Names for characters

Ok, so I'm about to start writing a sci-fi romance trilogy. The first book is almost solidified, but I forgot one of the most imortant things; names! That's why I need your help. I need names for the two main characters, but if you could think up names...

for family, friends, etc, that would be awesome. The two main characters are a girl and a boy in their junior year of high school. The boy falls in love with the girl because of the facade she puts in front of herself; she makes herself seem fragile. (In reality, she does look like a pretty fragile person, but she isn't) The girl doesn't realise she has fallen in love with the guy until the near end of the book. Oh, right, the guy is popular. There are reasons for these two being the way they are, but if you want to read this you'll have to wait. If you do want to read it when I start to get it up, put a response in the coments telling me so and I'll funmail you the link. And if you can think of any names, that would be awesome! Thanks!
