Tokyo: The Beginning of the Gauze Female Devil

"She's my Onii-chan's girlfriend!"

"Huh?!" Kawachi Ono widened his eyes and exclaimed in surprise.

"Is this the perfect rival that Ai-chan mentioned, who can handle everything from the living room to the kitchen, and can do anything?"

"It's really beautiful!"

Hearing about her is believing. Ogihara Saki does fit the image of a beautiful, gentle, and well-built girlfriend that Kawachi Ono had imagined, but the word "perfect" has not yet been fully reflected in her.

"Hello, sister-in-law!" she greeted warmly.

"Hello, Ono-chan..."

The word "sister-in-law" made Ogihara Saki smile sweetly, and her pretty face couldn't help but break into a beautiful and generous smile.

"My name is Ogihara Saki."

"Excuse me for visiting, please accept it." She said as she took out a box of dessert from her canvas bag and handed it over.

"Thank you sister-in-law!"

After taking the dessert box, Kawachi Ono's voice became a little more friendly.

"Come in quickly, no need to change into slippers..."

"Mom and Dad both went to work, and I'm the only one at home."

"This Ono-chan!"

Shimizu Ai gritted her teeth secretly.

"I haven't even called her 'sister-in-law' yet, but she did it first!"

After taking off her Mary Jane shoes and canvas shoes, two pairs of slender legs, one black and one white, wrapped in stockings, walked in on the floor.

……

At the kotatsu, Kawachi Ono poured them a cup of hot tea.

The three women sat on the floor and stretched their legs into the warm kotatsu.

"Shhh-"

Putting her schoolbag aside, Shimizu Ai took out her exercise book, took out a pen and paper and began to review today's homework.

With Ogiwara Saki around, she dared not be lazy, because although Saki-sister was not the type to tell tales, she could not resist her onii-chan's questioning.

Seeing that Shimizu Ai, an excellent student, was working so hard, Kawachi Ono, who had average grades, did not slack off either and picked up a pen to solve math problems.

Ogihara Saki, who was sitting next to the two of them, moved slowly, trying not to make any noise to disturb them, and picked up a review book and began to flip through it.

In fact, during the winter vacation, Ogihara Saki has been thinking about preparing for the teacher qualification examination.

The Japanese teacher qualification examination is held once a year, and the specific time is not fixed, roughly between July and December. In short, there is plenty of time.

However, Ogiwara Saki has not yet decided whether to become a teacher in the future, or what subject to teach, so she thought about asking Fujii Itsuki for advice in a few days.

"Aiyi-chan..."

The quiet atmosphere lasted for more than half an hour and was finally broken by the voice of the host, Kawachi Ono.

"How do you do this question?" she asked as she pushed the exercise book and draft paper towards Shimizu Ai who was standing across from the kotatsu.

"Let me take a look..." Putting down the unfinished English cloze test, Shimizu Ai took the exercise book, paper and pen, and began to look at them carefully.

"Shhh-"

1 minutes, 2 minutes, 5 minutes...

Time passed minute by minute, and three sheets of draft paper were used up. Shimizu Ai scratched her hair, still unable to figure out the answer. She was not even sure whether her solution was correct.

"Aiyi-chan, can you do it?" Ono-chan beside her questioned softly.

"Why are you in such a hurry?" Shimizu Ai pouted.

"……Let me do it."

Just when she was at a loss and scratching her head, a soft and calming voice came to her ears, soothing the irritability in her heart.

Before Shimizu Ai could react, the oil-based pen in her hand was taken away by the girl.

"Shhh-"

Holding a marker, Ogihara Saki briefly read the question and began to write and draw on the draft paper.

"Saki-nee-san..."

"Can you really solve it?"

Looking at her concentrated look, Shimizu Ai blinked her big eyes suspiciously.

I remember that Ogiwara Saki and Fujii Jise were attending the same ordinary university. The only advantage of this university was that it was close to home. It was not as good as the private higher education institution attended by her sister Shimizu Rin.

And the ability of modern college students to answer questions, those who know know...

Unexpectedly, the problem that took her ten minutes to figure out, Ogihara Saki solved it completely in just two minutes.

"So easy?"

“Is the answer wrong?”

A hint of surprise flashed across Shimizu Ai's eyes.

"Ai-chan, Ono-chan..."

Spreading the draft paper in front of the two people, Ogihara Saki explained to them patiently step by step in a gentle voice.

"First of all, this problem requires differential equations."

"..."

Ogihara Saki explained everything in great detail for several minutes, but Kawachi Ono shook his head in confusion and said truthfully: "I don't understand at all!"

Even Shimizu Ai, the top student sitting across from her, showed a confused look on her face.

"no……"

"Saki-nee is really good at solving this problem!!"

