FMA is Hiromu Arakawa's, this text sets after chapter 102 so major spoilers inside, and as I'm French my English isn't very good, so my deepest apologizes for the numerous mistakes here !
"Roy."
A whisper. Relief, denial, sorrow, love.
His light in this deep darkness that will be forever his.
Foolishly, he notices she didn't called him "Colonel". His environment is changing drastically, too fast, but he'll cope with it. Because she will never allow him to break down.
"Hey", he only says.
For the first time in his life she's around and he can't tell where exactly, and he hates it. And he hates himself. He could have avoid her wound, her worrying, her almost dying, and even what happened to him if only he had--
"I'm here", she murmurs again.
She is lost, her hand is shaking when she takes his, but the fresh contact calms them down as he intertwines his fingers with hers. He can only guess she has knelt next to him, once again this day - but it seems it has been years since she stopped him when he lost control with Envy.
"You've always been."
It's a simple statement but it claims everything he has realized during a few hours. Life isn't life if Riza Hawkeye isn't besides him (and not behind, no, he won't accept it anymore) and he can only pray (if there is a god or whatever else to pray) or hope (because this fucking hope mustn't die, never) she'll stay because he just cannot imagine another way.
Her grip tightens on his hand.
" I wasn't. If I had been there when they--"
She cannot go further - and in fact he wasn't going to let her continue. Right now he wishes he could look at her straight in the eyes just one last time - he would give up almost everything he has left just to watch her and tell her, in their usual way, their unspoken conversations, that it's not her fault, that it's just a stupid irony. But he's not good with words when it comes to her and so he holds her in his arms - it's the only solution he found, with this one:
" Lieutenant Hawkeye you are not receiving permission to even think about feeling guilty and I swear this is the last order I'll ever give you."
"Yes Sir", she manages to say with a strange noise.
It takes him a few seconds to understand and his heart breaks agains.
" You're crying."
" 'Am not."
" You are terrible liar, Riza."
This time it sounds more like a chuckle. A desperate one, but a chuckle and he loves this song. Briefly he thinks he'd like to hear it again, and again.
" I am so sorry. "
He can feel her chaotic, erratic breath on his skin - but she breathes and this can be called a little miracle after what they've been through - and her hair tickling his neck - he knows one of the colors he'll miss the most is golden. He can smell her blood, her sweat, and her indescribable little scent of flowers and spices - he swears he'll discover the components of this association and they're no alchemy here. And as he kisses her cheek, to reassure her and maybe, maybe because of something else, he can taste the salt of her skin but maybe, maybe it's just his imagination.
He is blind.
It's maybe not the case right now, but he permits himself to think that everything will be fine.
Because Roy Mustang has four more senses and Riza Hawkeye in his arms.
And nothing else matters.
