Professor McGonagall, Hagrid was disappointed for Harry to become a Slytherin. For Professor Flitwick, he was disappointed with the brilliant student Lily Potter's son not being assigned to Ravenclaw which is only related to his eagerness towards academically excellent students.
Severus Snape on the other hand become more interested in Anthony Dumbledore as well as Harry Potter.
It seems that Anthony Dumbledore, who he hated him for being Albus Dumbledore's grandnephew is actually Harry Potter's friend. He is expecting to not spoil Harry Potter and Anthony Dumbledore to become like their relatives.
When Harry Potter was looking around the professors, he had eye contact with Professor Severus Snape. Suddenly, Harry's scar got hurt and he rubbed his forehead and asked Anthony,
"Anthony, who is the professor next to Professor Quirrel?" asked Harry with a curious tone.
Anthony who was seeing the entire situation understood that Voldemort who is on the back of Quirrel's head has his face directed towards Harry at this moment. It is the reason why Harry misunderstood that Professor Snape is perhaps a loyal follower of Voldemort.
"He is head of our house, Professor Severus Snape. He also teaches potions in Hogwarts. Harry, I strongly advise you to prepare for his classes." Anthony advised Harry. Due to Harry's miserable childhood, Anthony always thought that Harry at least deserved a happy Hogwarts experience.
Draco Malfoy who is opposite to Anthony suddenly opened his mouth and asked Anthony, "Anthony, I heard that your last name is Dumbledore, perhaps are you related to headmaster Albus Dumbledore?"
Anthony who repeated the same introduction many times said casually. "He is my granduncle, and my full name is not Anthony Dumbledore, but Anthony Lefrancois Dumbledore. My parents are both pureblood."
Draco becomes surprised that the deceasing Dumbledore family has a young heir with the same age as him. He looked at Harry Potter and said with a gentle tone "Harry Potter, it was wise for you to accept Lefrancois Dumbledore's advice. You never know when you crossroads with someone again. They are Grabbe and Coyle. My father's friends' children."
Albus Dumbledore stood up from his chair and the whole Great Hall become quiet. Dumbledore opened the Banquet with a simple yet profound speech "Welcome to a new year at Hogwarts! Before we begin our banquet, I would like to say a few words. And here they are Nitwit! Blubber! Oddment! Tweak!"
Soon the banquet started and glorious food magically appeared on the table. Anthony, who is bored with Leaky Cauldron's dishes, started to eat beef steak with fork and knives.
Harry who saw the table manner of Anthony and the rest of the Slytherin adjusted himself on the chair and started to eat the Hogwarts food slowly, even though it is his first time eating this elegant food, he understood that the food would not be gone soon, and therefore in Slytherin, you need to behave well.
Anthony who just thought that there was Orange juice filled his cup and drank a mouthful of juice, suddenly opened his as if he has drunk poison.
"Pumpkin juice, seriously! Pumpkin soup is acceptable, but pumpkin soup?!" Anthony becomes disgusted.
'Whoever thought that Pumpkin juice is delicious should be hanged! The Wizarding world needs some innovation on their beverage industry!' though Anthony.
"What happened Anthony? Are you alright?" asked Harry.
"Oh, Harry! Do you believe that it is Pumpkin juice instead of Orange? Can you believe it?" said Anthony with a high tone.
"Pumpkin juice? Does it taste well?" said Harry.
"Try it!" said Anthony with a smile on his face.
When Harry took a sip of the Pumpkin juice, his face immediately changed and become expressed his facial expression that he has just drunk the most disgusting juice ever.
'Seriously, the wizarding world needs more delicious juices, perhaps Orange juice, or Grenade juice. Even Seabuckthorn juice is not gross as Pumpkin juice! I bet Harry has the money to purchase some Seabuckthorn from Mongolia.'
When Anthony thought about Harry's glittering galleons in Gringotts, he just realized that even though he almost spent all of his funds on investment to Firebolt Company, there is still a millionaire next to him.
