I got this idea from ISBtheepic on AO3, I had the idea a while ago myself as well but seeing this account starting to write it, It gave me the push to make one too. Civil War is after homecoming in this one, and Tony doesn't know Peter.

This friday wasn't Peter's day. He woke up late with an unpleasant feeling in the base of his neck. A shiver worked through his spine and he was on high alert. Then he had to mis breakfast because he forgot to do grocery shopping yesterday so al the way to school, his stomach was groaning. Ned saw him coming from far and noticed that it was a bad day.
"Spidey senses tinteling?" He had asked. Peter had groaned and had answered that they wouldn't stop.
Classes were more boring as always. Flash was insulting him more then ever, he was only lucky that Harry wasn't here.

Harry Osborn had once been a great friend of Peter, once. Now, he enjoyed tormenting Peter with Flash.

"You're coming over to my house after school, right?" Ned asked when lunch finally came. Peter nodded, prodding at his lunch. He had to buy lunch in the cafetaria and it had looked everything except appetizing. Peter decided to eat it anyway because otherwise his fast metabolism would make sure he got weak and sick.
MJ stopped by halfway through lunch to tell them that the decathlon practice was delayed till Monday before walking away again.

And when school finally closed his Spidey senses tingled worse then ever. Ned smiled when they reached his house. He had bought a Lego Millennium Falcon so he was excited to finally begin building it with Peter. Halfway through, the volume of the TV downstairs was turned louder and Ned's mom called them downstairs.
"Something crazy is discovered!" she had yelled. Peter and Ned had looked at each other before dropping everything and sprinting downstairs.

Harry Osborn was on the television together with Tony Stark, Peter's idol, and his father, head of the OsCorps. The journalist looked excited and honored to be there. She looked in the camera.
"People of New York, People of Queens. For one year we have been seeing a masked vigilant save our lives and put his own in danger. For one year, the friendly neighborhood Spiderman has been a part of our society and today we finally get to know the person behind the mask."

Peter, who had been drinking water spit out his water and choked on the water that was left in his throat. Ned's eyes had the size of a dinner plate and his parents looked at the screen thoughtfully. Ned and Peter threw some desperate looks to each other before focusing on the news.

"I know, what a shock right? But our very own Spiderman has been living right under our noses all these years. I won't let you wait any longer, our famous redsuited hero is.." The reporter held her breath a few seconds for the tention. Peter became pale and his eyes darted through the room. "Harry Osborn! Son of the famous Norman Osborn." Harry was waving at the screen full of confidence.

The room was quiet, you could only hear distinct noises from the television. Peter's first reaction was to sigh, relieved that they didn't know it was him until the name shook him awake. Please tell me that was a joke, not Harry. Ned looked at Peter, he looked like he was panicking.
Ned's parents sighed.
"Probably fake news, never trust an Osborn." Ned's father muttered. Peter knew that, after everything, he would never trust an Osborn anymore."

"I always knew my son was a hero, no doubt. And when he told me yesterday, I knew I had to let the world know. We contacted Mr. Stark so he could become my boys teacher and we decided that if he saw that Harry was worth it, Harry would join the avengers and the rivalry between OsCorps and Stark Industries will finally be over!"

Peter looked at the screen like it had sucked his entire life away. That was his dream, to be a protégée of Tony Stark and to one day join the avengers. Ned led Peter to his room where they sat in silence.

"What are we going to do Pete? We have to tell them!" Ned began rambling about different ways to reveal the truth but Peter wasn't listening.

"We're not going to do anything yet." Peter answered. Ned stopped babbling immediately and looked at Peter questioningly.

"I'll play his game for a week or two, if they haven't figured it out till then, I will reveal myself. Not as my identity, but I'll show myself in the same room as him."
Ned nodded thoughtfully.

"I'll trust you on this Peter." He said, before he paled and groaned.

"What?"

"He's going to be unbearable on Monday." Peter groaned to and fell on Ned's bed. His Spidey senses had stopped tinteling a while ago but his anxiety never stopped.