“And it sounds very profound.”

"It doesn't matter if you don't understand."

Ogihara Saki narrowed her eyes and said softly to the two of them, "This question is beyond the syllabus. You won't learn differential equations until college."

"Don't worry, these won't be tested in the unified exam."

"So this is college math!"

"Ai knew it!" Shimizu Ai's twin ponytails stood up again and she rolled her eyes at Kawachi Ono.

"I'm sorry, Ai-chan..."

"I shouldn't have questioned you just now." Kawachi Ono hugged Shimizu Ai's arm and said flatteringly.

but……

After this incident, both of them had more respect for Ogihara Saki.

Kawachi Ono even took out a notebook of difficult questions and peppered Ogihara Saki with questions one by one.

"really……"

"This onee-chan is just like what Ai-chan said, she's not just gentle and pretty!"

Even Shimizu Ai picked out a few difficult questions and brought them over.

"Saki-nee can do these extra questions, right?"

Ogihara Saki patiently answered their questions one by one.

……

Time is like running water, passing by in a flash in the busy life.

"Woo——"

"I'm so tired." Raising her slender arms and stretching her sore and soft waist, Shimizu Ai muttered to herself while stretching.

"Not only am I tired, but I'm also hungry." Kawachi Ono, who was sitting opposite her, lay down and rubbed his flat belly.

As for Ogihara Saki, who was standing beside the two of them, she picked up the mobile phone on the kotatsu and checked the time.

At 11:35 am, it's time to go for lunch.

"Snapped--"

She clapped her slender hands gently, attracting the attention of the two men.

"Does anyone want to eat grilled beef tongue?" Ogihara Saki smiled brightly on her delicate face.

"I know there's a really delicious grilled beef tongue restaurant over at Kashimada Shopping Street. I've been there a few times when I was dating Shu."

"Grilled beef tongue?"

Shimizu Ai and Kawachi Ono looked at each other in bewilderment.

"I'm fine with this. The weather is so cold, it's perfect for eating barbecue!" Shimizu Ai agreed in a sweet voice.

"Although I want to eat too, it's too cold outside and I don't want to go out for the time being..." Kawachi Ono lay down again, almost curled up in the kotatsu.

"Why don't we wait until it's warmer outside before going out?" she suggested in a low voice.

"How can there be people who are afraid of the cold but not hunger?" Shimizu Ai glanced at Kawachi Ono unhappily.

Kawachi Ono, her deskmate and good friend, was not ashamed but proud of it. She turned over and rolled towards Shimizu Ai.

"Aiyi-chan, don't you know how to cook?"

"There are ready-made ingredients in the refrigerator. How about Ai Yi-chan cook a feast herself?"

"I'm too hungry. I don't want to do it..." Shimizu Ai's face fell and she lay down.

"Let me do it." Familiar words came out of Ogihara Saki's mouth, and she slowly stood up from the kotatsu.

"Ono-chan, where is the kitchen?"

"Over there..." Kawachi Ono subconsciously stretched out his little hand and pointed in a direction.

After she saw her back walk into the kitchen, she hesitantly asked Shimizu Ai, "Ai-chan, can she cook?"

"Boom."

At home, she is often hit on the forehead by her onii-chan and onee-chan, but in front of her good friend Kawachi Ono, Shimizu Ai can finally hold herself together for once.

Retracting her hand, she asked meaningfully, "Do you know what it means to be a woman among women, a female among females, the strongest and most perfect 'rival in love' in history?"

"I don't know..." Kawachi Ono covered his forehead and blinked confusedly.

……

……

The dining table was filled with the aroma of food.

"delicious!"

Kawachi Ono's cheeks were bulging with delicious food. While chewing, he did not forget to put some food into the bowl.

Although Ogihara Saki only made a simple dish of chicken thighs stewed with potatoes and braised eggplant, Kawachi Ono kept shoveling food into his mouth like a beggar who had been fleeing for a long time.

"Woooooooo..."

"That's too much, Ono-chan." Shimizu Ai said with a look of disdain, and also took a bite of eggplant rice. She completely forgot that her eating habits were not much different from Kawachi Ono's.

"strangeness……"

It was a very homely meal, and the method was simple, but Shimizu Ai always felt that she was just a little bit short of Ogiwara Saki's skill.

“I’m so full…”

The meal took less than half an hour. After eating and drinking, Kawachi Ono rubbed his round belly, with a grain of rice still left at the corner of his mouth.

Shimizu Ai crossed her slender legs wrapped in white stockings, and also fell into a tired atmosphere of not knowing what to do after eating.

"Aiyi-chan, are we still reviewing in the afternoon?"

"I don't know..." After hearing Kawachi Ono's question, Shimizu Ai turned her gaze to Ogihara Saki next to her.
