I love "i would kill for you" ship dynamics but what about "i would stop killing" ship dynamic??
I would lay down my sword for you. I would change my nature and go against everything i've known. I would resist the easy way out of solving my problems. I would give up the adrenaline of battle to stay by your side and make tea instead. I'm not sure I know who I am without a weapon in my hand because I've had to fight for so long but for you I'm willing to try and figure this out.
It must be hard. To put down your weapon that's protected you for so long. It's allowed you to stay alive it's kept you from getting hurt--physically and mentally. Because you've never had to worry about a real relationship if you think you'll be dead at the next battle. And you feel naked without it and it feels like you're ripping off an extension of yourself. Are you even whole without it? Are you worthy of being loved if you can't prove it by risking your life? And yet they've found someone who's asking them for something much harder than dying in battle on their behalf. They've found someone who wants them to live. And that's much more terrifying.
My least favourite type of internet person is the person who claims fanfic is over thousands of years old or whatever. I understand we like to joke but fanfiction is fundamentally tied to fandom culture and is a very specific way of engaging with media. Religious texts based off other religious texts is not fanfiction and it is worrying the only way you can justify your interest is by comparing the two. I promise you you don't have to reinvent the wheel to write fanfic you can just do that but we don't have to say "Shakespeare wrote fanfiction about Richard III", there was not a Richard III fandom in 1592, that was called the divine right of kings.
