and why don't you like an extreme NTR ending where it makes you feel real hatred towards inoda ahah so weak people have become these days xd it would still become canon alicization and it wouldn't be bad.
Im fine with an extrem NTR ending but they way you pitched it is super unrefined and at most a bare concept.
Just the idea "Kirito should be in a wheelchair whiles Asuna and Indoa have sex" is just a scene and not an acutal story idea.
Lets take the one time you actually made this idea a bit more realized.
I expect a despicable ending such as cuckito ending up in a wheelchair because of problems with the server and asuna being destroyed by inoda in front of him.and inoda saying don't worry sempai we will take good care of you.
Kirito ending up in a wheelchair because of a server problem means that it would be just dumb luck and not even Inodas doing, meaning some of the crulty is lost.
Inoda showing any signs of sympathy by saying things like "we will take good care of you" is also a bizzarly backwards thing of him to do.
It also completely neglects any concept for FOG by having the only cruel thing be something that happens in the real world.
They are all in school together, they already spend most of their time in close proximity to eachother. Inoda lives literally next door to Kirito, it would be so easy to just have him be tourmented every night by always hearing Asuna the next room over and maybe constantly sending messages to Kiritos or have Kirito check Inodas blog with videos of them fucking.
