Hold on tight, y'all, it's LeaIsa Amnesia AU time
This is somewhat canon, except basically it eliminates kh3d and kh3, but Roxas and Xion are still present, as well. Soooo let's call it canon divergence lmao
Isa has woken up as himself again, but he's pretty much on his own. Honestly? He's okay with this. He thinks he's better off being on his own. Readjusting will be easier when he's the only one who has to put up with...well, him. It's not easy, though, and it takes a long while ~~
~~ After a few months, he gets into a normal routine. He's working and living his new life and tries not to think about the past. That also isn't easy, though, considering how much he misses Lea. That's another thing he tries not to think too much about ~~
~~ He does a damn good job at not thinking about it, too. Until...

He bumps into Lea on the street while walking home from work one evening. Literally walks right into him. He goes to apologise, but finds himself unable to speak because /holy shit/ Lea is standing right there ~~
~~ Only problem is that Lea doesn't seem fazed in the slightest. He chuckles and apologises and continues on his way. Isa, not knowing what's come over him, calls out to him and stops him. "Sorry, have we met before?" Lea tells him no and Isa's heart stops. His stomach drops ~~
~~ "Are you sure?" Isa asks because he refuses to accept that /no/ as a valid answer. Lea smiles "I think I'd remember meeting someone with that colour hair" "Yeah, well, your hair colour isn't all that common, either" Isa retorts ~~
~~ Lea apologises again and assures him they've never met before. Isa accepts defeat and lets him go. Isa then continues back to his apartment, but now he /really/ can't stop thinking about Lea. Can't believe Mr. Got-It-Memorised doesn't remember him ~~
~~ And if he doesn't remember Isa, then he must not remember anything about their time with Organisation. Well, actually, he seemingly doesn't remember anything before it, either. Isa tries to shake the thought from his mind. Maybe this is for the best ~~
~~ A few more days pass and each of those days Isa has to tell himself not to think about Lea. And when he gets home from work one night, he notices new neighbours have moved in across the hall from him. In his new life, he tries to be as friendly and approachable as possible ~~
~~ So he goes to introduce himelf to said new neighbours. What do ya know, it's Roxas and Xion. And they definitely remember Isa. Better/worse yet, they knew the new version of Lea. They're still all friends. They still all work together. Isa tries not to be jealous ~~
~~ Lucky for him, Isa piques Lea's interest. Again, he thinks that maybe this is for the best. Maybe they can rebuild their friendship without the weight of the past. Maybe it'll be even stronger than before. Isa can make up for the past in subtle ways ~~
~~ Except Roxas and Xion still don't want anything to do with Isa. And they definitely don't want Lea hanging out with him. Lea is his own person, though, and hangs out with Isa anyway. And they do rebuild their friendship. It's a fresh start, even if Lea doesn't know it ~~
~~ As time passes, they do develop stronger feelings for each other. Lea makes the first move and Isa so wants to be with him, but something about it feels wrong. All of a sudden, the fact that Lea doesn't remember makes it so much harder to be together ~~
~~ Turns out Isa doesn't want Lea to remember. He wants them to be able to grow together and learn from their past mistakes. He wants to be able to properly apologise to Lea. He wants Lea to understand why he has such horrible nightmares from time to time ~~
~~ They've had their fresh start, but Isa wants what they built before. He even wants the pieces from the rubble when everything collapsed around them. He doesn't fully understand why, but he does. It's just not the same when they don't have a past they can share ~~
~~ like they're supposed to have. So Isa tells Lea they can't be together. It kills him, but he knows it has to be said. And he hates that he can't explain to Lea as to why he feels that way. He tells Lea that he needs to remember first, but that doesn't make it any better ~~
~~ Lea wants more of an explanation, but Isa only turns him away. Another few weeks past and Isa is approached by Roxas and Xion. They tell him that Lea told them everything and even they don't understand why Isa had reacted the way he did ~~
~~ "Y'know, we kinda thought you were in love with him" they say, and Isa is kinda shocked by this. He hadn't been expecting them to be so upfront with him. He admits that they're right but that it feels wrong when Lea doesn't remember. Now they're the ones shocked ~~
~~ "Isn't the fact that he doesn't remember better for you? If he did remember, there's no telling how he'd feel. What if he doesn't want to forgive you?" Isa knows this is a possibility and it terrifies him to no end, but that's exactly why he wants Lea to remember ~~
~~ "I don't want Lea and I to develop a whole relationship and have him wake up one day with his memories of the past intact and regret the relationship. That wouldn't be fair to him." Roxas and Xion appreciate this response and it makes them see Isa in a whole new light ~~
~~ Another couple of weeks past and Lea shows up at Isa's apartment drunk. It's the first they've seen each other since Isa turned him down, but Lea is all over him. Or tries to be, anyway. Isa still tells him no and that it's not a good idea. Lea tries to change his mind ~~
~~ "Whatever doubts you have, I'm sure we can work through. C'mon, you know as well as I do that we're perfect for each other" Isa hates that Lea makes such a good point. It's so simple, but hearing him say that makes Isa want to just give in to the temptation ~~
~~ "You have to trust me when I tell you it's better this way" Isa says, somehow sticking to his gun. Lea doesn't like that response and goes to storm off. "Once you remember, we can go from there" That only pisses Lea off further ~~
~~ "How am I supposed to remember when I have no idea I even forgot anything??" Isa doesn't have an answer for this. Lea takes off and that's the end of it.

