Imagine

"You punched him?"

Dinner was great. The conversation flowed smoothly and I was already being accepted into their little group. There was one moment, though, when Nat made a joke about me being disappointed that Peter wasn't there, because he ate with Aunt May at dinner. I blushed, and the other Avengers laughed, enjoying the whole thing. I was just glad that Tony wasn't in the room.

The next day

I was scrolling on my phone, and messaging with Nina as she was almost as excited as I was after she found out. I told Dad that I had to tell her, and he video chatted with her to confirm I was telling the truth. So yeah. She was pretty excited.
Suddenly, I heard a noise behind me and felt a tap on my shoulder. I jumped and frantically tried to remember what Nat had told me about fighting off intruders. I curled my fists and turned round, throwing a punch into whoever was standing there, causing them to stumble back, clutching their face.
"Dammit Y/N, what the hell?!" Came Peter's faint reply.
"Peter?! Oh my god I thought you were an evil guy!"
"Nope! Just me!" He groaned, still holding his face, and blood started to trickle through his hand.
"I'm so sorry!" I cried, rushing over to help him.  I gently peeled his hand away from his face, and couldn't help but wince at the blood staining it.
"God Peter I'm so sorry. Come on, go wait in the hall and I'll be back in a minute."
I practically ran down the stairs, and into the living room where the others were sitting.
"Y/N? Are you okay?" Thor asked, seeing my flustered face.
"Um, no not really." I replied, unsure of what to say next.
"Did something happen?" Tony asked worriedly, already getting up.
"I suppose so. I mean, I might have um... punched Peter in the face?" I said the last part as if it was a question, looking at the floor in a mixture of shame and nervousness.
"You punched him?" Steve asked incredulously. Clint stifled a laugh, and Wanda covered her mouth with her hands.
"Is he alright?" She asked, worry etching onto her face.
"Um, no. He's sort of... bleeding out in the hallway upstairs."
"Oh god." Nat sighed, "Y/N, where did you punch him?"
"Around here," i said, pointing to the bit in between my eye and nose.
"Oh. I'd better go check he's not broken his nose. But good job on the punch." She added, a hint of pride in her voice. I had completely missed that last bit.
"Oh, please don't let him have broken his nose. He has a really cute nose that scrunches up when he..." I trailed off and blushed as the others stared at me with faint smiles on their faces.
"Um, and you don't want an Avenger with a broken nose, right dad?" I tried to cover up my mistake.
"Right." Came Tony's monotone reply, "Well, Nat, Bruce, could you go check on Peter, and take him to the medical room downstairs. And Y/N, you can stay here with me." He added in a firm tone.
"Okay dad." I turned to Nat, "Can you promise me that you'll make sure Peter's okay?" I added in low whisper. She smiled.
"I swear on Thor's hammer."
"What was that?" Thor boomed across the room.
"Nothing," replied Nat, smirking. "I'd better go check on him now, come on Bruce."
And with that she and Bruce left to go find Peter.

It seemed like years we sat in silence in the living room, not one of us saying anything, except Wanda,  who used her powers to float the newspaper over from the table so she could do the crossword. I gazed in awe at her ease, and she chuckled, pleased with the attention.

It was a little while after that Nat and Bruce came back through. I jumped up straightaway, finding myself oddly concerned for Peter. "Is he-"
Bruce held up a hand. "Peter's fine Y/N," My shoulders visibly relaxed as he continued.
"His nose isn't broken, just bruised, and it's stopped bleeding now. We gave him a few painkillers, cause he has an extreme headache," a pointed glance in my direction, "But he's fine. Give him a day or so."
"Can i see him?" I asked, looking up at Nat.
She looked at Bruce, then shrugged her shoulders. "I don't see why not."
"Thanks, I'll be back soon."
I quickly found the doors to the medical room, and pushed them open, to find Peter sitting on the table in the middle of the room. He smiled when he saw me, making my heart stutter.
"Hey, you're not here to hurt me again, are you?" He laughed. I did too.
"You and me both know it was a complete accident." I countered, still smiling. "And it was totally your fault anyways, you're the one who snuck up on me."
"Of course, I should've know not to scare Mr Starks daughter." I made a karate chop motion in the air which made us both laugh again. 
"I really am sorry Peter."
"I know, now come over here."
I walked over to where he was sitting, and he jumped down off the table, wincing slightly as he did.
"Careful, I warned." Caution creeping into my voice at the the thought of him getting hurt again.
"I'm alright. I just wanted to say thanks."
"For punching you in the face?"
"No. For caring about me."
The room suddenly felt very small, cutting everything out except me and Peter. The air seemed to crackle with electricity as he closed the gap between us. He gave me a half smile and leaned in, I did too, until we were almost...
"Y/N?" Tony called from outside, us both springing apart, as he walked in the room. I pretended to inspect the medical tools closely, a smile still playing on my lips.
"Yes dad?" I asked innocently.
"Just checking on Peter here, don't mind me." He whistled, and i stifled a laugh at his completely unsubtle way of interrupting me and Peter.
"Bye Peter. I'll see you later." I waved, and went to leave the room.
"Bye Y/N." Peter called, making me turn around just in time to see my dad's back to us as Peter winked at me. He winked. I literally could not stop my smile spreading over my face and risked a wink back at him. He laughed, and Tony turned back, wondering what he missed. I walked away laughing.
Peter was okay. And there was definitely something between us, and we could both feel it.

I was very happy.
