Being at Hogwarts, something's not right with this system.

Ever since Lin Yu kissed Hermione in front of everyone in the restaurant's grand hall that morning, news that the two had become a couple spread quickly.

There's really no way around it, since life at Hogwarts is quite dull and boring.

So the young wizards love to talk about gossip.

Moreover, this matter reached Professor McGonagall's ears, and she was also present that morning.

So, during the first Transfiguration class of the week, Professor McGonagall had to warn Lin Yu and Hermione: "While I won't interfere with whether you're in a relationship or not, you must promise that it won't affect your studies."

In Professor McGonagall's eyes, Hermione and Lin Yu were practically her precious darlings.

A smart and ambitious female student, and a Seeker who was specially recruited into the Quidditch team by her.

She didn't want them to become worse off just because they were in a relationship.

"Of course," Lin Yu replied, "we will only get better, Professor McGonagall."

Hermione lowered her head, too embarrassed to respond in public.

Professor McGonagall looked serious, but she was actually suppressing a smile, and couldn't help but think to herself, "Young people are so lucky; they can still feel the bittersweetness of love."

When Professor McGonagall thought of herself again, she felt a wave of sadness wash over her.

Because she had a failed marriage, or rather, she was widowed.

Professor McGonagall sighed softly, forced a smile, and began the lesson.

After the class ended, Lin Yu caught up with Professor McGonagall: "Professor McGonagall, please wait a moment."

Professor McGonagall stopped in the corridor, looking at him with a puzzled expression.

Lin Yu approached Professor McGonagall alone and said, "Actually, I wanted to ask you something. If I want someone to buy something for me from Diagon Alley, how do I get it brought to me? Hermione's birthday is coming up, and I'm planning to get her a birthday present. And then there's Christmas. But I'm more curious, why do we wizards celebrate Christmas?"

Professor McGonagall rolled her eyes at Lin Yu: "After all, there are still many children from wizarding families or who are of mixed race. I'm mixed race myself, and my father is a priest. Why would you think we don't celebrate Christmas?"

Lin Yu's lips twitched, wondering if it would be impolite to say that the burning of witches in the Middle Ages was orchestrated by the church.

However, in general, while hunting activities may have religious significance, they are not entirely purely religious acts.

In short, Lin Yu wasn't quite sure either; he was just making a comment.

"If you want to buy something from Diagon Alley, you'll either have to send a message to someone you know, or you'll have to ask me or another professor," Professor McGonagall said.

Without thinking, Lin Yu put his hands together in a pleading gesture and said, "Then I can only ask you for help, my old dean."

Professor McGonagall rolled her eyes again. Was she that old?

"What do you want to buy as a gift?" Professor McGonagall didn't rush to agree, but instead asked Lin Yu what he wanted to buy first, and warned him, "Let me make it clear beforehand, your broom was approved by Dumbledore, so you can't buy it for anyone else."

"Of course," Lin Yu agreed. "Actually, I wanted to ask you to buy a cat from a pet store as a gift for Hermione. After all, my pet is a cat. And Hermione really likes our cat, Huru."

Lin Yu wondered if it was just his imagination, but he seemed to see a hint of relief on Professor McGonagall's face.

Lin Yu suddenly remembered, right, Professor McGonagall is actually a registered Animagus, a wizard who can freely transform himself into an animal.

Moreover, this transformation is completely flawless, a genuine transformation into an animal, so convincing that even magic would have difficulty detecting it.

Wasn't that how Sirius Black escaped Azkaban, turning into a dog?

Professor McGonagall's animal form happens to be a cat.

So, Professor McGonagall was relieved when Lin Yu said that he and Hermione both loved cats?

After all, Animagus are like having a dual identity; their animal identity is also a part of them, making them two sides of the same coin.

"Okay, I understand," Professor McGonagall nodded and said, "I'll talk to you about the price after your gift arrives."

With that, Professor McGonagall prepared to leave.

Lin Yu added, "By the way, Professor, if I remember correctly, I once encountered a cat named Crookshanks. Although it wasn't particularly beautiful, the shop assistant said it had raccoon ancestry. You could try buying it. Perhaps you could mention it briefly in the letter, saying that Harry Potter's friend wants to buy the cat."

Professor McGonagall gave Lin Yu a strange look, wondering why he had brought it up on purpose, but she still nodded in agreement.

Actually, it was Lin Yu who remembered that Crook Mountain had cat-raccoon blood, so it was very intelligent and could distinguish between good and evil.

Therefore, Crookshan is not a place that everyone is close to.

Moreover, Lin Yu vaguely remembered seeing some interesting speculations in his previous life: Harry's parents had once owned a cat, but it disappeared later.

Crookshank was boarded at a pet store for a long time without anyone buying it. Maybe it has some connection with Harry's family?

After all, Crookshank and Sirius seemed to know each other well and trust each other a lot.

What Lin Yu didn't know was that in the novel, Crookshank even knew how to stop the Whomping Willow from moving; it actually knew the location of the Whomping Willow's mechanism.

In short, Lin Yu still really wanted to buy Hermione the Crookshanks from the movie as a birthday present.

"What did you say to Professor McGonagall?" Hermione asked as she stepped out from behind.

Lin Yu ran too fast, and she didn't have time to catch up.

Lin Yu looked at Hermione and, without hiding anything, said directly, "I remember your birthday is coming up soon, so I asked Professor McGonagall to buy you a birthday present. But I won't tell you what it is."

Hermione remembered that Lin Yu had indeed asked her what her birthday was before, apparently to prepare for her birthday.

Hermione immediately flashed a sweet smile; she was ready to welcome the surprise her boyfriend had in store for her.

"What are you talking about?"

Ron and Harry also came out and saw the two of them standing in the corridor, smiling at each other, but they didn't have the sense to go up and disturb them.

Harry followed behind Ron, and even shrugged at Lin Yu, as if to say it was none of his business.

Lin Yu wanted to tease Ron, so he said, "I originally wanted to prepare a broom for you as a Christmas present, but Professor McGonagall said that first-year students are not allowed to play with brooms except for me, so I'm sorry, Ron."

Ron indeed looked disappointed.

Hermione shook her head, exposing Lin Yu's lie: "Don't listen to him, Ron, he's buying me a birthday present."

Ron blinked, then instinctively asked, "Is it your birthday? Should we give you a birthday present too?"

Hermione immediately became unhappy and snorted, "Give it or don't, it's up to you."

She turned and left.

Lin Yu gave Ron a meaningful look, then chased after his girlfriend and left.

Harry sighed and said, "Ron, you still don't consider Hermione a friend? But at least Lin Yu is our friend. We should at least get Hermione a birthday present."

Hermione was unhappy because ever since Ron publicly told her that she was unlikable, they still didn't treat her as a friend.

As expected, only Lin Yu likes her, so she'll only like Lin Yu too.