Isa stops hearing from Lea. He asks Roxas and Xion about him, but their answers are always the same ~~
~~ "He's doing fine. Keeping busy" Isa doesn't know what to make of this. It's hard enough for him to accept that he had to let go of Lea all over again; he at least needs to know that Lea will be happy in the long run. That he'll also come to realisation this is for the best ~~
~~ Isa continues living his life. He thinks about Lea more than he ever did before. There's one evening when the sunset was particularly beautiful that the night brings along a raging thunderstorm. And it's that night when Lea shows up at Isa's door again. "I remember" ~~
~~ Isa doesn't want to question. He only wants to pull Lea into a tight embrace, but he stops himself. Makes himself breathe. "What do you mean?" Lea explains that he had a dream that essentially seemed to be a series of flashbacks. A dream that pieced everything together ~~
~~ He's not sure what triggered it, but he knows that he woke up and he just...remembered. Isa's not sure he should believe him. Wants to believe him, of course, but he's almost afraid to. Lea reassures him that he truly does remember. He's /got it memorised/ ~~
~~ That's what breaks Isa down. No one, especially Lea, could ever say that ironically. Lea laughs as Isa practically throws himself at him. They hug and kiss as they're officially reunited, memories and all. But then Isa can't help but ask "How are you not angry with me?" ~~
~~ "Why would I be?" Isa scoffs at this response. "Please, don't be so dumb. I was awful before. You have every right and reason to be angry" "That's fair. And maybe I would've been when we first met again those few months ago had I remembered at the time." ~~
~~ "But I had the chance to get to know you all over again without the past effecting us. Plus, I've seen how you are with the kids. I know you feel terrible for how you treated them before. And I know you've done a lot to try to make up for it." ~~
~~ "Even if I didn't understand at the time, I do now. You're Isa again. /My/ Isa. And I could never stay angry at you." Isa doesn't know how to respond, but Lea doesn't give him the chance to anyhow. They're kissing again and everything just feels right in the world ~~
~~ Come the following morning, Isa still does apologise to Lea for everything that happened before. Lea tells him it's not necessary, but Isa disagrees. Then Lea thanks him for making them wait until he regained his memories to establish a relationship ~~
~~ "It really is better this way. Being able to reminisce and share our childhood. Even our trauma from the Organisation" Isa nods and asks how he'll approach Roxas and Xion now that he has his memories back. "Shit I haven't even thought of that yet" Isa chuckles. Typical Lea ~~
~~ Lea decides he'll figure it out one step at a time. Now that they all remember, though, he figures it'll be easier. Less tiptoeing around that the rest of them have to do. Isa truly is relieved that Lea regained his memories ~~
~~ He had been beginning to fear that they would never have the chance to be together. Now that they can be, though--now that they are--he knows he'll never let Lea go again. Even if, for some odd reason, he loses his memories again tomorrow, he'll stand by him ~~
~~ After all, Isa knows they can make it through anything. Hell, their relationship withstood the Organisation. So he knows he has nothing to fear. They can never stay angry. And no loss of memory can keep them apart. Lea and Isa will always find their way back to each other.
Holy fuck even I wasn't expecting this thread to go on for so long lmao my bad sorry y'all 😅😆😘💕✨💖
