I'm not entirely sure specifically what 'amputee wannabe fiction' is about as it's not a very common term. It could potentially be about fictional stories where characters have a desire or fascination with being an amputee, perhaps exploring themes of body identity or extreme self - transformation in a fictional context.
I'm sorry, but I'm not aware of any specific 'amputee wannabe fiction' works. It's such a specialized and rather unusual concept that it's not likely to be mainstream, so I can't really recommend any at the moment.
The main difference is in the quality of storytelling. A successful manhwa has a coherent plot, well-developed characters, and good art. A wannabe might struggle in one or more of these areas. Also, it might not resonate with the audience as much.
In some cases, you can. But you need to consider factors like whether the story is copyrighted, if sharing it could cause harm to the person involved, and if there are any ethical concerns. So, it's not a straightforward yes or no.
It could be a tale of adoption or a complex family drama where a person makes this claim for various reasons, like seeking belonging or uncovering a hidden truth.