~~

"Hey Kid, excited to go to school?" À voice woke Harry from his sleep. He groaned and woke, the sun shone in his eyes. The memories from the last few days appeared before his eyes and he grinned. Saying that he was Spiderman had been the best decision he had ever made in his entire life. His father had been working with some serums and Harry had found one wich gave you superstrenght for 12 hours, he just had to take a sip everyday and he would be stronger then the normal human, not as strong as the real Spiderman ofcourse but enough to fool everybody. He had told everyone that the sticking to the walls had been a special thing in his gloves so Tony had improved this design and gave him new gloves, gloves that actually sticked to the wall.
The webs had been the only problem, he could figure out how they were designed, and what he had was weak and couldn't even support a cat if needed. But nobody had asked for his webs so he was safe at the moment.

"Not really, I just hope Parker won't show his face." The last part he had mumbled but Tony had heard him anyway.

"Who?"

"Peter Parker, he's..." Harry halted, turning around with a grin, knowing that if he played this correctly  that Peter would be in a shit load of trouble.  "He bullies me. Nobody ever sees it except my friend Flash so nobody knows. But he keeps calling me names and threatening me."
He turned around with fake fear on his face. He saw that Tony looked super angry so inwardly he was celebrating.

"He won't do anything now, now he knows you are Spiderman and if he does anything, I'll go talk to him." Harry inwardly grinned. Jackpot

"Thank you sir." Tony sighed before correcting that it was Tony before walking away.

In school he met up with Flash. He told him how he had tricked Tony into believing that Peter was a bully and that he needed Flash to confirm him.
Flash ofcourse agreed immediately.

Everybody in the halls began talking as soon as they saw Harry. They asked for his autograph and at least 20 girls asked to be his girlfriend. Harry grinned al the way but he was looking for someone in particular. Then Peter showed up, he was talking with Ned about something. When Harry stopped behind Peter the entire hallway seemed to held it's breath.

"Hello, Peter." Harry said mockingly. Peter closed his locker and turned around. He looked bored.
"Oh, hey Harry." He didn't say anything else and just started to walk away. Harry was confused for a moment but followed after him.
"You might want to give up your spot for the competition this Wednesday." Harry said smugly.
"Just beat me in the selections today and you'll have the spot automatically." Peter rolled his eyes.
"But I'm Spiderman, I have to make sure my grades are perfect and this fits perfect."
"But if you're Spiderman you can put your selfish wants aside for the greater good."
Harry was silent for a moment, this was not what he expected.

"Bye Harry, I got class. See you at decathlon." Harry and Flash looked after him dumbfounded and Ned high fived Peter.

At the decathlon pracrice, Harry was nervous. He knew he was smart, but he also knew that the other spots in the team were already filled and he had this one chance to win. But he had to compete against Peter. Then he grinned, he was smarter then Parker after all, otherwise he would threaten Parker with his superstrenght. 
The test was difficult but he did well he thought and he gave his paper before Peter so Peter was probably failing.

After an hour, MJ came back with the results. She grabbed the attention.
"Guys, our final member decided. Peter has a total of 96 points." The Team clapped politely, except for Ned, he was whooping for his best friend.
"And Harry would have had the same, if he didn't miss 3 trick questions. I'm sorry Harry, but Peter is in the team!"

Harry looked shocked, and then started feeling angry.
When Happy picked him up, he didn't even greet him, he rudely ignored every question and he stomped into tower.
Everybody looked shocked at the teen that was supposed to be the friendly neighborhood Spiderman.

Tony looked happy to greet him until he saw Harry's face.
"Kid, what's with the long face?"

Harry turned and was about to rant until he remembered something.
"It's just stupid Parker, he said I was a freak, he became worse."
Tony's eyes flashed in anger.
"Make yourself at home kid, I'll go talk to him." Tony stormed into the elevator and Happy kept his frown until Tony disappeared. Then his smile got wide and he skipped to his room. He didn't see the two eyes watching him.

Peter swingend through the city. His senses tinteling and he was right on time to save an 8 year old child from a car that would have ran her over.
"Thank you." She whispered before running to an angry man. People around him began to cheer and to call Harry's name. Peter fought back the urge to out that he wasn't Harry but he stopped himself. Not yet.

