Warning: this is disgustingly sweet and you will probably die for the amount of adorableness in it... Just in case any of you don't like romance

The previously bad day had turned out to be one of the best days of his life.

Who cared if Flash was an asshole, or if he had been hurt, or if his bag was stolen, or if Happy didn't listen to him, or of the security guard was kinda mean?

At the end of the day, Peter didn't care about Flash, he had better friends and people who cared for him surrounding him. He had been hurt, but his family was there to take care of it and make sure he would be alright. His bag went missing, but that really wasn't a problem when your mentor (aka dad) was a billionaire that loved to spoil you. And what if Happy didn't listen to him? Peter had friends and family that loved him and were always happy to give some of their time to listen to him. And about the security guard... Peter couldn't blame him; it was his job after all.

That day, his family had pampered him and given him more attention than usual, which was saying a lot. He had even gotten a hug from Tony!

But the real highlight of the day was another. His name? Harley Keener.

That man looked like he had been sculpted by Greek gods themselves from Peter's perspective, and he often found himself thinking of him in ways that couldn't be justified by friendship.

Peter had fallen for Harley. Hard.

But god if he had reasons to. The boy was brilliant, an absolute genius with an unmatched creativity (Potato gun? Ring any bell?). Peter could stare at him for hours on end and never get bored, finding a new detail about him to admire each time he did.

And Harley wasn't any different.

To his eyes, Peter was a literal angel: the most selfless and adorable person he had ever met. When he smiled or laughed, Harley had to do a conscious effort to stop himself from staring and smiling like an idiot, but he was tempted every time.

Harley could swear he melted every time Peter carelessly gifted him a look as if it were nothing, when it caused a zoo to appear inside the stomach of the boy from Tennessee. And when Peter talked science... Harley was fascinated by it, but he found it hard to pay attention to the words leaving Peter's mouth when he sounded so excited and looked as happy as he did.

But neither of them knew about the other's feelings.

"I swear to god, I saw the sun hiding in shame after seeing how bright Peter was."

"That's called nighttime, Harley," Tony said with a sigh. The boy payed him no mind.

"And have you heard him laugh? I didn't know sounds could be addictive until now."

"Harls, I love you but please stop," Tony said in tiredness, rubbing his eye.

The boy pouted. "You're not fun."

•××ו

"Is it just me or is Harley the most intelligent person alive?" Peter said in a low voice while the boy he spoke about worked in the lab.

"I take offense in that," Tony said as he stopped working.

Peter's eyes left the blonde's busy hands for a few seconds, and he looked at his mentor as if he had forgotten he was there in the first place.

"Uhh... Sorry, dad."

Peter blushed. He had not only spoken about Harley to Tony- he had also called him dad!

"Sorry! I didn't mean to say that, I swear!"

Tony stopped working once again. "You're not allowed to call me anything else from now on," he stated with finality.

"But, Mr. Stark-"

"Uh-uh-uh," he interrupted the teen. "If you call me that once more, you're grounded."

Peter smiled a little. "Okay, dad."

At the background, Harley could be seen fanboying silently in the floor.

"I swear he can't be any cuter."

Pause.

"Harley, I still have super hearing."

"I know."

Peter blushed again.

•××ו

"He's so oblivious, it's adorable," Harley told Tony as they revised some blueprints. Peter was inside the lab too, but he was on his own.

"Harley."

"Have you seen him, Tony?"

"Harley."

"He looks like he just fell from Heaven."

"Harley, stop."

But Peter, from the other side of the room, was confused. "Did you just call me Satan?"

"I-"

"Oblivious, Tony, I told you."

•××ו

"He's so beautiful I swear-"

"Harley, if you aren't going to ask him out and tell all these things to him, stop." Tony was tired, so tired.

"What? Why would I do that?" Harley asked him. He seemed almost alarmed. "He doesn't like me, I'd just ruin everything!"

Tony tried not to facepalm.

"What did you say about him being oblivious, sorry?"

Harley brightened up instantly. "Yeah, that he's so cute-"

Tony groaned.

Tony sat in the head of the table in a conference room, all the other Avengers surrounding him and looking at him in confusion.

The billionaire had his palms together, with his index fingers extended over his mouth. He seemed to be waiting for something.

"Tony, what's going on?" Steve asked for the group. The billionaire held up one hand to shush him and waited a few more seconds.

