Today the weather was very good, the sun was very bright, Fujiwara Touko got up early and moved the quilts to the yard to dry in the sun, breakfast was already prepared on the table. Just as she was struggling to move the last quilt, the doorbell suddenly rang. Fujiwara Touko took a breath, put down the quilt that was shaking with effort, walked to the door and opened it a little, "Excuse me...what can I do for you?"

Fujiwara Touko looked at the strange man outside and asked puzzledly.

"Hello," the man smiled, "Excuse me, is this Takashi Natsume's house?"

"Yes, who are you?" Fujiwara Toko replied.

The man looked relieved. "I'm Natsume's teacher. I came to visit you today. I was in a hurry and forgot to call you in advance. I'm very sorry to bother you."

Fujiwara Toko raised her right hand and covered her lips with it: "Takashi-kun's teacher? Hello, hello, please come in. I'm sorry, Takashi-kun is still sleeping. I'll go wake him up now."

The man walked in and said, "Excuse me."

They walked and talked as they entered the first floor. At the entrance of the stairs, they met Natsume Takashi who was just coming downstairs and the cat teacher at his feet. Fujiwara Toko said, "Takashi-kun, come down quickly, the teacher is visiting!"

Natsume Takashi met the man's gaze with a confused look on his face. "Home visit?"

Fujiwara Toko smiled and said, "Yes, teacher, would you like to have breakfast with us?"

Before the man could say anything, Natsume Takashi said, "No need, Aunt Tachi! I remembered that the teacher said that he would check the homework as soon as he arrived. I'll take him back to his room first!"

As soon as he finished speaking, Natsume Takashi pulled the man upstairs, not giving Fujiwara Touko any time to react, leaving Fujiwara Touko standing at the stairs with a helpless smile and said, "Oh, Takashi-kun, are you afraid that the teacher will complain?" She raised her head and put her hand on her chin to think about it, then clapped her hands, "Since the teacher is here, breakfast may not be enough, so let's make more delicious food to treat the teacher well!"

The kitchen downstairs was bustling with activity, but in Natsume Takashi's room upstairs, it was not like what Natsume Takashi said, where he was checking homework for the visiting teacher. Instead, it was cold.

Natsume Takashi stood there with a vigilant look on his face. The cat teacher said beside his feet: "Be careful, Natsume. I don't smell any evil spirit on him. This could be a big monster!"

The man who was guarded by Takashi Natsume and Teacher Cat curled his lips, raised his hand and wiped his face, revealing his true face hidden under the mask. He looked to be about 25 or 26 years old, wearing a white shirt and black pants, and looked exactly like Takashi Natsume. It was not an exaggeration to say that he was an enlarged version of Takashi Natsume.

"How could this happen?!"

"What do you want to do by turning into Natsume?!"

The voices of Takashi Natsume and Teacher Cat rang out at the same time. It seemed that Takashi Natsume had fully prepared his "face-breaking punch" and was just waiting for the opportunity to deliver a punch.

"Hello, I'm the 26-year-old Natsume Takashi, from the future," the man who called himself the future Natsume Takashi thought for a moment and added, "It could also be a parallel world."

Natsume Takashi: ???

Natsume Takashi: !!!

Teacher Cat jumped up and looked at him on the table. "We won't believe you so easily just because of one sentence. What evidence do you have to prove it?"

The older Natsume said, "Then I'll start from my childhood. Even if it's a monster in disguise, it's impossible for it to remember its childhood so clearly, right?"

After that, the man who claimed to be the future Natsume Takashi spoke about the past as if he was reciting a book. Natsume Takashi's alert expression gradually relaxed as the man spoke. After the man finished speaking, Natsume Takashi and the cat teacher looked at each other, nodded and said, "He is not wrong."

Natsume Takashi asked, "Then how did you get here? What is your purpose?"

The older Natsume looked at the cat teacher on the table, "This is an accident. Mr. Deba once told me that I would have a wonderful journey in the future, but it would be short, and gave me a mask that could cover my original appearance, which is the one you just saw. So as soon as I came here and figured out the situation, I put on the mask and came to find my younger self." He moved his eyes to Natsume Takashi, "By the way, I'm a teacher now."

Natsume Takashi nodded blankly, "Didn't the cat teacher come with you?"

The older Natsume suddenly fell silent, half-shaking his head, his smile tinged with bitterness, "I can no longer see Teacher Cat, and I don't know where Teacher Cat is, but from what you said, it seems that Teacher Cat didn't come with me."

Natsume Takashi opened his mouth and wanted to say something to comfort her, but the words that came to his mouth turned into a question, "Are you okay?"

As soon as he said this, Natsume Takashi suddenly felt a little annoyed. It would have been better if he could have answered it more nicely. Natsume Takashi thought so. He did not look well. Why did he ask such a question?

Natsume, who looked older and had become a teacher, smiled softly. He raised his hand and patted his younger self, "I'm fine, don't worry. Although I don't know when I will leave, because meeting and parting are fleeting, I want to cherish every moment."*

He lowered his eyebrows, leaned down and picked up the cat teacher who had walked to his side at some point, his eyes full of nostalgia and loneliness, "Even if we can only interact with each other briefly like this, it is an important encounter that can support our souls, that's what I think."

The older Natsume lowered his head and looked at the cat teacher in his arms, with the familiar smile of the cat teacher appearing on his face, "Also, long time no see, teacher."

It was the same smile that appeared on my face instinctively when I saw my trusted cat teacher when I was young.
