Arriving at Morimi Bookstore, Kazuyo is organizing the bookshelves.
"Are you here?"
After saying hello to her parents, she picked up her schoolbag and followed Naruse and the others to the Maki Hotel diagonally opposite.
"Would you like to have a study meeting together? It would be great."
Maki Seiichiro was a little happy, and Haixing quickly came down from upstairs.
"Be careful on the road."
"Okay." Naruse stayed behind, "We will send Haixing back."
"I feel relieved when Harumi is here." Seiichiro said.
Naruse said nothing and nodded.
Following the companion in front, Haixing glanced at him one more time and then looked ahead.
Walking in the snow, one step at a time, Mori saw that his home was not close, but in this case it seemed further away.
"Walking this way every day will take a lot of time." Naruse stepped on the white snow and looked back at Morimi, "Why don't you live over there at the bookstore."
"I'm happy."
"..."
Seeing him roll his eyes, Morimi smiled briefly.
"There's nothing wrong with taking a few more steps. Such a long walk is just the right time to sort out your mood."
"That's right..."
Takigawa Hikaru nodded in understanding, "If I have to walk such a long way before going out, I might become numb to school."
"You are not talking about the same thing at all, don't be numb."
After walking forward for a while, Naruse narrowed his eyes.
"Almost there."
Shangzi took his arm and raised his gaze, seeing that Mori's house was right in front.
Starfish exhaled a puff of cold air and shrank his neck again, "It's finally here..."
"There is no air conditioning in my house." Morimi said from the side.
"Hey, isn't it cold?"
"Resist with your will, and you won't feel cold anymore."
"Eh..."
She smiled.
When they arrived at Morimi's house, Haixing realized that she was joking - her old house did not have air conditioning, but it did have a kotatsu and an electric heater.
"Can five people sit down?" When Naruse was at home, he turned on the air conditioner in the room and the floor heating in the living room. He had never used a kotatsu.
"You can still sit down if you squeeze in." Morimi put down his schoolbag, "You guys sit down first, I'll make tea."
Shangzi followed, "I'm here to help."
"No need...what is this?" Morimi suddenly noticed what she brought over.
"Rice balls." Shangzi smiled slightly, "When you are hungry, let's eat together."
Morimi looked at her twice more and couldn't help but shake her head: "When I'm with Naoko, I always feel like I'm not a girl."
Shangzi smiled, "How could that be?"
When the two returned to the living room, Naruse, Hikaru Takigawa and Haixing had already gotten into the kotatsu, and the former was looking down at it.
"There should be a switch or something... There seems to be an electric heater under the table."
"The switch is over here." Morimi put down the cup, lifted the quilt, and skillfully turned on the electric heater.
"Ah, it's getting hot." Hikaru Takigawa quickly gave feedback.
Morimi smiled and pointed to another electric heater placed outside, "Does this need to be turned on?"
"No, a kotatsu is enough."
The three of them sat on each side of the kotatsu on the four sides. Naoko naturally sat next to Naruse, squeezed in with him, and gave up the empty seat to Morimi.
Next to him is Starfish, and Hikari Takigawa sits opposite.
When Morimi also sat on the kotatsu, his ten legs were intertwined under the quilt, so intimate that it couldn't be more intimate.
"Don't press me...Whose leg is this?"
"Wait a minute, Chunhai, please don't move."
"I haven't moved..."
It took a while to adjust before everyone was satisfied.
"Let's get started."
According to the pattern in the library in the afternoon, several people continued to hold a study meeting.
Haixing, Naoko and Hikaru Takigawa found their own problems by doing exercises. Naruse and Morimi were responsible for answering questions for the three of them, checking and filling in the gaps and looking for their own loopholes. Kanshu La Kanshu Di
"Yiye, what does this sentence mean?"
"Let's see... do you recognize this word?"
"I don't know."
"This is a new word I learned this semester. Didn't I take the test before?"
Morimi was flipping through the vocabulary book and explaining to Takigawa Hikari. At a certain moment, he suddenly raised his head and looked at the starfish opposite: "Is there any question?"
She hesitated to speak and looked at her for a long time.
Haixing picked up the exercise book and said, "This question..."
