Luna Lovegood
Ginny was busy wandering through the debris-filled corridors of Hogwarts. The Second Wizarding War ended yesterday and the cleanup was still in progress. Ginny was looking for Harry and decided that now was the time to get back together with him. The Weasley girl found Harry up on the Astronomy Tower, since his untidy black hair was extremely noticeable. Ginny felt her body trembling in rage to see that Harry was accompanied by Luna Lovegood, since the Weasley girl knew about her supposed best friend's dirty-blonde hair, butterbeer-cork necklace, and radish earrings. Ginny kept her anger in check (not wanting to look like a bad guy) and walked up to Harry and Luna with an exaggerated sweet smile on her face.
"There you are, Harry!" Ginny blurted out in a falsely sweet voice, continuing to show off the exaggerated smile.
"You're no longer welcome to hang around with me, Ginny," Harry replied in an angry voice. "I can't believe that you would go behind my back and shag random guys. Your treatment towards Dean in particular made it even more clear, especially when you started 'dating' him shortly after breaking up with Michael Corner. I have no use for someone who enjoys toying with others' feelings, being a bully, a spoiled brat, and nothing but a coward."
"Yes, Ginny, all that describes you," said Luna in a matter-of-fact voice. "Since you never got attacked."
"That Lestrange woman attacked me with the killing curse!" snapped Ginny, her teeth gritting in anger.
"You were unscathed, Ginny," stated Luna. "Which meant that you went off to hide somewhere because you were more concerned about saving your own skin. Everyone else, myself, included, had some kind of injury, but you basically had none."
"Ohhhhhhhhhhh! Uhhhhhhhhhhhhhhh!" Ginny moaned as she grasped her left knee, trying her best to look hurt by limping.
"Nice try, Ginny." Harry replied in an exasperated voice, rolling his eyes at the same time. "Your bullying nature was proven when you first called Luna by that so-called nickname, Loony. You even nicknamed your sister-in-law 'phlegm.' How can you be so heartless to do that?"
"I've made it up for it, Harry!" Ginny whined, dropping the fake injury ruse. "I've been a good girl in waiting for you to come back. Was I not?"
"Your lack of enthusiasm over my return proves differently, Ginny," stated Harry. "You even fiercely insisted that Luna accompany me to Ravenclaw Tower instead of Cho."
"What you assumed was my cooperation was actually part of the plan Harry, Cho and I came up with," Luna revealed with a delighted grin, as Harry nodded his head in confirmation. "Harry and Cho made up and the three of us decided to remain friends. Cho's disappointed expression was to throw you off track and the plan actually worked."
Ginny was so furious that she charged towards Luna to strangle her. Luna whipped her wand out to cast the bounce-back charm, while Harry whipped his repaired wand out and cast 'finite incantatem' to cancel any charms that Ginny might've cast on herself to keep up the scarless beauty all over herself. Then Harry and Luna widened their eyes in shock when Ginny reverted back into her original form. It turned out that Ginny was actually an obese girl, rather than a skinny girl that she always claimed to be. Not only that, but Ginny also turned out to be under a charm to make her outer beauty as pretty as possible, but even that turned out to be a ruse. Ginny's jaw dropped open in utter shock and humiliation, now that her secrets were exposed to Harry.
"A spoiled brat indeed!" Harry responded in a triumphant voice. "Your mother must've given you countless sweets and other kinds of unhealthy food and beverages over the years. Your bullying and name-calling never got you punished. It's clear that your mother favoured you most of all. Fred and George told me that and how your mother always wanted a daughter, which makes your spoiled brat nature very reasonable."
"You've once again proven how pathetic you really were, Ginny," said Luna. "Even your so-called magical skills and quidditch skills must've been by pure luck somehow. Molding yourself to Harry's desires and interests to get him to like you was a very lowly thing to do, since that's a form of manipulation."
Ginny was so humiliated that her morbid obesity was exposed and the glamour charms she'd been under to look like a pretty girl at an average weight were cancelled, to the point where she turned around and burst into tears as she lowered her tear-filled eyes to the ground. She was sobbing so loudly that she didn't hear Harry and Luna cast more charms on her to prevent her from being able to cast more glamour charms on herself for a full sixty minutes, as Ginny walked away. As soon as Ginny was out of sight, Luna wrapped her arms around the back of Harry's neck just as Harry placed his hands on her waist, then the two shared a passionate kiss for a full sixty seconds.
"That was wonderful, Luna!" Harry praised. "I never knew that you were good at kissing."
"Well, I'm not unique for nothing, Harry." Luna replied with a smile on her face. "I'm getting hungry, I could go for some pudding."
Harry nodded his head with a smile at the suggestion (as he realized he was getting hungry, too). So Harry and Luna left the Astronomy Tower and started heading to the school kitchens, hand in hand. Now that Ginny was finally dealt with, Harry was free to be with someone who cared about him and wanted to be with him for just Harry. For once, things were working out in Harry's favour.
The End!
Author's note: I'd like to give a shoutout to the user 'redgreeneyes' for suggesting that Ginny be under the glamour charm to keep up appearances in the form of being morbidly obese being hidden by making her look like she was average weight, and to keep her ordinary plain-looking physical appearance hidden by means of enhancing her outer beauty artificially.
