the crowd. You're just a passer-by. You just saw it.
