We see it in the movies...But does it really work/happen?

When two people who are pretty much completely different end up together. Like a prep and a punk, or a rich person and a farmer, etc. I never see this. I only see couples who look the same and it’s been set in my mind that people have to look good together to be able to be a good couple. But now, I think I’m starting to really like this boy but he is so plain and normal on the outside and we have nothing in common. I, on the otherhand, dress really weird and have facial peircings and tattoos. Should I even consider something happening between us or are images/appearances too much of an issue in real life? Have you ever seen opposite couples? Am I just superficial and thinking too much about the outside of things?
