Can you PLEASEEEEE do canon-divergent Ronarry?
Of course I can! I've slowly became more and more of a Rarry/Ronarry shipper, so this will be fun (also, thanks for the canon divergent part because I don't really know the timeline of things and it might get screwy (I haven't read the books in five years))
I mean, it technically started when they first met on the train, but I suppose it really started when Ron got upset about Rita Skeeter's rumours about Harry and Hermione being together. He assumed it was about being left out of the friend group, or about Harry getting even more fame, kind of like the jealousy he got when Harry became of Triwizard Tournament, but it wasn't either of those.
Ron gets a little bit more jealous as the rumours rage on, and so, when it comes down to him and Harry needing dates to the Yule Ball, Ron laughs and says "Why don't we just go together? It'll be a laugh," and Harry just looks him and says "Man, that's bloody brilliant! We'll make a joke out of the whole thing!" And Ron doesn't want it to just be a joke to Harry, but he'll live.
So they go together and get glared at Percy for dancing together and "making a mockery out of a sacred tradition" but Ron just flips him the bird and continues dancing with Harry. It's so much better than being uncomfortable all night with girls who would just feel unappreciated (in this universe, I believe Dean would have gone with Parvati, and well, Seamus went with Lavender, and maybe, just maybe, seeing Ron and Harry dance, gave those four the courage to dance with who they really want to dance this. And if we could have some Hermione x Padma, that'd be great too).
Also, Ron isn't even really upset when Viktor and Hermione come over to the table, because, well, he's distracted by Harry's laughter at the looks people are throwing them (maybe this could be where Hermione figures out, and gets a little upset, because she does like Ron, but she doesn't make a scene, she just walks out and Padma follows her).
Anyways. Come February, the rumours about Harry and Hermione are still going strong, but then Ron is Harry's most important person and of course Skeeter hears about this and about the Yule Ball and she starts up a different rumour. A rumour that isn't as much of a lie as the one about Harry and Hermione. And a ton of people start treating the two of them weird, start moving away from them in the hallways, and Hermione is just like, fuck her stupid crush on Ron, she is going to protect her best friends with everything she has and starts GSA kind of thing at Hogwarts and she makes it very clear that no one has to come out, and she doesn't try to force Harry and Ron to join or to realize their feelings because she knows they're not there yet. But she does ask them to join and they both do.
Ron joins, not because he thinks he's gay or bi, but because 1) Bill's bi, 2) Charlie is ace (something Charlie discovered by obsessing over tons of books about sexuality at a muggle library), and 3) he's trans and so is Ginny and nobody really knew because they transitioned so young but now, with Ginny's permission, they do. Harry joins because he always hated how the Dursleys talked about gay people.
Honestly, a ton of people join it.
Anyways, after Cedric dies, Ron can't speak to Harry all summer and he's kind of dying because "I have to talk to him 'Mione! I have to!" And Hermione is just like, 'when is this stupid boy going to realize he's in love with Harry'.
When Harry first sees Ron at Grimmauld Place, his first thought is to kiss him (he doesn't, of course), and he's just like 'where in bloody hell did that come from' because last Harry knew, he had a crush on Cho.
Not a lot happens between them in the fifth year, except that Ron is like, ready to kill Umbridge when he finds out what she's been doing to Harry, but that doesn't change much from actual canon.
There's also that one kiss with Cho, but in addition to her crying, he just didn't like it in general. He wasn't that attracted to Cho anymore. He never goes on a date with her.
But 6th year. Oof. Sixth year is a mess of sexual tension and stupid relationships. When Lavender starts flirting with Ron, he just goes with it, because Lavender is cute and sweet and he likes kissing her and Hermione is just like 'dude. wtf. Harry is right there.' And of course, Dean and Ginny get together.
Harry is super jealous and he thinks it's because Ginny and Dean are together, but after starting a thing with Seamus (because Seamus is also jealous and lonely) that lasts a lot longer than he expected it to, he realizes that he likes a different Weasley. But after accidently breaking up Dean and Ginny, he breaks it off with Seamus, and kisses Ginny for some reason (he really doesn't know why).
Anyways, while all this shit is going down, Hermione and Luna kissed sometime around Christmas, but they did 't get together. And instead of asking Cormac to Slughorn's party, Hermione invites Padma and they finally get together while Harry still takes Luna. Just a big gay mess, tbh.
There's a whole thing where Ginny has been slowly realizing her crush on Luna, and after Harry kisses her, she finally admits it, to herself and to everyone else. So, Linny is together.
Meanwhile, Ron and Lavender's relationship becomes more and more intense, and they even lose their virginity to each other, and they don't regret it but after he gets poisoned, he decides to break up with her because he realizes that he can't keep ignoring his feelings for Harry.
So, just to wrap it up, at the end of sixth year, only Hermione/Padma and Luna/Ginny are together, and the rest of our disaster gays are single.
During that summer, both Harry and Ron's feelings for each other grow and they stop being oblivious fucks in that respect but they have no idea that the other likes them.
Harry is happy to see Ron as part of the rescue team but is a little self conscious that Ron will be able to see his body.
They would have danced at Bill and Fleur's wedding but, like, Harry was disguised as Ron's cousin. It would have been weird.
I'm pretty sure that in this universe, Ron wouldn't leave, but the locket would still go after him, and it wouldn't even change it's speech that much, "I have seen your dreams, Ronald Weasley, and I have seen your fears. All you desire is possible, but all that you dread is also possible... Least loved, always, by the mother who craved a daughter... Least loved, now, by the boy who would prefer anyone over you..." and Ron casts a scared look at Harry and Harry finally realizes that Ron likes him back and kisses him right then and there and that's how Ron got the courage to destroy the locket.
Hermione is just, like, "Finally, the two idiots are together"
I'm gonna do a time skip to right before the Battle of Hogwarts because I can, and Dean, Luna, and Hermione finally see Seamus, Ginny, and Padma again and Seamus jumps into Dean's arms and kisses him. The other two couples reunite as well, and then Ron and Harry announce that their together, because they don't want to be a secret, not now, not ever. And everyone's just like "Hermioneeee! This isn't fair! You totally pushed them together!" And they all head over to give her her winnings, because yes, she made a betting pool.
When Ron makes the comment about needing to save the house elfs, I think Hermione would still kiss him, but it would be a friendly kiss. And Harry and Ron would kiss while crying before Harry headed into the forest, and Hermione would have to hold Ron back from running after him.
When Voldemort announces that Harry is dead, Ron let's out a blood curdling, eat splitting scream. And Harry is on his feet within seconds. Voldemort turns and before he even realizes it, he's screaming Stupefy and Voldemort is yelling out the killing curse and Voldemort's curse backfires because the Elder Wand us flying into his hands, and... Voldemort is dead. No big speeches. Just thirty seconds of a duel and it's over. And Ron is running towards him.
Time skip again. Fred and Lavender are both saved after near death experiences. Lavender and Parvati finally get together. Fred and Lee reveal that they've been together for years and are now engaged. Percy and Oliver are together. Everyone is gay.
Ron and Harry open up a wizarding orphanage together and help their friends adopt.
I'm sorry that at points this wasn't focused on Ronarry, but you gotta admit,,, it was worth it. Plus, I had to make everyone gay because that's what I do best.
