I don't think there's any girl except Hermione who will be right for Ron.They are made for each other and are perfectly perfect with each other.Romione is the best couple in the world, in my opinion.I luv the quarrels they had which they made up later and and so on... But here if آپ ask me, Luna'll be right(just if Hermione is not in this world).
I'd just like to preface my answer سے طرف کی saying that I think Romione is the best Harry Potter couple and that the two are definitely suited for each other based on the way that Jo let their relationship develop.
With that said, I also quite like RonLuna. I think the few interactions they have together are really entertaining and I think they would handle each other well. Luna thinks Ron's hilarious, which would do wonders for his ego. And I think Ron would really enjoy teasing Luna for the rest of their lives.
I know, weird and random, and you're all probably thinking "WTF?!", but...You know...It's one of the many I have planned out for him.
Don't get me wrong, Romione (Sp?) is great! It's like what they say, opposites attract. But I just like seeing him in couples where it's totally unexpected. Things that'll get his family mad (like a Slytherin) and someone who isn't talked about a lot, like Daphne Greengrass.
Don't know, she's the first person who came to mind. I just find it interesting, that's all. Totally randoom, but no hating (though آپ can put up تبصرے ABOUT it, like your opinions on it), since it's just my opinion.
