Tokyo: Starting with a fake boyfriend

I didn't sleep well last night.

Shiratori Osamu, who was opening his schoolbag to get his textbooks, nodded without denying it.

He slept very poorly last night. Although he could fall asleep as soon as his head hit the pillow after turning off dual mode, he had many nightmares.

Whenever he closed his eyes, the tearful face of Yamabuki Minami and the pitiful figure of Hojo Yuki would always appear before him.

He didn't know how many times he was startled awake throughout the entire night; he only felt that he had slept in a daze.

"Didn't you sleep well? Why don't you take a nap first?"

Upon learning of this situation, Shinonome Mizuki couldn't help but feel a little sorry for her.

Could it be that Shiratori-kun has been studying so hard lately, neglecting sleep and meals, that he's exhausted because he wants to do well on next Wednesday's final math exam?

"No need, let's begin."

Shiratori Osamu shook his head, placed "Mathematics B" on the table, opened it, and immediately entered a state of desperate counterattack and complete concentration.

With only four and a half days left until the final exams, after finishing this "Mathematics B" book, he still has to tackle the most difficult "Mathematics III" and "Mathematics C" books. He has no time to sleep anymore.

Go all out—this time, the timeline option was truly accurate.

"Math B? Why is he looking at Math B?"

At the same time, Shinonome Mizuki, sitting opposite him, noticed the textbook in his hand and suddenly became puzzled.

The next moment, a terrible thought surfaced in her mind:

"Wait a minute, is he planning to start from Math I and work his way up to Math C before the final exams?"

Although she hoped that Shiratori-kun would perform well in the final math exam, so that the other teachers could appreciate the potential of a science genius and her discerning eye.

However, her expectations were actually very low; she only hoped that Shiratori-kun's math score would rise significantly, for example, from single digits to the 60-70 range.

If Shiratori-kun, a science genius, could finish learning the core courses of "Mathematics I", "Mathematics II" and "Mathematics III" before the final exam, he might be able to raise his score to 80-100 points.

As a liberal arts student with a rich imagination, this was already the highest expectation Shinonome Mizuki had.

However, to her complete surprise, Shiratori-kun was still studying the three vertical thematic courses: "Mathematics A", "Mathematics B", and "Mathematics C".

"When Shiratori-kun said he was 90% confident, what score did he actually aim for?"

Upon realizing his study plan, Shinonome Mizuki's heart suddenly raced.

What terrified her even more was that Shiratori-kun seemed to be planning to learn the entire three-year math curriculum for science students in just half a month.

If Shiratori-kun could really do this, she couldn't even estimate how many points he would get.

If she scores 50-69 points, all the teachers and students in the school will feel Shiratori Osamu's learning attitude and potential, and will know that her choice was right.

If she scores 70-100, all the teachers and students in the school will realize that Shiratori Osamu is a promising talent, and everyone will look at her with new respect.

If she scores 110 or above, the entire school will be shocked and will call her a science genius. Everyone will think she is a talent scout.

Even with her rich imagination, Shinonome Mizuki couldn't fathom what the outcome would be if it were over 120 points, because it was simply too fantastical.

After a moment of euphoric excitement, Shinonome Mizuki, having caught up in her imagination, looked at Shiratori Osamu, who was now completely absorbed in his work, and frowned with worry.

"Shiratori-kun's study schedule is too demanding, and he looks very tired today. We need to find a way to help him relax."

Studying diligently is a good thing, but everything should be done in moderation. If you ruin your health for the sake of studying, then it will be a loss.

Moreover, final exams don't really have any real significance; they're just a way to assess students' progress throughout the semester. The key is still the university entrance exam.

"Someone is watching me..."

At the same time, Shiratori Osamu, who was focused on his studies, suddenly felt a furtive gaze on him, and his heart tightened.

When people realize they are being watched, they usually become suspicious... He was in that situation. Considering Hojo Ryoma's observation, he was constantly on edge on his way home last night, and only felt at ease after arriving home.

Is he one of Hojo Ryoma's subordinates? Or a student from Takeno High School?

