When Lawrence finished his prefect's routine and returned to the small carriage occupied by the twins, he frowned and watched the bursts of black mist coming out of the cauldron of the two, and the twins had no intention of stopping, they kept pouring some suspicious materials into the cauldron,

"This thing isn't going to explode, is it?" Lawrence pushed open the window and used magic to clear the black smoke, and the rain mixed with the cold wind made the air in the box refreshed.

"Maybe." Fred jokingly said that he extinguished the flame conjured by the magic, and kept stirring the liquid in the cauldron while the cooled liquid slowly solidified.

"We discovered by accident in one of our experiments," George explains, "that this thing has a particularly strong adhesion to our skin."

"It takes seven days for this thing to get rid of when it is applied to the skin." Fred said with great interest,

"So who are you going to turn into black?" Lawrence raised an eyebrow,

"We're thinking of new product content," Fred explains, "about a series of epistolary hoax products, newspapers, letters, textbooks, when the user opens our product, they hit the victim's face and print the words on people's faces......

"We'll send one to Percy when we've done it," said George maliciously, "and as soon as I open the envelope, he'll be a face full of all kinds of laws."

"I suppose that way Mr. Crouch will remember his name more easily." Fred said, looking worried about the sake of others,

"The most in-depth we've looked at now are letters, and there are all sorts of different envelopes, and there's that lovely pattern," George said in an innocent tone, pulling out a pink envelope with a heart on it, "Look at our prototype, this love letter version of what I think will be the best-selling, prank letter—"

"When you open it with joy, you will be greeted by a week-long declaration of singleness that will be on your face." Fred said briskly,

"The greater the expectation, the greater the disappointment, right?" George blinked,

"You two will be burned at the stake in ancient times." Lawrence exclaimed,

"It's okay, I guess we're supposed to be wizards, right?" George said that he put on his gloves, took out a small knife, cut a little of the solidified black hard piece in the cauldron, sharpened one end, and began to write on parchment,

"It's kind of like a Muggle pencil." Lawrence said,

"It's a little inconvenient," Fred nodded, "and we'll find a way to store it like ink, so that it can be used in more different ways."

"But it's not the same as a Muggle pencil." George grabbed Fred's hand and put the parchment over Fred's arm,

"Ahh

"Don't forget the last time it was your turn, you made me have dark circles under my eyes all week." George said,

"Oh, it was a little accident," Fred laughed, and he removed the parchment, and Lawrence leaned over to see what George had written.

"'Angelina is getting fat again—'?" Lawrence laughed and thought,

"Ahhhh Fred Crazy,

"I can't see it when I change into a long-sleeved uniform—huh?" George comforted him, but he suddenly showed a look of surprise, "Are you—"

"At that stage?" Lawrence raised an eyebrow,

"Hey, don't think I don't understand what you're saying." Fred said depressedly, Lawrence and George quickly glanced at each other, apparently they were a little uneasy?

"Oh, it doesn't matter," George said lightly, "Didn't Mom say there was a prom this year?" I think you should invite her."

"Speaking of prom, I'm glad I bought my own dress with George." Fred said, "Look at Ron—"

"Mom doesn't tell us when the prom is." George complained, "They're all mysterious."

"Traditionally, the ball is held at Christmas." Lawrence replied,

"Why do you know?" The twins asked in unison,

"Sirius gave me a hint, and I guessed what Hogwarts was going on." Lawrence shrugged,

"So what's going to be going on this year?" Fred asked hurriedly,

"Triwizard Tournament." Lawrence said solemnly,

"Are you kidding?" George struggled to find out from Lawrence's expression the bad smile he was used to when he joked,

"Sirius suggests that if it goes well, it will continue in five years," Lawrence explained, "Percy also said that it was hosted by their Department of International Magical Cooperation, didn't it?"

"Why didn't you say it before?" Fred complained,

"Because no one asks me." Lawrence grinned toothily, and the twins rolled their eyes together,

"Aha—so your ** will come to Luo too?" George said in a tone that looked like Percy had caught their pigtails,

"I don't know, we didn't mention it," Lawrence frowned, "and then, we're just pen pals, thank you."

"Don't do that, George," Fred blinked, "Lawrence is afraid we're going to receive our new product—"

"Waterproof kraft paper bags, huh?" George pondered,

"That's because it's raining all the time in England," Lawrence said, "and on a sunny day, it's just a normal envelope."

"So you're still communicating?" Fred raised an eyebrow,

"Just asking questions." Lawrence said, thinking for a moment and adding, "And practice English."