Friday's voice came out of the speakers, startling everyone but her creator. "Peter is now completely out of hearing range, boss."

"Thank you, darling," Tony said to his AI before standing up and finally addressing his teammates. "We're here to set Harley and Peter up. They're disgustingly in love with each other and none of them realizes their feelings are reciprocated. I swear to god they're driving me insane." Tony plopped back down on his chair, as if a huge weight had been lifted from his shoulders at the prospect of getting a solution.

The Avengers looked at each other and a few nodded in agreement.

Natasha stood up with a smirk gracing her lips. "Let's do it."

Clint started shouting quickly. "No! He's a baby! We can't do that- Author don't you dare cut the scene before I finish-"

•××ו :)

"Everyone remembers their part?" Tony asked them all in a whisper as the elevator doors opened to show two happy teenagers who came from the lab.

A couple "yeah" were heard from the group, but they all shut up quickly so they could put their plan into action.

"Hi, Mr. St-" Peter cut himself off. "Sorry. Hi, dad, everyone!"

Harley smiled. "Old man, people I barely know," was his greeting.

The Avengers tried to stay serious as Sam stood up and headed to the fridge, opening and faking surprise, taking a hand to his mouth. "There's no more milk!"

Vision stood up too and went to the cupboard. "We are also lacking cereal," he deadpanned.

Wanda looked over her boyfriend's shoulder and opened her eyes just a little too much. "No bread either."

Bruce took a hand to his chin in an 'I'm thinking' fashion. "What could we do to solve this?" he asked with exaggerated worry.

"I have an idea!" Tony piped in. "Peter and Harley could go buy some!"

"Yes! Together!" Steve exclaimed.

"And they could also buy everything in this extremely long list that I definitely haven't been hiding!" Bucky said.

Harley blinked twice in confusion. Peter tilted his head to the side.

"What?" they both asked.

Natasha suddenly stood up, seemingly done with life, and shoved the list into the spider-teen's hand. "We need you both to go buy this, please."

Harley looked at Peter, who shrugged. "Sure."

Then they left through the elevator they had just come out from, and the red-haired woman turned to his teammates. "You're all fucking idiots."

"Language!" everyone but Cap instantly said. The latter only sighed in defeat.

Later that day, the father-son duo was back in the lab.

"How was your date with Harley?" Tony asked.

Peter choked. "What?"

"Your date," Tony said slower.

"We just went to the store. As friends. We're not dating. He doesn't like me."

The billionaire felt the temptation to slam his head in his desk, but refrained from doing so.

That moment was conveniently the one in which Harley entered the lab.

"Oh, would you look at the time!" Tony all of a sudden said while looking at his wrist and standing up. "I gotta go!"

"Tony," Harley started, "you don't have a watch."

"I have to go to work regardless!"

"Dad, you work here. In the lab. For SI."

Tony paused.

"Sorry, kids, I'm late already; no time to discuss!" And he left.

Both teens looked at each other with the same expression on their faces. "What the hell?"

•××ו

One day later, the trio was back in the lab. Once again, Harley and Tony were working together while Peter worked on his own.

The spider-boy suddenly sighed and left what he was doing, approaching both of the other people in the lab.

Tony watched in happiness and relief as Peter wrapped his arms around Harley's waist from behind and rested his face in the crook of his neck.

"Yes! You're finally dating!"

Both teenagers froze. "We're not dating, old man. Why would you say that?"

Tony's eyes filled with dread. He'd have to deal with it for even longer? He wasn't sure he would be able to.

"You- you're hugging!" Tony was almost desperate at this point.

Harley and Peter looked at each other then back at Tony.

It was Peter who spoke. "We just talked about toxic masculinity and then this happened-"

Tony was about to scream.

•××ו

"Hi, dad!" Peter said two days later as he entered the living room next to Harley.

"Hey, kiddos. Everything alright?"

"Yeah, we just came back from having lunch!"

Tony started preparing himself mentally for the frustration that was sure to come.

"Oh, you went out for lunch? How nice!" he said. "Just a good lunch as friends..." Tony could swear it had reached the point of trauma. If it hadn't, it was close.

The boy from Tennessee smiled. "Actually, it was a date." He grabbed Peter's hand softly.

Tony choked.