After a week of speculation, the rumor that Mr. Shinonome tutored him in the Aozora study room on the weekend was already common knowledge at Takeno High School.

It is foreseeable that if any students happen to be in Shibuya on the weekend, they might want to come and verify the truth of the rumors.

"Since there's an opportunity, we should seize it." Although he didn't know which side it was, Shiratori Xiu suddenly looked up after a brief moment of thought.

Looking up, he saw Professor Dongyun peeking out from behind the glass door connecting the reception area and the study room, secretly watching him.

"No way, how did he manage to spot me like that?"

Dongyun Qianxing, who was peeking through the door, was startled when her handsome brother-in-law, who had been looking down at his book a moment ago, suddenly looked up at her without warning. Her face paled.

"Teacher Shinonome—no, this Teacher Shinonome isn't wearing glasses, and his expressions are too varied."

Catching the person secretly observing him, Shiratori Osamu subconsciously looked across and saw Shinonome Mizuki, wearing frameless glasses and exuding a cool and intellectual aura, sitting opposite him.

Are Shinonome Mizuki and Shinonome Chisei twin sisters?

In a state of flow, Shiratori looked left and right and compared the situation, realizing the situation in less than a second.

"Qianxing? What's she doing here? Is she following me?"

At the same time, Shinonome Mizuki noticed the situation at the doorway because Shiratori Osamu suddenly looked up, and her face immediately darkened.

Chapter 108 My Brother-in-Law is So Good

When her stalking was exposed, Shinonome Chisei hesitated for less than five seconds before decisively leaving a thousand-yen bill at the front desk and walking into the study room.

"Brother-in-law, hello."

Upon arriving at her seat and sitting next to her sister, Shinonome Chisei, dressed in a black T-shirt, jeans, and white chunky sneakers, looking quite elegant, called out to Shiratori Osamu.

What are you yelling about?

Higashino Mizuki, who was still angry, was startled when she heard this address and quickly reached out to pinch her arm to stop her.

"Brother-in-law, my sister has gone mad, help... ugh ugh ugh."

After being pinched on the arm, Dongyun Qianxing immediately looked for help from the other side.

"Shut up!"

However, before she could finish speaking, Higashion Mizuki covered her mouth.

Although Dongyun Qianxing couldn't speak because her sister forcibly covered her mouth, she breathed a sigh of relief.

Seeing her sister's expression turn dark instantly, her first reaction was to run away.

But then she thought that even if she escaped home, it would be useless. Facing her sister alone at night would only make things worse.

Since that's the case, she might as well take the initiative and seek her brother-in-law's help; perhaps she can turn the situation around.

"..."

As they played around together, Shiratori Shu didn't say anything, but he figured out a lot of things.

Actually, his previous idea of ​​having two wives was just wishful thinking and empty talk. After all, he was already incredibly lucky to be with Shinonome Mizuki, who resembled General Raiden and had a cold exterior but a warm heart.

As for his sister-in-law, his attitude was that if he had her, he was lucky; if he lost her, it was fate, and there was no need to force it.

But after realizing that his sister-in-law, Shinonome Chisei, was a twin sister, his thoughts changed: "What nonsense about losing them is my fate! I must find a way to win them both over!"

His thinking might seem scummy and greedy, but regardless of what others think, he simply cannot tolerate Shinonome Chisei, who looks exactly like Shinonome Mizuki but has a different temperament and personality, being with other men.

Why did Shinonome Chisei call him brother-in-law right away? Did Shinonome Mizuki not even bother to act at home, just hanging his photos all over the walls of her room, making it obvious to anyone with eyes that she likes him?

"Don't shout nonsense, Shiratori-kun has a girlfriend!"

At the same time, Shinonome Mizuki pinned her younger sister to the sofa and whispered a warning in her ear.

"what?"

Upon hearing this, Shinonome Chisei was stunned.

Just now, my sister saw how seriously my brother-in-law was studying, his eyes were practically drooling with desire, and she thought the two of them were a couple.

