Okay so kinda rant incoming-
Let me start this off by saying that I'm not putting this out there to be hateful or anything, it's just a personal pet peeve, my opinion if you will. If you disagree with me, good for you for having free will, I'm proud of you. I don't hate anyone who does this, and I don't mean to sound hostile, but English is my second language, I already have no sense of tone in my native language, and also I'm overly passionate about shit that just doesn't matter. Take it with a grain of salt please.
Disclaimer out of the way, can I just say how much I hate when in fic Jouno's blindness just gets erased?? Specifically when there's just like an authors note saying "yeah I didn't make them blind" with no plot event to justify it? Specifically in a fic taking place in "present day" BSD where Jouno very much is blind, because I know they canonically became disabled later in life rather than being born like that. Fics exploring how they became blind? Muah, chefs kiss, intriguing. But I'm not talking about those.
It very much feels like it's just a cheap way to make Jouno impressed with how attractive their assigned love interest is (usually x reader but I've seen suegiku guilty of this too). As if that's the only thing that could possibly draw them to that person. Like screw personality, behaviour, idk- sound of voice or something, let's go the easy route! They see a hot person and immediately fall for them because that's easy! That's the only thing that could ever matter when being attracted to someone! /s
It's also erasing a pretty integral part of their character. Because as much as I don't like it, Jouno is a side/background character. They don't have many defining traits, and you're just throwing one of the few ones they do have out of the window for convenience. At that point it's not Jouno anymore, you just stripped off their name and appearance and pasted it onto generic anime boy template 3.
And if you're going to go through the trouble of writing an entire fic about them, am I wrong to assume you'd at least like them a little bit? Please? Why would you want to change them?? Even AUs and stuff keep the character intact in the context of how they happen. This isn't even usually an AU, it's just canon universe except idk the magical eye fairy "cured" them. ("Cure" in quotations, disabilities shouldn't be seen as something to be cured)
Of course, write whatever you like. Your fics are yours and you should write whatever you want to and not feel stopped by what I, random person on the internet, have to say about it. Write what you want to write, and I'll keep reading what I want to read. I just had to get the disbelief and frustration out my system.
