Okay, I should probably clarify what has happened in chapters 9 & 10.
I realize that I didn't go into detail and express better what Asami was thinking aan experiencing. No, the rape wasn't necessary, and it wasn't wise of me to use it when I have a mental block on the topic. Not to mention that I don't know who of my readers have triggers and can't handle that kind of thing. I expressed as much as I could without bringing up anything that I, and anyone else, couldn't handle. I still wanted it to happen. It doesn't have to be necessary to be written. That's like asking if this story is necessary (in my opinion), to which I'd also say no. It's just a story that I wanted to share like every writer on this site. We don't have to write, and we're not forced to write. So no, it's not necessary.
I am not labeling Asami as a weak omega, nor am I labeling Korra the hero of the story. We are only halfway through the story, if not a little over. Just because someone is raped, that doesn't make them weak. While I will explore Asami's PTSD, because she's definitely not fine, it will not be the main focus of the story. She is strong enough to brush off what happened to her because she was more concerned about Korra. She didn't have time to self-loathe, or wrap herself up in her blanket and cry herself to sleep because her mate needed help. So she pulled herself together long enough to put on a brave face and help Korra with her injuries.
Who is stronger in that situation? It works like depression. Just because they have a smile that doesn't mean they're okay. I know what I'm writing and I know how I'm writing it. There's a reason why, as you guys will see in the remaining chapters.
These are just my views, my explanations, and my reasons. It's not an attack, either, but I decided i needed to clarify those things.
Thank you for reading and (hopefully) understanding.
