A boy and a girl are friends... only to find out at the end they have loved each other the whole time
Too easy!! It is Ron and Hermoine from Harry Potter!
You might think that is an obvious choice but I love the Harry Potter series and I had been hoping that Ron and Hermonie would hook up for a long time. The chemistry was there and it was only a matter of time.. it just frustrated me that it took so long. But when it did it made me go "aawww".
Ok, back to my novel!