Even if they're not lovers, they're at least in an ambiguous relationship that's more than friends but not quite lovers.

Now her sister is telling her that Shiratori-kun is someone else's boyfriend?

Although she understands the principles that "good men are all other people's boyfriends" and "I don't want a man that no one wants either"... when did my sister become so depraved?

"Shut up."

Noticing her strange and indescribable gaze, Higashion Mizuki glared at her with some embarrassment and annoyance, then released her after giving her another warning.

"This Shiratori-kun is too handsome, no wonder my sister fell into depravity." Sitting up again, Shinonome Chisei initially couldn't understand, but after looking at the boy opposite her, she immediately understood.

As a gargame expert, she is very clear about the principle that 'beauty is justice'.

In the game, whether it's a world-destroying demon king, a long-legged sadist, or even a little brat who likes to shout "minor fish, minor fish," as long as the character model looks good enough, none of these are problems.

Besides, having a girlfriend doesn't mean having a wife, so it's normal for the older sister to want to compete for it.

Never mind, never mind. I don't understand, but I respect her decision. I'll try to help my sister.

"I'm sorry, Shiratori-kun... My sister has a rather eccentric personality, and I don't understand why she calls you that. Please don't mind."

Having successfully silenced her younger sister, Shinonome Mizuki's face burned uncontrollably as she thought about what had just happened.

Although she had always known that her younger sister had a rather eccentric personality, almost like she was missing a screw, this time it was just too crazy.

"It's okay, I don't mind."

As for the issue of address, Shiratori Osamu naturally didn't mind and shook his head.

He reads him as "elder brother" but writes him as "brother-in-law." When he sees Shinonome Chisei calling him "Onii-san" with a face that looks exactly like Shinonome-sensei's, what does he have to mind?

"Let me introduce you. This is my younger sister, Shinonome Chisei."

Having resolved the awkward situation, Shinonome Mizuki, after some thought, decided to give a proper introduction.

"Just call me Qianxing. Please take good care of me, brother-in-law."

Unlike her older sister, who is serious and rigid, Shinonome Chisei is cheerful and free-spirited, and her whole demeanor is different.

"#"

Discovering that she was so overly familiar with everyone and immediately asked someone to call her "Chishin" so intimately, and even called her "brother-in-law," Higashion Mizuki didn't say anything, but her face was gloomy and the veins on her forehead were bulging, glaring at her with murderous eyes.

“My brother-in-law said he doesn’t mind…”

Dongyun Qianxing was already used to being glared at by her and wasn't afraid, but just muttered resentfully.

She's a galgame expert; she dares to say that when Shiratori-kun heard her call him "brother-in-law," although he didn't show any expression on his face, he was absolutely overjoyed inside.

"Let me introduce you. This is Shiratori Osamu. He is eighteen years old, a third-year high school student, and my student."

If it weren't for the study room and Shiratori-kun watching, Shinonome Mizuki would have wanted to strangle her, and she introduced the situation with a cold face.

"what?"

Upon learning Shiratori Osamu's age and identity, Shinonome Chisei was once again dumbfounded.

No, what is her older sister doing? Why does she have to go this far?

"You can call me whatever you want. Please take care of me, Dongyun-san."

At the same time, Shiratori Osamu seized the opportunity to speak at the right time.

The other person can be very casual, but he can't do this. Calling someone by their name right after meeting them is too intimate and might backfire.

"What if I call you a nobody?"

Seeing that he didn't mind being called brother-in-law, Dongyun Qianxing nodded and suddenly asked.

"?"

Even though Shiratori Osamu thinks very quickly, he still couldn't keep up with her unconventional thinking immediately.

No, her personality is way too quirky! What kind of style is this? A little devil?

"I was just kidding."

Seeing his serious and focused expression, clearly surprised by her, Dongyun Qianxing chuckled.

"Cough cough!"

Just then, a cough was heard from the surrounding area.

Hearing the noise, all three looked in the direction of the sound.

Having successfully captured their attention, the female clerk at the front desk pointed to the "No Noisy" sign on the wall.
