Hogwarts , my sister is Hermione

"Harry, hello, this is Professor McGonagall." Hagrid said to Harry behind him.

Harry then walked out and greeted Professor McGonagall:

"Hello, Professor McGonagall."

"Hello, Mr. Potter." Professor McGonagall nodded, and then introduced Louis and Hermione: "This is Hagrid, the gamekeeper of Hogwarts, and this is Harry Potter."

,Mr. Potter will be your classmate in the future."

"Hello, Hagrid." Louis greeted the big Hagrid, then looked at Harry and asked tentatively:

"Hello, Harry, can I call you that?"

"Of course, but what should I call you?" Harry responded.

"Oh! My name is Louis Granger, you can just call me Louis."

"Well, although it may be a little offensive, I'm still curious." At this time, Hermione spoke up, looking at Hagrid, who was nearly 4 meters tall, with a little curiosity and asked: "Excuse me, why are you so tall?

"

"Hagrid has giant blood, he told me this." Harry thought of what Hagrid had said before and said smoothly instead of Hagrid. Hagrid did not refute, but just blinked.

"Giant blood!" Hermione said in surprise: "There are actually giants in this world!"

"Hermione!" Louis stopped Hermione's loud voice and whispered in her ear: "It is very impolite to talk about other people's origins!"

When her brother said this, Hermione also reacted and quickly apologized: "Sorry, I didn't mean to do it, I was just a little surprised."

"Oh, it's okay, I'm used to it." Hagrid obviously didn't care about this, and then said to Professor McGonagall: "Professor McGonagall, I'm leaving it to you. I'm a little uncomfortable with Gringotts' car. I plan to

Let’s go get a refreshing drink.”

"Of course, no problem, go ahead." Professor McGonagall agreed.

And just when Hagrid asked Professor McGonagall, Louis, Hermione, and Harry were already chatting happily.

Seeing that the three of them had been chatting for a while and had become familiar with each other, and seemed to have made friends, Professor McGonagall interrupted them, pointed to Madam Malkin's robe shop and said:

"Mr. Granger, Miss Granger, and Mr. Potter, I don't think I meant to interrupt your conversation, but I think you need to go in and buy some suitable clothes now?"

Hearing Professor McGonagall's words, the three little ones blushed visibly.

Finally, under the leadership of Professor McGonagall, the three of them entered the store.

Just when the three of them entered the store, Louis happened to see a young man with silver hair, pale face, and thin body walking out.

After entering the store, Louis looked back the moment the door was about to close, and saw the young man walking towards a middle-aged man with silver hair.

At this moment, Louis thought of the time they were delayed in front of the store just now.

Has the world line changed?

No, the world line started to change as early as the moment he came to this world, but it wasn't until this moment.

The experience of Harry, who was originally destined to be the son of destiny and the savior of this world, was also changed by him.

Missed my first meeting with Draco Malfoy.

And Louis didn't think about communicating with the Malfoy family. After all, there was Lucius in their family who did not hesitate to surrender to Voldemort when he returned.

So Louis' own background alone is enough to disgust the Malfoy family.

But he swore that if the young man named Draco couldn't control his mouth later, he would definitely let the other person taste it. What would be the consequences of oral pleasure!

In Madam Malkin's robe shop, the three little ones quickly measured themselves. After agreeing that the clothes would be mailed to them by owl, Louis readily paid the Galleons. Harry's share was

He paid for it himself. After all, they had just met. Excessive enthusiasm would make others doubt and alienate him.

Then several people were led by Professor McGonagall, planning to buy wands.

"Hey Louis, we're going to have our own wands soon!"

"What does the wand look like? Is it the same as the one in your novel?" Hermione thought in confusion.

"Novel, does Louis still write novels?" Harry asked unexpectedly.

At this point, Hermione looked a little proud: "Do you know "The Fellowship of the Ring"?"

"I heard that my aunt bought it for Dudley, and I secretly took a look at the world inside when they were not around..."

Halfway through the words, Harry suddenly reacted. He looked at Hermione and Louis in surprise, and had a bold idea in his mind:

"You mean?"

"Yes, that was written by my brother Louis!"

At this point, the proud look on Hermione's face was undoubtedly revealed. What belongs to her brother belongs to her sister, and what belongs to her sister belongs to her brother, so is there anything wrong with her being a little proud? Not at all.

Harry looked at Louis, and for a moment he didn't know how to face it.

"Okay, sister, there is no need to bring this matter up."

Louis saw the change in Harry's expression and was a little worried that Harry would be estranged because of this matter. He immediately interrupted Hermione and comforted Harry:

"Don't worry, you don't have to think of me as a star or some unreachable writer. I am also an ordinary person. Besides, we were already friends just now, right?"

"Okay!" Harry nodded heavily.

Louis' comfort immediately made Harry let go of the slight sense of distance that had been rising for a moment.

It also made him feel that it seemed good to have friends?

This also deepened the relationship between Harry and Louis.

I'm afraid the only one who had an objection was Hermione, who was interrupted by Louis. When she saw Louis interrupting her to comfort Harry, she didn't know why, but she felt a little uncomfortable.

Hermione, who was a little sensitive, also thought about Louis' current achievements, which can be said to be very dazzling.

But as a sister, Keji is still...

That's all, I still have to work harder, so that at least I won't be embarrassed in front of my brother~

Next, Hermione seemed to have started a conversation, constantly expressing her doubts and thoughts.

His eyes looked at Professor McGonagall from time to time, hoping to get answers from her.

Harry, on the other hand, occasionally chimed in.

"How is the wand used and what is its principle?"

"Speaking of which, it seems that the admission notice says that you can bring a pet. What do you think is good?

Owl? You can send things, but it’s a bit conspicuous, and you can’t take it with you.

Toad? Forget it, too ugly.

So what kind of pet should I keep?”

"I think the owl is better, more practical, and the most important thing is that it can send letters to friends, which is the best!" This is what Harry said.

"No, it's too conspicuous."

Professor McGonagall didn't care about the discussion of the three little ones behind, and kept walking in front.

It's just that I always feel like I've forgotten something, and something is missing.

Louis didn't want to argue. After all, it was always unwise to argue about an unnecessary issue.

The two people in front of me seemed to want to convince each other.

For him, as long as he likes pets, he would like to get a thunderbird, but it would be a bit of a punishment.