Morimi glanced at it and said, "Naruse."
"Let me take a look." Naruse took the exercise book and put it between them, "Which question?"
Haixing looked at him and stretched out a finger, "This."
It was a very simple question, and it was also a common type. Naruse looked at it twice and almost calculated the answer in his mind.
It’s just that he has to let Haixing understand his thoughts.
"The problem is to ask for the minimum value of this quadratic function in this interval. Why can't you understand it?"
"No...I understand, but the number in the answer is different from the normal answer."
"Well, it's different..."
Isn’t that what you did wrong?
"Let me see your process."
Haixing handed over the draft, and Naruse glanced at it and discovered the problem.
"Before finding the extreme value, have you confirmed the position of the vertex?"
Haixing looked at him and shook his head.
"Then please reconfirm and try again."
Haixing took back his draft book and exercise book, and just as he was about to start working, he heard him add:
"No matter whether you are sure or not, drawing a sketch when solving quadratic function problems can help you avoid many mistakes."
"Oh..."
After a while, Naruse heard her suddenly take a breath and understood where she had made her mistake.
After a while, she lowered her head and said, "It's done."
"Yeah."
Naruse responded without saying anything more.
"Chunhai..."
When his attention returned to his side, Shangzi was struggling with a topic that he had to think about for a while.
“I can’t see the solution to the problem at a glance.”
"It's okay. This question is very difficult. Even Mori Mian can't figure it out at a glance."
"..."
Morimi, who was teaching grammar to Takigawa Hikaru, glanced sideways at him.
Shangzi smiled.
"This question is a bit complicated and not easy to explain... I'll do it first and then explain it to Shangzi."
"Yeah, okay."
It's freezing outside and the wind and snow are howling.
In the warm kotatsu room, two people tutored three people. They were busy but not nervous, and everyone enjoyed themselves.
Time flowed silently, and at a certain moment, Takigawa Hikari's cell phone vibrated.
"Whose news... Wow, is it already this time? Mom asked me when I would go back."
Naruse also looked at the time and realized that it was almost eleven o'clock in the evening.
The five of them actually sat motionless in the kotatsu for three or four hours.
"Um - are you going back?" Morimi stretched himself restrainedly.
"It's getting late..."
Takigawa Hikaru pulled out her legs with some difficulty, climbed out of the kotatsu, and immediately got in again.
"Wow, it's so cold!... Let's stay a little longer."
"The longer you stay in the kotatsu, the less you want to leave."
"Well..."
She lay down and said, "Just for a while."
After coming back to his senses, Haixing couldn't sit still and reluctantly climbed out of the kotatsu.
"Starfish?"
"I'll go...over there."
She pointed in the direction of the toilet.
The kotatsu was a little empty, so Naruse could move his legs and stretch his upper body.
After he settled down, Shangzi leaned over again and asked, "Are you hungry?"
"A little bit."
"Want to eat rice balls?"
"Eat."
Naoko climbed out of the kotatsu, and Morimi also came out, "It's been so long, the rice balls have become cold, right? There is a microwave in the kitchen."
"Great, let's heat it up."
The two left the living room, leaving only Naruse and Takigawa Hikari in the kotatsu.
She drilled down again, only her head was exposed.
"It's so comfortable..."
"Don't fall asleep."
"I don't want to go home. Chunhai, let's sleep here at night."
"..."
Naruse looked at the lattice door. The wind and snow were howling outside. He really didn't want to leave this warm place.
But I can only think about it.
"Don't fall asleep."
"I got it."
After a while, Haixing returned to the living room, his footsteps suddenly stopped.
"...Where are they?"
"Go to the kitchen to heat up the rice balls," Naruse said.
"Oh..."
She walked slowly and took her time, taking a long time to come here.
Not alone...
While Naruse was thinking, Haixing, who returned to the kotatsu, suddenly let out a low cry.
"Yeah——"
"Hahaha..."
There was a burst of laughter from the kotatsu.
Boom!
The table suddenly pushed up, and the laughter stopped abruptly.
"——What's wrong?"
Hearing the noise here, Morimi hurried back to the living room, only to see Hikaru Takigawa covering his head and moaning, while Haixing stood aside, a little at a loss.
