[HP] Dearest Enemy

Tom glanced at Harry, who was sitting opposite him, feeling a little uncomfortable.Throughout the holiday, his attitude towards Harry was neither cold nor indifferent, and he would not speak if he could not speak.Tom didn't tell Harry that he worked in Knockturn Alley, after all, it was not a place for wizards his age, he only said that he worked in an herb shop in Diagon Alley.Fortunately, Harry is also quite busy this holiday, almost always preparing the lesson plans of Defense Against the Dark Arts and sorting out the things left before.As Tom had expected, Harry had brought all his research materials with him to school, leaving little at home.

Maybe it's because I'm going to school with Harry for the first time, so I'm so nervous, the black-eyed boy thought.Tom wasn't worried that he wouldn't be able to find an empty cubicle. The first few boxes were all Slytherin's territory, and one of them was Tom's exclusive box, which was well known in Slytherin.

"Hey Tom, how was your holiday?"

Alphabet Black came in dragging the box as usual, the only one entitled to the same treatment as Tom.Seeing an adult suddenly appearing in the compartment, Alphat was slightly taken aback.

"Hello, Al." Tom introduced his guardian to his friend, "This is Harry Potter. Harry took over from Professor Mellorth as the teacher of Defense Against the Dark Arts. Harry, this is my roommate Alpha Ter Black."

"You are Mr. Potter!" Alfred looked at Harry who had stood up in surprise and curiosity, and stretched out his hand to Harry, "Tom often talks about you."

"Hello, Alphard." Harry shook the boy's hand, feeling as if he saw a shrunken version of Sirius.Harry suddenly remembered that one morning he was standing in the living room of No. 12 Grimmauld Place, looking at a moth-eaten yellow tapestry with Sirius who looked melancholy beside him.

"...my uncle Alfart left me a considerable amount of gold - he himself was purged from here, probably because of this..."

"You can call me Harry, Alphard." Harry smiled at the boy.

"That's impossible." Tom glanced at his friend, looked at the man sitting opposite him, and said calmly, "Harry is now a teacher at the school, we should call him Professor Potter."

Harry looked from Alphard's face to Tom's.Tom looked at him briefly for a second, and threw a small package into Alfart's hand: "What you want."

"Oh, thank you." Alphard looked cautiously at Tom, then at Harry.Harry stared at Tom for a moment, then finally looked away, chatting with Alfred.

Not long after the train started, Tom said he was going to find some friends and left the compartment.Alphater was hesitant to go out with him. Professor Porter was very easy to get close to, but his relationship with Tom didn't seem to be very good.It was no wonder that Tom was angry. His only relative had ignored him for two whole years, and even Alfred would not forgive him easily.

Just when Alfred was about to sneak out with Tom, Harry spoke.

"Alphat."

"Professor Potter?" Al looked at Harry with big eyes with long eyelashes.

"Did Tom... bully you at school?" Harry asked.

"Bullying me?" Alfred was a little surprised, shaking his head, "Tom always protects me. In the first grade, Billy Weasley from Gryffindor often bullied me, and every time Tom helped me put him down." Chasing away... Tom has good grades and often helps me with my homework. Tom never bullies me, and he collects plugs for me..."

Harry had a weird look on his face, reassured by Arffat's narration.Tom obviously took good care of his roommate, and Harry heard a long list of Tom's heroic deeds from the teenager.Maybe he was really overthinking, Tom was not the lonely Voldemort, he had at least Alfred as a friend.

Harry and Alfred chatted all morning.Tom didn't go back to the cubicle until the small cart that sold things at noon came.

"Tom!" Alfred happily pulled Tom to sit down, "You came back too late, Harry told me a lot of things I didn't know..."

Tom glanced at his chattering buddy, then at Harry.The guy had said something to Al, and within a few hours Al was calling him by his Christian name.

"Tom, your sandwich." Harry took out the prepared food and handed one of them to Tom.Tom frowned. He used to buy some snacks on the train to satisfy his hunger, and his helpers would bring him something to eat. He didn't need to make any preparations himself.But Alfart was watching, and Tom had to take the sandwich Harry had prepared for him, and thanked him in a low voice.Noticing that Harry was eating a tuna sandwich and giving himself a turkey sandwich, Tom pursed his lips, not expecting Harry to remember his favorite taste.

Alphard looked at the expressionless Tom with some concern, for fear that he would not be able to eat it, but Tom took a bite naturally and chatted with Harry casually.

It seems that I was thinking too much, Alphater thought, the relationship between the two of them should not be as bad as I thought.

No one bothered them all afternoon, and Arffate guessed Tom wouldn't let them come to their cubicle.Fortunately, Harry has a lot of travel stories to tell, and he played a few games of wizard chess with Al to pass the time, so he didn't feel bored along the way.The train arrived. When Harry and the students entered the auditorium together, he heard many students pointing at him. The Slytherin students even looked at him and whispered. It seemed that he was not in Defense Against the Dark Arts class. The news of the teacher has long been known to the students.

