Sacrifices (Edward elric x reader)

You fall to the ground, unconscious.
Ed's grin turns down and his eyes widen in horror. A bright yellow light fills the room. He traces the thick black vine that reached out from the machine into your heart. Ed's knees gives up from under him.Al rushes in. "Brother, what's-"ed turns to Al, tears and desperation filling his eyes. "She's gone, Al. She's gone. And it's all my fault!"
Al's eyes widen as he stares at the figure behind his brother. Your body was vaporizing slowly. Al points towards you, shaking.
The yellow light swallows your body, along with the vine and Ed's machine.
Ed turns and hangs his head as everything falls silent. Al stands there wordlessly.
Ed blinks away his tears, determination set in his eyes."She's gone, Al, but I won't allow that. It's not a fair equivalent exchange." Ed looks up at Al.
"We're going to bring her back."

-----------------------------------------------------------------------------------------------------------------------Something weird is up. Your powerful alchemy powers were admired all through the land, and yet no one seems to know what alchemy is. That is, until you meet Edward Elric and his brother, Alphonse Elric. The two are fascinated yet understanding of your powers, and Ed is able to teach you some alchemy, though he won't tell you how he knows. Through many hardships with the Elric brothers, you begin to grow close to them, and even start to fall for Al, but he doesn't feel the same. Ed, though, falls for you, and you couldn't help but feel bad. You don't realize how you feel about him. That is, until Ed sacrifices the most important thing to him to be able to keep you by his side.
