I was just watching ABC and harry and ginny are said to have a crush that develop into young love which intensifies. 

I don’t know. but that is just awful. 

I think that it is completely different. I think Harry thought she was hot, and she was in and out of relationships, and that made him feel special. And I think that it made her think she was experienced and that at least one of them knew what was right. So they spent time together, and I think they were just meant to fit as they did and it was comfortable. And everything around them was so crazy that Harry could feed off that comfortable energy which made him think about her and from there it turned into real true love where they were able to find and know each other, then (in the biblical sense) know each other.
