Character Based Challenge: Day 7

Who is the most unbelievable romantic couple?


This is a tough one as I actually do like most of the romantic couples I come across in literature.  I'm trying to think of all the couples I've come across.  I could go with Bella and Edward, but I don't want to have anything Twilight related in my blog, nor have I actually read the books.  It's not so much which couple I dislike, but the one I find to be the most unbelievable.  You know what?  I find Dean Thomas and Ginny Weasley unbelievable.  I like them together, but when I get down to the nitty gritty it's like, what?  Dean is friends with Ron.  He's not close like he is with Seamus or like Ron is with Harry, but they do room together, and I have noticed in the series that they are friendly.  They are on the Quidditch team together.  He's a nice guy.  I'm surprised he goes on to date Ginny without discussing it with Ron.  I guess that's where the unbelievable part comes in.  It doesn't look like Dean takes into account Ron and Harry's thoughts and feelings on the issue.  I can see Ginny being the younger sister acting like she doesn't care what her brother thinks and that if she dates someone in Harry's dorm it would get his attention.  I just don't see how the nice guy Dean can date a dormmate's sister without talking to him.