After his patrol, and his call to Ned to tell him what has happened, he changed back into his normal clothes and walked to his home where May would have prepared dinner by now.
He skipped to his apartment and opened his door. But instead of getting a warm welcome, there was a mad Tony Stark sitting in the sofa and a nervous aunt May.
"May, are you alright?" He thought something awful had happened, why else would Tony Stark be here anyway.

"I'm fine Peter." He hugged his aunt. Tony looked surprised at the action, he briefly wondered if this boy could bully someone when he's so worried about his aunt but then he saw Harry's angry face and he scowled again.

"Mr. Stark, what are you doing here?" He turned towards him when he finished hugging his aunt. His eyes full curiosity.
"You know well enough why I'm here." Stark answered harshly. Peter's happy smile turned into a hurt expression before he turned confused.

"What do you mean?" May asked. She looked at her nefew who looked just as confused. Tony sighed seeing that he wasn't going to answer.

"You'll have to stop." He ordered. Still he got only confused looks in return.
"With bullying Harry." There was a few moments of silence before both aunt and nefew shouted their answers.

"You think I/My nefew am/is bullying someone?" Tony wanted to wince because of the death glare od the aunt but he nodded, saying Harry had told him himself.

"Wait," May said, she looked suspicious, "You mean Harry Osborn?" Tony nodded. May got an angry look in her eyes.

"I see he got you winded around his finger. Tell me, why would Peter bully his childhood best friend when they stopped being friends because Harry insulted his parents? Why would Peter be the one that comes home with bruises when he's the one that bullies? No Peter, we're having a conversation about this another time. Why would Peter bully someone who could get him kicked out of school and ruin his future? Tell me."
Tony was silent, Peter looked embarrassed and aunt May was steaming. When she didn't get an answer she sighed and ushered Tony outside.
" Come back when you're ready to apologize. " She screamed while she threw the door shut.
Then she went to Peter and hugged him. They stood there like that for a long time.

As it seemed, Abe was suddenly not able to compete in the competition so Harry was able to go as well. MJ was drilling everybody on the bus and when they finally had a moment peace, Peter looked anxious outside. Ned sat next to him, rambling about the next and final Starwars movie theories and MJ was reading a book about the Afro-American history in America.

Right before the competition the alarms in the building went of and everybody ran outside. Once outside an old man ran towards the building. His bushy white eyebrows were high up and his glasses looked hazy.
"Please, my grandchild is inside." He begged.

The class turned to look at Harry who paled. He thought about the serum he didn't take just today.
"Where are you waiting for? You're Spiderman." someone said urgently. Harry gulped but ran inside.

Peter had already ran of and slipped inside via the back entrance.
A young child was screaming and he ran towards the scream. He saw Harry trying to lift the iron table that blocked the child from escaping.
He pushed Harry aside and lifted the table like it was easy. He picked up the child.

"Hey hey... We're going to bring you to your gramps okay?" he said softly. The girl nodded and clamped around him. Then he turned towards Harry. Harry looked both embarrassed and angry.
Peter smiled softly and passed the girl to Harry. He assured her Harry would get her out while he wouldake sure nobody else was inside. The girl nodded hesitant but klinged to Harry anyway.
Before Harry left he turned to Spiderman.
"Why?" He asked. If he could have seen Peter's face he would have seen a mischievous grin.
"I'm not the one for a spotlight... You have a week."
And then he swingend away and Harry ran outside with the child. Once he left the building, everybody started cheering except Ned and MJ.
They shouted his name and the granddad ran to the child.
"Thank the gods you're safe." He said before hugging her.
"What do you say to the young gent?" He asks.

"You're not my Spiderman." She said and then she pulled her granddad with her saying something about the real Spiderman while the man scolded her for being rude.
Luckily nobody else seemed to have heard the comment.

Peter ran out of the backside of the building right before it collapsed. He breathed in relief before walking towards a closed off empty space. Right when he wanted to remove the suit he heard someone arrive. He turned around and his eyes widened.

"Peter Parker."
