Felix politely said goodbye and left.

In the afternoon class, he was rarely distracted.

"Please turn the book to page 147. Let's take a look at how ancient wizards viewed the concept of 'existence'."

"Professor? This part we were talking about in the last class..." a little wizard raised his hand and said.

Felix showed a surprised expression. He looked at the textbook and said, "It's indeed my problem. I must apologize to you. This also shows a problem. The professor is also a human being, and there must be times when he makes mistakes..."

"Okay, let's turn to page 152. Today we are going to talk about ancient magical texts related to 'hope'."

The Weasley twins in the audience looked at each other, and Fred squeezed his eyes: 'It's rare that Professor Hayp made a mistake in class.'

George lipped: ‘We witnessed history.’

Fred pinched George's thigh and stopped himself from making a sound.

After class, the twins surrounded Felix.

After answering several questions, Fred asked curiously: "Professor, is there anything we can help?"

"What?"

"Oh, professor," George said with a chuckle, "we think you may have a little trouble, and although it will certainly be solved, maybe we can do something."

Felix smiled, "Gentlemen Weasleys, I have nothing...well," he looked at the two of them and asked thoughtfully, "Can you get a magic camera?"

He knew that the little wizards had a small circle in private similar to a flea market, with all kinds of novel and interesting gadgets.

"Professor, can Muggle cameras and development potions be OK? The effect is the same," Fred said.

"Yes," George explained: "Creeve, a first-year-old, bought the developing potion we bought, but he brought the camera."

Felix thought for a while and said, "Yes."

Within two days, he received the camera, film and development potion.

He paid the final payment readily.

During the following week, Felix and Helena chatted, they deliberately ignored the conflict that night.

Felix introduced interesting things outside, even the secrets of the year he traveled.

"You're really caught by Aurors in the American magic black market?" she asked in surprise.

"I can't say that, it's just a coincidence that they're going to catch up with their actions. I originally wanted to slip away with the crowd - anyway, everyone is covered with their faces, and the phantom will move after they go out."

"What?" she asked with interest.

"Seven Aurors recognized me and stared at me and chased me..." Felix said with regret, "I had to knock them down."

That was his first actual combat with the instant killing tactic, but in order to increase the speed of his thinking, he took a bottle of magic potion and had a headache for a week.

"pity……"

"What a pity?" Felix asked.

"It's a pity that I can't use magic, and I even lost most of the memories related to the casting of magic." She said regretfully: "The ghost is not complete, I only have a particularly deep memory of my death..."

"What about other memories?"

"Either blurry or no resonance, it's like watching a stranger's experience..." she said.

And at this moment, he finally made up his mind.

Felix said: "Helena, there's something I need to tell you."

"What's up?"

Felix hesitated for a moment, and he took out the camera, "Can I take a picture of you?"

Helena looked at him in surprise, she hesitated for a moment in reserve and agreed happily.

Felix took a few solo photos of Helena, and finally took another photo of the two.

"It may take a day or two to get the developer to work," he said.

He looked at the smile on Helena's face and felt a surge in his heart. Helena saw the expression on his face and slowly calmed down, "Isn't you talking about this? Is this a difficult thing for you, Felix?"

"Do you know that you have any requests?

"Uh, oh..." She stroked her hair in panic, "I know, it was a laboratory built by my mother. I often went there when I was a child, but my mother didn't want to be disturbed, but I always went against her."

"Have you been there again? I mean..." He paused, "After becoming a ghost."

"No, no." She said dryly.

Felix knew in his heart that she deliberately avoided this place out of guilt or self-punishment.

He whispered: "I found something left by Ms. Ravenclaw in it, probably about you."

"Why—what did you say!" She flew over quickly, staring at him tightly, as if to tell if it was a bad joke.

Felix looked into her eyes calmly, without any intention of joking.

Helena believed it.

She asked anxiously, "What? What did she leave?" Her translucent pearly white body floated in the air, her hands trying to grab Felix's shoulder, but she passed through it.

A coldness that broke through the bone marrow made Felix shudder.

"It's a memory," he whispered.

...

For the next few days, Helena kept hiding from him.

Felix understood her very well. This feeling of worrying about gains and losses was not good. Who can guarantee that Ms. Ravenclaw's memory must be left to Helena?

Can memory be awakened by ghosts?

After awakening, do you remain rational?

Be rational, can you get the desired result?

Although the answers to these questions are likely to be "yes", no one can be sure except the moment the truth is revealed.

During this period, Felix harvested seven photos. With the effect of the developer and the adjustment of his magic, Helena was like a real person, beautiful, tall, and a smile on her lips.

Finally, on a weekend morning, she found Felix.

"Take me there," she said calmly.

"You decided?"

She nodded solemnly, and no matter what the result was, she would accept it.

In front of the eighth floor's Responsive House, Felix and Helena stood quietly.

A blue door slowly appeared, Helena looked at him, and Felix grabbed the handle and pushed open the door.

Felix stepped into the room again, with a Helena next to him - or rather, he was the guest.

As Helena stepped into the house of Responsibility, the whole room became active.

A small voice came from all directions of them. Even without changing their perspective, Felix could feel a huge magic power awakening.

The furnishings in the house continue to disappear, and the space continues to expand until it becomes a white world with no edges.

The sky and the earth seem to have lost their boundaries, leaving only Felix and Helena.

Not far away in front of Helena, magic gathered surgingly, outlining the figure of a lady.

From illusion to reality, she came from nothingness.