"How can there be so many questions?" George shrewdly asked, "And she wrote in her first letter that she would ask her father how to write in English, right?"

"You said," Fred asked curiously, "that she's really pretty, so she's really pretty?"

"Who do you say is beautiful, Fred?" Angelina pushed open the door of the box and asked, and Arya, another Gryffindor chaser, snickered from the side,

"Ah, listen to me, Angelina—" Fred jumped up from his seat,

"I didn't know I was so fat that I needed you to write it down on your arm?" Angelina raised her eyebrows, then turned away expressionlessly, and Arya hurriedly followed,

"Wait—listen to me—" Fred immediately chased after him,

"He doesn't know where he's going," George began to pack up his lab equipment, completely unaware of the culprit, "and he could call himself George."

"Love makes people dizzy—" Lawrence guessed,

"So who do you prefer?" George was curious,

"What do you mean?" Lawrence was puzzled,

"Hermione, Luna, or the Miss Delacour we never met?" George asked, and Fred returned to the box,

"It's alright, it's alright—" Fred looked relieved, and he asked, "What are you talking about?"

"I'm learning about Lawrence's emotional world." George laughed,

"Hermione, Luna, and Miss Delacul?" Fred's eyes lit up, it was clear that they were both interested in it, and they were on the same page,

"Why do you all think it's the three of them?" Lawrence was curious,

"I'll talk about Hermione first," Fred said excitedly, "You're all Muggle born, aren't you?" And when you were in fourth grade, you singled out seven Slytherins for her."

"That's because Malfoy said that word." Lawrence explains,

"But there's no denying that you admired her from the beginning," Fred said, "and it's rare to meet a Gryffindor who has also read Hogwarts, a piece of history." That's what you said, right?"

"Let's talk about Luna again," George cleared his throat, "You've fought against 'that man's' diary and the basilisk together, haven't you?" And then on the train last year, you helped her—"

"That's because of the Dementors." Lawrence explains,

"But admittedly, you've never done anything like this, have you?" George said, "You usually keep a little distance from girls."

"And Miss Delacour," said Fred, after a pause, "well, you've been 'pen pals' for a whole year, and you usually don't have that patience with strangers, remember what it was like for us first year to play pranks on the train?"

"I know, it's because she asked you questions, right?" Seeing Lawrence open his mouth and about to explain, George said this, Lawrence could only swallow back the words that came to his mouth,

"So who do you prefer?" Fred asked,

"I don't know, I think they're just friends—" Lawrence said, "and—put away the parchment and quill, George."

"Bah-" George felt a pity, Lawrence's gossip was very popular at Hogwarts,

"Truth?" Fred expressed skepticism,

"I think so?" Lawrence was not sure, he waved his wand, and the rag on the side began to clean Fred and George's cauldron, and water came out of the tip of the wand.

"I think they all have a certain affection for you." Fred shook his head and said, "If you like one of them too, you might as well go for it."

"How do you know?" Lawrence regretted it before he asked, because he saw the corners of Fred's mouth slightly raised, obviously waiting for him to ask this,

"Take the time turner, Hermione borrowed us for your sake," Fred said, "or we'll just go and see Professor Lupin off."

"Luna agrees with me and George, but she didn't cast a curse on you, did she?" Fred added, "You'd love to give us a curse on us who taught her a bunch of nonsense."

"As for Miss Delacour—I'm sure you wouldn't want to keep up with a little bastard like Malfoy for a year." Finally, Fred gives an unassailable example,

"......" Lawrence was speechless, and George couldn't help laughing,

"He's very good at this kind of thing, so we're all single," George said, patting Lawrence on the shoulder, "In terms of magic, you can beat twenty Fred with one, but with this kind of thing, Fred can beat twenty you, but you know, with a girlfriend, he sometimes forgets his brother."

"I'm jealous of you—and that youth flies, and sometimes love comes very suddenly—" Fred looked like a passer-by, and he was immediately surrounded by two bachelors in the carriage, the train slowed down, and the Hogwarts Express arrived at the terminal, and despite the heavy rain outside, the students couldn't wait to squeeze off the express train, and the new semester was about to start again.

Author's Note: Ah, good afternoon.

There is a basis for the fact that Fred opened the story, such as in episode 7, at Bill's wedding, Fred and George both saw a pair of beautiful twin sisters, and when George was still wondering whether to strike up a lawsuit, Fred went straight to action.
