The Best Type of Transformation

AU: This is slash. Severus/Harry. Planning on this being a long story I hope. Anyone who has read anything by me will know I'm really rubbish at updating and I want to change that I have like 50 unfinished stories on my computer and I will hopefully be publishing them but I want to start with this one. A chapter a week and I give anyone who reads this who wants me to continue to write a comment yelling at me if I don't update. I beg you do it. This story will show Severus and Harry developing their relationship and falling in love. There will obviously be some bumps along the way. I have a rough plot worked out but if anyone has any ideas please tell me. I really hope you like it! I'll shut up now. May be some inaccuracies with some things like I know Severus probably never actually met Gellert Grindelwald but this is a fictional world we can imagine. Okay I really will shut up now bye!

It was just one month after the war when Severus and Harry realised that they didn't have to hate each other anymore and two months when they realised that they didn't want to. They had been getting on better to say the least. Harry no longer purposefully tried to wind Severus up and Severus no longer took house points from him for things like breathing to loudly. It had been hard to get used to but now they actually enjoyed each other's company they would sometimes meet up to talk. Of course Harry had wanted to understand more. He may have been a key part of this war but there was still things that he needed to understand. Things that had been kept from him.

"So you loved my mother?" Harry asked, they had avoided this one topic but now Harry wanted to talk about it.

"Yes" Severus answered not breaking eye contact with the younger wizard.

"And that's why you hated me cause I reminded you of my dad, who took her away" Harry said. He had not meant it as a question he had guessed this.

"No of course not Potter I am not that petty as to hate someone because there father had been a troublemaking buffoon" Severus said rolling his eyes at Harry. "I had to hate you it was part of my role as spy if I had been all smiles and giggling then something would have looked odd" Harry snorted of the idea of his seemingly cold hearted potions master being all smiles and giggles.

"That can't just have been it though you were cold to everyone but you particularly hated me".

"You look like your mother" Snape said, staring into the green orbs of the boy "And it used to kill me slightly to look at you when you look so similar to her".

"Used to?" Harry asked.

Severus nodded, "I'm used to it now I suppose it doesn't hurt to look at you. I don't feel that anymore". This did not mean he felt nothing though. For some reason Severus felt something when looking at his student but he wasn't sure what yet and he didn't really want to think about it too deeply so he did not mention it.

It was the summer holidays at the moment and most of the order had stayed at the castle for this time. It felt like a good way to move on to spend the summer rebuilding Hogwarts to its former glory. They were determined to reopen in September under the supervision of Severus as headmaster. This was if they had any students back in September. The students had not been here for the battle of course but they had heard about everything and most parents were naturally quite scared. It was to be Harry's last year at Hogwarts and he intended to make the most of it with seeing nowhere to go afterwards he had no family to speak of and his best friends were presumably to start a life together. Ron was still completely shaken by his elder brother's death and had as a result not yet returned to Hogwarts from the Burrow along with Hermione. They spoke often but Ron was not the same. No one was really. That's why Harry felt so motivated to get Hogwarts back. He wanted his home back with all his family around him. He was currently working on Dumbledore's office with Severus they had decided to go through and make it an office suitable for a new Headmaster. It was a late afternoon on a Friday they had fixed pretty much everything but the office now and Severus was just returning to help Harry sift through some of Dumbledore's belongings. When he walked in he saw Harry sitting in the headmasters chair with letters around him and basically crying at one letter in particular.

"What are you looking at?" Severus said making Harry jump.

"Oh um just some letters between Dumbledore and someone" Harry said tripping over his words but clearly wanting to be left to keep on reading.

"Dumbledore and who?" Severus said pressing the subject

Harry sighed "Dumbledore and Gellert Grindelwald".

"Harry…" Severus said

"I know I probably shouldn't be reading them but their just so sad. He loved him so much and it just was never returned".

"It was returned, I can assure you"

"How do you know?"

"I met him" Severus admitted "and he said that that was his only regret in life, that he put his crazy ideas before the needs of someone he loved"

"Did you tell Dumbledore that?"

"What would have been the point, Albus could have never had a happy life with him, he was a criminal Harry" Severus said appealing for understanding. Harry nodded sadly "What did you find anyway?"

"Dumbledore's final letter to him"

"Let me see…"

Severus read over it.

August 21st 1938

Gellert

I am writing to you today because without stating this I will never be able to move on. I am no longer blinded by my love for you. Your cause is not something I can support. You had me fooled into thinking that I could change you. That if I loved you enough you would move on from this. I see now that is impossible. I loved you. I do love you. But now it's time I loved myself more. I cannot remain in this relationship. Do not think ill of me. I tried, I really did. You're a fickle man.

It is not only down to your ambitions that I must cut our ties. Your are a homosexual. As am I. But I cannot be in a relationship with someone who will not accept me or themselves. It hurts. I hope you find happiness and acceptance. I can see the path you are going down and I refuse to lead it with you. I implore you to stop before you are in a web that you cannot escape. Despite all this I must admit there is not a day that I will not pray you will change and lead a happy life with me. I do not expect my prayers to come true but there will always be that hope.

Once yours,

Albus Dumbledore,

Transfiguration Teacher, Hogwarts School of Witch Craft and Wizardry

"That was when he started teaching here, when did they meet?"

"When they were sixteen that was in 1899" Severus says

"He loved him for forty years" Harry said.

"Harry he loved him for a lot longer than that" Severus said sadly.

"Have you ever known a love like that?" Harry said awestruck by this side of his headmaster that he had never seen before.

"Not yet…" Severus said picking up the letters and moving away from Harry. Harry watched as Severus walked away. Harry hoped he found a love like Dumbledore's. He hoped that his love would feel the same. Little did he know his love was closer then he may realize and he would most definitely feel the same.

Hope you enjoyed it. Follow the story if you did so you can see when I update it. And leave me any thoughts you have be nice but constructive criticism will always be welcome!
