Harry/Luna, Neville/Hermione or Krum/Hermione. I like how Luna and Harry shares some things. They know the feeling of having a love one part from them and see someone die before their eyes and be an outcast or that some people just don't get them. Some people misjudge Harry and Luna, think he's just the Boy-Who-Lived and that Luna's a lunatic (

sorry about that joke). They share a bond too, but it's not as strong as Harry and Hermione's.
And for Hermione/Neville, I always had a thought of Hermione having a soft spot for Neville. Well, helping people is very noble, but she helped him countless times and it's pretty nice of her. She doesn't think Neville's a weakling too, unlike how others think of him - almost-squib, worthless, etc. First, helping him find Trevor and then helping him in Potions and other situations. And then when he asks her first for the Yule Ball, I thought it was sweet *coughcozHarrywaschickentoaskhercough*. Apparently, I thought he had a crush on Hermione (since for me, Harry needed to open his eyes back at that time

) or that he needed to ask a girl he was close to in some way.
And then for Hermione/Krum, well, his treatment of Hermione was sweet. Some people see her as a know-it-all, but he must've seen something in her. Too bad though that she didn't quite return his feelings much. He was concerned about her in many fields (shall I say, her relationship with Harry?

) and it's very sweet of him. I felt sorry for him when he tried to get Hermione's attention who divulged it towards Harry. I liked how much Hermione was concerned for Harry at that scene, but Viktor, I thought he needed some love too.
Why I didn't say Ron/Hermione or Harry/Ginny? I don't hate the ships, really. But how Ron treated Hermione in the books was just odd. He made her cry, no apologies, and they end up with each other. And Harry/Ginny, I just ask myself if she knew the real Harry and not the BWL. And the fact that they had very little interaction, and then he fell for her, isn't realistic for me. Hormones my foot. Oops.

Just explaining why. No offense to R/Hr and H/G shippers.
So yeah, I'd accept Harry/Luna and Neville/Hermione or Krum/Hermione mostly. But no matter what, Harry/Hermione is in my heart. No replacing H/Hr. They don't have the effect Harmony has, even if they were combined.
