Diary?

Dumbledore glanced at Muya. Clearly, he knew where she had been. "Investigate further. As long as no guilt has been proven, they are innocent, Severus," he said firmly.

"But what about my cat?" Filch shrieked.

Dumbledore said patiently, "We will cure her. Professor Sprout recently acquired some Mandrakes. Once they have grown and matured, we can brew a potion to bring Mrs. Norris back to life."

Lockhart, standing in front of Muya, cut in, "Leave it to me. I've brewed it a hundred times."

Muya gave a silent, derisive laugh, then retaliated by giving Snape's robes a hard tug.

Snape lowered his head to look at her and understood what Muya's eyes were saying: That guy is stealing your job.

"I believe I am the school's Potions class teacher."

The room fell silent at once. Muya could feel Lockhart's embarrassment. She had no idea who had given him the courage to show off in front of the youngest Potions prodigy.

"Ahem. You may all return now," Dumbledore said, looking at Harry and the other two, and...

The three exchanged glances, nodded to Muya, and left.

Filch picked up Mrs. Norris and left as well.

Seeing this, Dumbledore laughed. "Ha ha, this is youth."

"I confess." Muya raised her right hand.

"Hm. It seems our Miss Muya is quite self-aware." Snape reclaimed his robes.

Professor Sprout patted Muya's head. "Child, we are not putting a criminal on trial."

Muya nodded. "I went to the Room of Requirement."

That sentence seemed to startle every professor. Muya noticed that everyone's gaze had fallen on her.

"So it really is in the Room of Requirement," Lockhart muttered softly.

In the corner stood a female professor Muya had never seen before. She wore glasses, had messy hair, and a turban wrapped around her head.

Her lips kept moving, but Muya could not understand what she was saying.

"Why did you go there?" Snape was still the one speaking this time.

Muya took out the bottle again and handed it to Snape. "This contains a half-finished potion I made in the Room of Requirement."

Snape examined it, then returned the bottle to Muya.

McGonagall spoke up. "It is already very late. She should return to sleep."

Muya gave McGonagall a grateful look.

"Go back, child."

"Good night, professors."

Muya had not forgotten that she had classes tomorrow. She did not want to be late and get punished.

In the History of Magic classroom, everything was as sleepy as ever. Muya was scribbling away, having recently decided to modify that mannequin.

She thought again of how Fred and George wanted to develop Shield Charm hats, Shield Charm cloaks, and Shield Charm gloves. Those required the Shield Charm, which she had not learned yet.

Class ended quickly, and Muya and Shalian patted the half-asleep Hannah and Susan.

In the corridors, many students were discussing Mrs. Norris being petrified.

As for the wall with the writing on it, Filch spent the entire day scrubbing it, but the words still glimmered on the wall.

That afternoon, Muya went to find Calori.

"Good afternoon, Calori." After greeting him, Muya conjured a chair and sat down.

Calori propped himself up with one hand on the grass by the Black Lake. "Good afternoon, Ya."

"You do not seem to be in a very good mood. Is it because of what happened last night?" Calori touched Muya's face, the smile he usually wore absent.

Muya froze slightly. "You know about it?"

"Of course." Calori fished a diary that looked like a book out of the lake. "The red-haired little wizard from last time threw this in."

"This morning."

Calori chatted with Muya about a few other things, but since today was not suitable for telling his story, he sent Muya back to dinner first.

Holding the diary, Muya realized it was the one Ginny often carried around. She had thought it was a book before.

Dinner that day included Muya's favorite sweet-and-sour spare ribs. She only hoped they would not have as much sugar as last time.

After dinner, Muya placed the diary on the table in the dormitory, then went to find Fred and George.

"Oh, poor Little Badger. I hope you were not frightened too badly last night." For some reason, Fred and George had not been among the large crowd of students the previous night.

Muya had even silently complained about this unlucky Halloween. Last year, a Troll had gotten in. This year, Mrs. Norris had been petrified.

Seeing Muya looking listless, the two exchanged a glance. "Ya Ya, you look like a deflated balloon right now."

"Do you need your big brothers' warm hugs?" The two crouched down to meet her at eye level.

"I do." Muya hugged each of them, and at last, the corners of her mouth curled upward.

"Thank you, Mr. Twins."

In the corner, a golden head popped out.

Muya discussed the design sketches and product effects of the Shield Charm set with the two of them. It was only a hypothetical product for now, since Fred and George had only just begun learning the Shield Charm, while Muya had not started learning it yet.

It reminded Muya of the Apparition Snape had taught her. She could still only manage short distances.

Back in the dormitory, Muya sat at her desk, preparing to continue adding details to the mannequin. Suddenly, the diary she had brought back opened to its first page.

Strangely, what was written there was not Ginny's name, but an unfamiliar one: Tom Riddle.

Muya flipped to the middle, only to find it completely blank. She was puzzled. Why was this diary clearly not Ginny's, yet in Ginny's possession?

Was it a gift from someone else? A friend of hers? Or perhaps a pen pal?

Muya was still wondering about the diary's origins and did not notice words appearing on its pages.

"Hello."

"My name is Tom Riddle."

Snap. Muya shut the diary. Since it was an unfinished diary that nobody wanted, she decided not to think about it for now.

"Ya Ya, want to have a little midnight snack together?" Hannah had just returned from the kitchen. Shalian and Susan were still in the library.

Hearing Hannah's words, Muya immediately stood up. "Sure." Then she went with Hannah to eat the snacks she had brought back.

Diary: Hello? Can you see this? Don't tell me you're blind?

Because Muya had received too much candy last year, and Hermione had taught her about tooth extraction this year, she had not planned to ask for candy this year.

Muya once again arrived at her most hated class: Flying class.

Because she was afraid of heights, Muya could not fly too high. She liked flying low and slow, with the leisurely feel of retirement.

"Why are you flying so low and so slowly?" Draco suddenly dived down from above and came to Muya's side.

"Can't help it. I'm afraid of heights, young master."
