HP has a villain system but has become a popular character

There is actually a big bug in Hogwarts' dormitory rules.

Dormitory rules: Boys cannot enter the girls' dormitory, and they cannot even enter the passage leading to the girls' dormitory.

If the occupants are of the same gender, they will not be able to enter the dormitory unless the name of the occupant is on the doorplate.

This is where the problem lies. The names are hung outside the door. As long as someone hangs the doorplate with his or her name on the door of the dormitory he or she wants to enter, he or she can enter unimpeded.

This is how Wenxiu Lord and Severus got Lucius's spare clothes and toiletries these days.

The book page that Regulus had been stroking repeatedly in his hand was replaced by a metal nameplate. The smooth metal surface was engraved with frosted cursive letters, which flashed under the light, revealing Regulus Arcturus Black.

The young man stood up. There were evidences on the sofa that he had stayed there for a long time. The black tea on the coffee table beside him had already gone cold, much colder than the room temperature. He drank the tea in one gulp and opened the door of the ownerless single dormitory.

The corridors were cold and damp, a place where the professors' magic had no place to go.

Regulus slowly walked to the door of the dormitory where the two names were hung, and his eyes stopped at the first name tag. After a moment, he raised his hand and removed the name tag under Wenxiu Lord.

The owners of this dormitory are no longer Severus Snape and Vince Lord, but Regulus Arcturus Black and Vince Lord.

In Regulus's opinion, the two names placed neatly side by side were so pleasing to the eye that he stood there admiring them for a long time, his body almost frozen, before he reluctantly walked towards the common room.

Sirius and Remus stood at the door of the cellar. Without the password, they could not enter, and the small snake on the door handle would leave two bloody holes on their hands.

The two were wearing hospital gowns that were not warm enough. If Sirius hadn't cast a warming spell on them, not only would Remus have had a relapse of high fever, but his good brother Sirius would not have been loyal enough to accompany him.

Peeves followed behind the two of them, acting exaggeratedly and sneakily as if they were performing an exaggerated and funny silent movie.

Count Nicholas patted Peeves' shoulder expressionlessly, and the ghost who enjoyed playing pranks on people experienced the feeling of being scared.

"Nicholas, this is probably your most successful prank this year."

Count Nicholas shrugged noncommittally, "What have they been doing for so long? Are they planning to become ghosts to keep us company?"

The two of them spoke in low voices, and Remus and Sirius did not hear their complaints. Sirius rubbed his arms and said, "If I had known it was so cold, I should have asked James to bring two thick clothes over."

As a werewolf, Remus' body temperature is naturally higher than that of ordinary wizards. Now there is a warming spell on his body, and he feels that he can hold on for a while. "These two days are the biggest cold wave in England. You just happened to avoid it."

The two little snakes, awakened by the conversation, couldn't find the source of the noise, and tapped the door handle with their tails in dissatisfaction.

There was a movement from the inside of the door. Someone was pushing it. The two little snakes reluctantly separated from their entangled state, with one of them entangled around the door handle.

Sirius and Remus noticed the condition of the little snake and looked up. The next second, the door of the cellar was pushed open from the inside.

The two people in loose and thin hospital gowns saw Regulus' figure in the door. The boy was wearing warm clothes, not home clothes, but a shirt and a knitted sweater vest, and a tie. The material of the tie seemed to be too soft and a little shapeless. If someone carefully distinguished it, they could see that it was a headband. He was still wearing a school robe.

A warm wave of heat came from the lounge. Sirius flashed in and Regulus was knocked aside. Although he couldn't see him, he knew it must be Sirius.

Remus took advantage of the gap to enter the lounge, thanking the boy as he passed by.

The door of the lounge was closed. Fortunately, the fireplace was burning all day long, and the little bit of cold air that came in was quickly warmed up.

The sofa by the fireplace was sunken, and someone was sitting there. Sirius had no mood to look at the decoration here when he broke into the Slytherin lounge last time. Of course, he was not in the mood to appreciate the luxurious decoration here now. He just wanted to warm up quickly and then go to see Wenxiu Lord.

Remus had the same idea, and was even more anxious than Sirius, not even thinking about warming himself by the fire.

"Sirius, let's go."

Regulus walked to the single chair next to the two of them and sat down. "Sirius, come out after you confirm Wenxiu Lord's physical condition. Don't stay too long. The effect of this potion only lasts for three hours."

The potion lasted for three hours, which sounded lenient, but both Remus and Regulus knew that Sirius would not leave easily after seeing Vincius Lord.

Sirius waved his hand impatiently, remembering that no one could see his current state, he put down his hand and added, "I know, I know. I will definitely come out before the potion wears off."

"You must be kidding. That's Wen Xiu's sleeping face. How could I tell after just one look?"

The tone was perfunctory, and Regulus could only pin his hopes on Remus, "Remus, please keep an eye on my brother. I can't go in with you."

"Don't worry, I'll keep an eye on him."

In fact, after a few dozen seconds, Remus was the one who was more out of control.

Sirius stood up and said, "Let's go." He said it briskly and impatiently.

Two heads popped out of the ceiling, and Peeves and Count Nicholas looked at the three people who walked into the dormitory corridor, exclaiming in surprise.

"Wow, Gryffindor and Slytherin are working together, and the target of the prank is Slytherin. This is really exciting!"

With such a tone of watching the fun, Count Nicholas only hoped that Peeves would not encounter the Bloody Baron.

The three of them went downstairs, the temperature was getting lower and lower. Sirius, who was going deep into the Slytherin dormitory for the first time, lowered his sharp eyebrows, "Wen Xiu has been living in such a gloomy and cold place? I remember that he is very afraid of the cold, it's really suffering. He really should have gone to Gryffindor, which may be the warmest of the four dormitories."

Remus didn't agree with Sirius speaking ill of Slytherin in front of Slytherin students, but he agreed with the meaning of his words and added in his mind, 'If he is really sorted into Gryffindor, maybe he will be assigned to the same dormitory with us.'

I never thought about how likely it would be that Vinciu Lord would go to Hufflepuff if he didn't choose Slytherin.

Wenxiu Lord was very afraid of the cold. Regulus took note of this and did not refute Sirius' words. After all, Wenxiu Lord chose Slytherin and had the silver glow unique to Slytherin.

At the end of the spiral staircase was a pitch-black corridor. Regulus didn't even need to use the fluorescent flash. The location of the silver-haired boy's dormitory had been engraved in his mind thousands of times.

The two followed Regulus and saw him arrive at the door of Wenxiu Lord's dormitory with ease.

Looking at the names lined up neatly on the door, Remus said nothing. His eyes fell on Regulus's face, which showed no signs of abnormality, and he frowned in deep thought.

Sirius reached out and touched the metal nameplate belonging to Vinceau Lord. Regulus saw the position of the nameplate move slightly, and Severus's metal nameplate was tightly grasped in the palm of his hand, leaving two marks.

"Brother, what's wrong?"

Sirius, who was invisible, smiled meaningfully, "Nothing, open the door."
