Natasha X Steve Fanfiction (Romanogers) ~It always was you~

I miss you Romanoff

Steve:

It has been now two weeks since we won the fight against Thanos, but we had a really big loss for all of us. Because we lost our Iron Man, Tony Stark and our most talented spy, Natasha Romanoff, who stole my heart. She was my best friend and a little bit more, but unfortunately she didn't knew about my feelings. I'm such an Idiot. I was always convinced that Peggy was my first and last love, but then Natasha came in my life and she changed everything.
Damn I miss her so incredibly much.

On a sunny morning:

I visited Natasha's grave almost every day, I cleaned it and laid fresh flowers down. One day I saw her little sister Yelena Belova, she also stood at her grave and laid flowers.

"Hey Yelena!" I greeted her kindly.
"Steve!" she remarked me and gave me a friendly hug.
"You have laid beautiful flowers! daffodils right?"
"Yes! I think she would have liked them!" she murmured, looking at her name in dismay.
"I miss her so incredibly much, Steve!" she said.
"Me too, but don't worry. Natasha is coming back!" I answered her. I was sure, that I could do it, but I had no idea how.
"What?" She looked at me confused.
"I'll get her back!" I said confidently. I have to get her and Tony back. We wouldn't be Avangers if we didn't make it. Finally, I have to confess my love to Natasha.
"How do you plan that Steve?"
"I'll think of something. I'll get everyone together and we'll have to come up with a plan!"
"Steve. You know that is not possible, right? I wish me so much, that she could be here with us again, but that's impossible!"
"Yelena! Never say that it's impossible!" I answered her and ran back to my bike.
"Wait Steve! How are you going to do that, Steve?" Yelena asked me and ran to me.
"I still have no idea how. Maybe with a machine that travels back in time? I need to talk to Bruce, Sam, Wanda, Clint, Strange. Maybe there is a way!"
"OK! I'll help you. Whatever you need!"
"Agreed! Come with me to headquarters!" I got on my motorcycle and drove off, followed closely by Yelena in her car.

At the Avengers headquarters:

When we were all the Avengers present, even Thor who came in from the Universe. I told everyone about my plan to bring Natasha and Tony back.
"How are we supposed to do that? It's impossible to just go back in time and take people with you!" Thor questioned directly.
"It's not that impossible!" Strange answered us. "I've heard it's possible!"
"In what way?" I asked immediately.
"You can open a portal once and it lasts for 30 minutes, so you can go back in time! It works similar to the Infinity Stones," Strange said.
"I don't think it's that easy. Natasha and Tony are dead. You can't change the past!" Clint shook his head.
"Stop talking such nonsense! It's your fault, that my sister is dead!" Yelena yelled at him and attacked Clint.
"How often should I explain you this? Your sister sacrificed herself, so that we can all be here and can live!" Clint said coldly.
"Shut up your mouth!!" Yelena cursed in Russian and pressed a knife to his throat. "You can be glad I don't kill you!"
"Yelena! Stop it!" I immediately pulled Yelena away from Clint.
"I think we should vote as a team. If we are all for it, I would also like my brother Pietro to come back too!" said Wanda.
"Loki should go back too!" Thor prompts.
"We were only talking about Natasha and Tony, maybe Pietro too, but Loki? Loki has done so much damage!" I said.
"He's my brother, Rogers! Either he comes with us or no one!", yelled Thor.
"Alright!" I agreed, although I didn't agree, but this is about Natasha and Tony. We voted and we all agreed that we wanted to try it.
"Let's get to work then! I'll bring Natasha and Tony back!"
"Are you sure, that you can, Captain? Not that you burn away with your lost flame named Peggy! This is about Natasha, Tony and my brother!" Thor said and grinned.
"Do not worry! I'll get them both back. You have to get your brother back and Wanda hers. We don't have that much time either!" I argued.
"Deal!" said Wanda and Thor.
