Disclaimer: Sadly I don't own Harry Potter, it's all JK Rowling's work.

When Harry woke the next day he looked at the time which was 6am and got showered and dressed in plain muggle clothes which were becoming quite a fashion in Wizarding Britain, Harry then apparated to The Ministry of Magic and went to the Ministers office, he knocked on the door and entered when he was told.

"Minister- "

"Harry how many times do I need to tell you? Please call me Kingsley."

"Sorry. Kingsley I am here to hand in my resignation I don't want to be an Auror anymore."

Harry said as he passed his resignation over to Kingsley

"It is a shame that you are leaving the Auror department, I don't think we've had anyone as good as you for a couple of decades but I understand. Please correct me if I'm wrong but I believe you were pressured into taking this job." Kingsley said from his seat behind his desk.

"You are correct Kingsley, I didn't want to take this job" Harry said as he collapsed into the chair in front of the desk, looking at Kingsley over the desk he continued "In all honesty I just wanted to have a quiet job or at least something where I won't be in constant danger."
"I was quite shocked when I saw your name on the list of applicants, though you got the job quickly without any training many were very upset about that, but I was shocked because I believed that after all the shit you went through with Voldemort, I take it Ginny pressured you into it."
"Yes she did." Harry said sadly as he looked down at his shoes, he started to get up when Kingsley stopped him,

"Harry, I know that Minerva McGonagall is in need of a Defence Against the Dark Arts professor and you fit all the requirements. Hogwarts is almost complete just a few parts need to be cleaned up and fixed, she and the other professors are currently living in their own quarters there to start sorting the next year out, well if you want I can floo Minerva and tell her you are looking for a job."

"Sure Kingsley I guess teaching could be a good job, if you floo her tell her I will be in her office around 12pm, I will be going to Hogwarts to see how much I can help with." Harry said before apparating to Hogwarts.

Harry had about 5 hours before he had to meet Minerva, so he along with many others got to work on fixing the courtyard (where Voldemort died) and clearing all the rubble that was there. After 3 hours the courtyard was fixed and tidied. The group of helpers all separated into groups of no more than 5 and all went separate ways in the castle to access and make sure everything was perfectly stable and fixed.

Harry continued to wander the castle when the rest of his group headed back to the courtyard to leave, he walked to the Gryffindor common room and was surprised to see that the fat lady was still there,

"Can I go in?" Harry said

"Fine." She said annoyed as he interrupted her 'singing' if that's what you can call it, the portrait swung open and Harry walked in and laughed to himself

"After the war this place still looks the same." He said to himself before he headed to his old dorm room looking at his old bed he started laughing louder as he read at the foot of the bed, carved into the wooden frame said 'Harry Potter slept here, the next bed Ron Weasley his awesome best friend slept.' It was obvious Ron wrote it.

"Mr Potter" came a voice from the door, startled Harry jumped and had his wand out, after seeing who it was he blushed bright red and put it back in his pocket,

"Sorry Professor."

"Please call me Minerva. Would you like to come to my office to discuss your job here?"

"Yes pro- Minerva"

The two walked into what used to be Dumbledore's office, Minerva walked around the desk and took a seat before gesturing Harry to the seats in front of her

"Mr Potter-"
"Please call me Harry." He interrupted to which the headmistress smiled at,

"Harry, there is one job that hasn't got a professor yet and that is Defence Against the Dark Arts, I believe there is no one who has the same experience as you in this topic, so would you take this job?"

"Yes, I'd love to" Harry paused when he saw an oddly similar twinkle in her eyes which reminded him of Dumbledore "What else is there?" He asked knowing there was more

"Well Harry as you know I am the headmistress and I am not allowed to be a head of house either, so would you like to be the head of Gryffindor?"
"I don't have a choice do I?" He chuckled

"Not really."

"Alright. Minerva are you sure you're not a Slytherin?"

"You wound me Harry, how could you think such a thing? I was most definitely a lioness" Minerva said jokingly as she stood up and placed a hand over her heart

"Ah but Minerva" He said as he stood up too "Surely you know that no one expects to find a snake in a lion's den."

"Very true." She laughed before holding her hand out for Harry to shake, which he did

"So I will give you a list of rules and some guidance tips, if you would like I can go over your first few lesson plans to make sure they are alright. I will need you to be in school no later than the 27th August so you have a week but you can always come here earlier, when you do bring anything you need from home and I shall show you your quarters, office and classroom."
"Thank you Minerva and I think it would be a good idea to have you look over my lesson plan, I will probably arrive sooner but it all depends." Harry said and then started to head to the door.

"Harry." She called causing him to stop and look at her she smiled gently and said "It's good to have you back."

"It's good to be back." He replied gently with a smile before walking to the courtyard and apparating to his house which was left by his parents, it was a big house but not a mansion, he had many houses and estates but he went for the smallest even though it was big because all the personal belongings of his mother and father were kept there along with the items that survived at the Potter's cottage at Godric's Hollow. Getting home he collapsed on the couch out of exhaustion.