About an hour later, after getting acquainted with Slytherin students, Anthony, Harry, and the rest of Slytherin's first years followed the Slytherin Prefects towards the dungeon.
They arrived in front of the Slytherin common room portrait of Perseus Parkinson, the former Minister of Magic in the 1700s. The Slytherin prefect said "First years, don't forget the password. The password would change every month. So the new password would be posted on the board in the common room." He looked towards the portrait and said "Serpent!"
The portrait opened the frame and there was a greenish decorated common room of Slytherin.
When Anthony got inside, he found a room that his name was written on. It was a single dormitory room with a bed in it and a desk that he could do his homework. There was a magically enchanted glass window on the opposite side of the door.
Through the glass window, you could see the entire black sea as if it is daylight and the various sea creatures that are floating in the water. Anthony's belongings were already placed on his bed
Anthony invited Harry into his room and chatted about their experience in Hogwarts. After having a good conversation, Anthony was hesitant to whether ask about investment from Harry. But he become determined that the business he set up could be successful. Therefore instead of asking for investment, he decided to start a business with Harry Potter.
"Harry, I have a business idea. And would you like to be interested in becoming business partners and found a company" said Anthony with a confident voice.
For Harry, who he never owned any company before asked the general situation about establishing a company in magical britain.
Anthony explained the process how he found a company with Randolph Sputmore and the terms.
Harry becomes puzzled and asked Anthony "But even though if we open a business, what product would we make, and who will run the company?" asked.
Anthony contemplated for a moment and replied. "Harry, do you remember the disgusting pumpkin juice that we have drunk during the banquet?"
Harry thought about the disgusting pumpkin juice's after taste "Of course, it was the grossest... Wait do you mean you want to make a better juice?" said Harry.
"Exactly! It is not just about improving pumpkin juice but to produce a totally different beverage! Harry, do you remember the muggle canned sodas?" said Anthony.
Harry's eyes sparkled. In his mind, he though that If he can become independent in the Wizarding world, perhaps he wouldn't have to go to the Dursleys,
After a while, Anthony asked Harry to study various herbs and potions as well as regarding Intellectual property sections in the textbook of History of Magic class.
Soon enough, Harry Potter fueled by his dreams started to read the Potions and History of Magic textbook and started his academic journey.
On the other hand, Anthony, who didn't train on Wandless magic started to re-start his magical training.

Early in the morning, after breakfast, near the Dungeons in a room filled with cauldrons, rows of students sat behind the student desks chatting with each other.
"Anthony, I couldn't believe that there are over a thousand magical herbs that can be found in the Wizarding World. And most of them are actually just typical Muggle herbs with different names!" said Harry Potter enthusiastically.
Soon enough, Professor Snape rushed in the class and stood in front of the students.
"There will be no foolish wand-waving or silly incantations in this class. As such, I don't expect many of you to appreciate the subtle science and exact art that is potion-making. However, for those select few..." said Snape with his monotonous tone.
"Who possess, the predisposition... I can teach you how to bewitch the mind and ensnare the senses. I can tell you how to bottle fame, brew glory, and even put a stopper in death." he raises his tone.
When Professor Snape saw Harry Potter and his resemblance to James Potter, he decided to ask a question. "Mister Potter. Our new celebrity.Tell me, what would I get if I added powdered root of asphodel to an infusion of wormwood?
Harry who read regarding the herbs last night happened to know the answer and replied "you'd brew a sleeping potion 'so powerful it is known as the Draught of Living Death" looking at Professor Snape.
Professor Snape, who is looking at Harry Potter, who has prepared for potions, had a deja vu like feeling.
'The son got his mother's eyes and as well as her talent for potions.' Muttered Snape inwardly and
"Well why aren't ou all writing this down?" said Snape, regaining his composture and continued his potions class.
Harry Potter looked at Anthony, and whispered: "Thank you!"
