The Chinese girl from Hufflepuff is both timid and brave

"Can you tell me what happy thing happened to you? He keeps this weird smile all the time, and his deterrent power is no less than that of a Dementor." Fina was flipping through the ancient rune notes, and she felt a throbbing pain in her head. Occasionally, she looked up at the opposite side, but found that Sun Zhu was not reading at all.

Her face was so distorted that even if Madam Pomfrey came, she might not be able to help her recover. Diggory, on the other hand, looked helpless. If this wasn't a library, she would have wanted to yell and throw both of them out.

Fina rubbed her temple and nudged Karina, who was almost asleep on the table, with her elbow.

Karina sat up straight, looked around blankly, and found that she was not in the Potions class. She was about to lie down again.

"If you keep going like this, you won't even get an A in Arithmancy, Potions, and History of Magic." Since she was hurt by the two people opposite her, she chose to transfer the hurt to the innocent Carina. "Even if you don't need to get the OWLS certificates for these courses to be a professional Quidditch player, you can't join us when we have classes later."

Karina immediately made a bitter face and began to force herself to look through her notes again.

Hearing this, Sun Zhu briefly returned to normal: "It's okay if we can't take classes together, but we can't not even get an A. Come on, Karina. If you don't understand something, ask Sayid!"

Cedric lowered his head and placed his hand on his forehead, wondering what he was thinking.

"Student Digory, why don't you say anything? Are you unwilling to help us?" Sun Zhu leaned closer and said in a voice that was loud enough for all four of them to hear: "Could it be that you are the kind of person who appears warm on the outside but is actually cold on the inside, and you are not..."

Cedric suddenly reached out and fixed her head on his shoulder, and used his other hand to rub her face mercilessly again and again, trying to straighten her facial features that were distorted and twitching because of trying not to laugh.

"Hey...hey, you!" Sun Zhu tried to protest, but couldn't even utter a complete sentence.

And someone completely ignored Karina's surprised look, and even seemed to take off his disguise, whispering: "Yes, classmate Sun, I am indeed a very bad person. It's a pity that you find out now."

Karina half opened her mouth: "No? Did I miss anything while I was asleep?"

Fina covered her eyes and pretended that these three people did not exist.

When Sun Zhu tried to open his mouth to bite him, someone finally withdrew his evil hand. Unfortunately, before she could protest, she found Ms. Pings walking towards them.

Karina still had her mouth half open as she watched the two people opposite her quickly return to normal and seamlessly switch to serious study mode.

Karina cried silently: "Is there anyone here who cares whether I live or die?"

Could it be that they thought she was too stupid and finally decided to abandon her?

She reached out to shake Fina, but Fina spread her hands and said, "I can't explain it to you because I have no idea what's going on."

Sun Zhu also began to rub his face: "Sorry, I just remembered something funny. Well, I mean you should continue studying. If you don't understand something, you can ask us."

"Not including me." Someone said sullenly, "After all, I'm not the kind of person who is polite to everyone."

Fina's eyes were about to roll up to the ceiling: "For Karina's sake, why don't you stay somewhere else."

"If we leave, she will fall asleep again soon." Sun Zhu said confidently, pointing and saying, "Look, she is so energetic now, her eyes are full of desire for knowledge!"

Karina blinked her eyes: "What were you talking about just now? Why did Cedric say he was a 'very bad person'?"

Fina looked in her bag for a while, then took out a potion that Karina was very familiar with and ordered, "Drink it."

"The child is just a little curious. There's no need to be so ruthless as to feed him poison directly!" Although she recognized that it was a magic potion developed by Fina's family with stable effects and low side effects, equivalent to an enhanced version of "coffee cooling oil mixture", she still couldn't help but say something mean, "No, Karina——"

Karina drank it all in one gulp, and soon her forehead was covered with mist that floated from nowhere. Could it be the steam from the water in her brain? She glanced at the textbook again, and her eyes suddenly became cloudy but full of wisdom.

"Uh..." Sun Zhu scratched his head, "Wait, is the drug too strong? I think it's just an OWLS exam, but it's okay, there's no need to use such strong ingredients."

Although all Hogwarts potions are somewhat mysterious, the more abstract they are, the better the effect.

"Just for the exam? Isn't there a mysterious man who is about to come back?" Fina stood up expressionlessly, pulled Sun Zhu's sleeve and dragged her to the exit of the library, "I will watch Karina and let her learn something useful, not just for the exam. Don't worry, it won't be excessive. But when we return to the dormitory tonight, I need you to explain your abnormal behavior today. Now, please do as you please."

Fina pulled her past several tables, and the students who were reading almost ignored the noise they made - those who would come to the library at this time were either fifth or seventh graders, and more than half of them were Ravenclaws.

Seeing this, Cedric consciously put all the books and stationery that Sun Zhu had left on the table into his book bag. Before leaving, he looked at Karina, who was flipping through the book with shining eyes, and felt a little sympathetic.

After thinking for a moment, he placed the notes on Arithmancy and Defense Against the Dark Arts next to Karina.

When he came to Sun Zhu with his schoolbag, Fina pointed at them and said, "I believe you two must be busy with something. Go quickly, the library will only limit your pace. Whether you want to do something earth-shattering or something shameful... Anyway, I wish you good luck."

After being kicked out of the library by her roommate, Sun Zhu looked at someone who had been following her silently: "What's with that expression on your face? Did the Dementors do anything to you?"

"I have encountered something more terrible than the Dementors." He hung his head. "If I can't solve it, there may be no happiness in the future."

Sun Zhu looked serious and asked like a serious person: "Mr. Diggory, do you mean that even though you didn't encounter the Dementors, you will lose your future happiness? It's hard to imagine that such a thing would happen in Hogwarts. What are you going to do?"

Cedric's voice froze for a moment, then he quickly said calmly, "I don't know what I can do. But I can be sure of one thing..."

"What is it?"

"My happiness, both now and in the future, is in your hands."