"Here you are, Harry." Headmaster Dippet shook Harry's hand in welcome, and Harry nodded to the other teachers and took the empty seat next to Flitwick.Harry had already met all the teachers at the staff meeting, including the vampire Humberur who never showed up in the auditorium.

The sorting ceremony was over, and Principal Dippet introduced the new Defense Against the Dark Arts teacher to the students. The students below looked at each other and applauded to express their congratulations.Harry noticed that the table with the most enthusiastic applause was actually the Slytherin table. On the contrary, the applause from Gryffindor was sparse, and few people gave face.

Harry's eyes fell on Tom, who sat perfectly upright.It's clear that Tom, sitting next to the first-years, is the central figure in Slytherin.Tom is a natural leader, Harry didn't notice this before, but now sitting in a group of peers, Tom's leadership qualities are very obvious.Alphard noticed Harry's gaze, and quietly poked Tom beside him, signaling with his eyes.Tom had obviously noticed it earlier, and calmly shifted his gaze to Harry's face, sending him a perfect smile.

Harry felt a little uncomfortable, the smile on Tom's face was clearly a mask, he was just putting on a show in front of everyone.Harry returned Tom a masked grin, turning his attention to the joke Dumbledore had just finished telling.

"Tom, there's Defense Against the Dark Arts class this afternoon." Alfred handed the schedule to Tom. "It's Ravenclaw in the seventh grade in the morning. They say Harry's class is very practical."

"I know." Tom glanced at the schedule and continued to eat his lunch.

"Tom."

"What's wrong?" Tom turned his head and met Alphard's puzzled eyes.

"You don't seem to be looking forward to this class." Alfred frowned, "It's Harry's class."

"You should call him Professor Potter." Tom corrected, "So what if it's Professor Potter's class?"

"Aren't you looking forward to it?" Arafat asked.

"Fourth graders should start learning spells," Tom replied casually, "but we already know those spells, don't we?"

"It's just some theory." Alfat looked around and lowered his voice, "Aren't you still angry with him?"

"Have I?" Tom asked indifferently. "I just want to know what Professor Potter will teach us in the first class. I hope that those defensive spells don't need us to learn by ourselves like before."

"Are you so unconfident in Professor Porter?" Alfart began to cut his lamb chops, "You also know his experiences, he is capable."

Tom snorted without answering.Of course he knew Harry was a capable wizard, but Tom didn't quite want to admit that he was actually curious about what Harry's first class was going to be like.

The classroom of Defense Against the Dark Arts class has not changed from before.Harry was not inside, and Harry came in from the outside when everyone was here.

"Good afternoon." Harry greeted everyone gently, and opened the roll call, "Let's do the roll call first."

After the last student finished answering, Harry put the roster aside: "I learned about your progress from Professor Mellors. Hogwarts Defense Against the Dark Arts has always been more theoretical, and I think it is only in the This course can only be mastered in practice.”

Harry looked at the little snakes below and exchanged surprised glances, and smiled slightly: "But this does not mean that we don't need to learn some basic theories. There are different forms of spells, and I just want to teach you how to break them," said Harry. All the little snakes except Tom looked disappointed, "In case you have the ability to defend yourself in the face of danger. Is there any problem, Mr. Riddle?"

"If we don't know the spells that can hurt us," Tom asked in a questioning, drawn tone, "how can we tell which spells we can't use?"

Everyone looked at Tom.Tom didn't seem to see those gazes, and his face was full of impeccable expectations.

"A very practical question, Tom." Harry curled his lips, "I'll tell you which spells you can't use, but that's not what we're going to learn in this class. What we're going to talk about in this class is the Iron Armor Charm .When you are attacked, this spell can form an armor-like protective layer around the caster to prevent injury. This spell can resist the attacks of most spells..."

This is indeed a successful Defense Against the Dark Arts class.Harry's explanations are easy to understand, and he focuses on practical training as much as he introduces himself.After Harry finished explaining the theory of the Iron Armor Curse, he divided the students into groups and instructed each student how to use the spell.In fact, for the Slytherins, the Iron Armor Curse is not very difficult. Many people will use this spell, and there are not many places that need Harry's guidance.But even little snakes know how to do it, and are more than happy to practice with their wands, rather than lying on the table and listening to dry theories.

"Great lesson, isn't it?" Alfart said to Tom after class, and Tom nodded irrefutably: "He should teach some more practical spells."

"You can give him some advice," Arffate said. "Professor Porter will be happy to hear your opinion."

"He's so well prepared himself that I don't need my advice," replied Tom casually.

"You can question Professor Porter from the very beginning." Arfart said sharply, "You are still angry with him."

"This is between me and Harry, Al." Tom looked at Alfred coldly.

"You'll always make up with him," Arafat said with certainty.Tom snorted and strode away.
