What do you feel about the manhwa/ga/hua changing the contents from the light novel?

I personally absolutely hate it. I hate that now there's something that's canon but not really. I hate uncertainty.

People say that it's giving life or some features to add originality to the work but idk man, just make a new AU atp, it's supposed to be an adaptation, not a new story.

I'm fine with thes works cutting off some scenes from the novel, cause yea if the scene/arc wasn't too important, that's fair and also is a good excuse for people to read the novel. It's usually just extending the character building.

But making a whole damn shit that's so fkin different from the og source material is just so ass. Wtf am i even supposed to believe atp, it's like you like a character in one and don't in the other so literally wtf am i supposed to fkin feel. Fuck this shit.

And this is not something I'm pulling out my ass, a story i read has changes regarding a persons relationship and their personality too, so it's like invalidating and confusion to believe shit. Probably why i hate open ends too, fk those tropes too. I'm genuinely crashing out.
