Tokyo Tutor: Starting with My Ex-Girlfriend's Sister

Himeno Saki's vision grew increasingly blurry. Her hand holding the pen trembled as she stared blankly at the question on the paper, completely at a loss for where to begin.

My head hurts so much, I can't understand a word Yamazaki-sensei said!

Large tears dripped onto the draft paper, and despair and regret filled Himeno Saki's heart.

After discovering that he had a talent for becoming a game streamer, he became increasingly uninterested in studying.

But she really didn't want to lose Mr. Yamazaki. It was not easy to find someone who could understand her, and Himeno Saki didn't want to be separated from him.

[Yamazaki-sensei has already done so well; I can't let him down.]

Himeno Saki slumped onto the table, too exhausted to continue.

The phone rang, and Himeno Saki picked it up, somewhat surprised to see that it was Yamazaki Kazufu calling.

"Saki-kun, are you still doing your homework?"

"How did you know, Mr. Yamazaki?"

"Stop working on it for now, get some rest. We can work on the problems you didn't understand tomorrow."

"But at this rate, we're running out of time. If we keep going on for days like this with each question, we won't even be able to pass this week's test."

"Don't worry, I have a solution. I can speed up your learning progress tomorrow."

"Huh, really?"

Himeno Saki was a little incredulous.

"Yes, don't worry. Go to sleep, you'll be energetic for class tomorrow."

"Yes."

Hearing Yamazaki Kazukaze's confidence, Himeno Saki Ryo put down her phone.

"Are you sure everything's okay?"

Himeno Saki was somewhat incredulous. Could Yamazaki Kazuka really have his pig brain blessed?

But Yamazaki Kazuka spoke with such confidence that I should trust him.

With hope in her heart, Himeno Saki closed her eyes, looking forward to how Yamazaki Kazukaze would help her out of her predicament tomorrow.

A ray of morning light shone through the curtains into Himeno Saki's room.

"ha."

Himeno Saki opened her eyes. She had a strange dream last night in which she got first place in her grade.

What a bizarre dream! I woke up laughing halfway through it.

Last night, Ms. Yamazaki assured herself that she would definitely find a way to change her situation today.

Although I don't know what he will do, I still choose to believe him.

Himeno Saki walked to the wardrobe and began to choose her clothes for the day.

My mom finally went on a business trip, so I can finally wear some clothes that suit my own style.

Saki Himeno likes to wear cool, sporty clothes to show off her good figure and athleticism.

That old fogey would never accept being dressed like that and sharing a room with a man.

A couple of days ago, I asked Uesugi Aoi to pick out clothes for me. The two of them have similar tastes, so I can nag less.

Today, I want to show Mr. Yamazaki the real me.

Having chosen her outerwear and shorts, Himeno Saki took off her nightgown.

Wearing only underwear, Himeno Saki walked to the mirror and stretched.

He casually placed his hand in front of his chest and gestured.

"I need to buy a larger bra."

Most of Himeno's clothes are custom-made by professional designers, which is sometimes more convenient than express delivery.

"Saki-kun... Wow!"

Uesugi Aoi, who was about to wake Himeno Saki, pushed open the door and was startled to see Himeno Saki gesturing in front of the mirror.

"Honestly, didn't you know to knock before coming in?"

Himeno Saki covered her chest.

"Yes, I'm sorry. I thought you were still sleeping."

"I'll choose and dress myself today, so you don't need to bother."

"Yes, yes."

"I almost forgot, I haven't chosen a bra yet."

The thought of almost going to see Mr. Yamazaki with her upper body exposed made Himeno Saki blush.

"Choosing black looks more mature; he seems to like mature styles."

Himeno Saki looked through the bras and finally chose a black rose bra to wear.

"Go for it, Himeno Saki, you can do it!"

Himeno Saki put her hands behind her back and tried to put on her bra.

Unexpectedly, being too well-developed was also a mistake. My waist was so slender, but my chest was too bulky.

To make it easier to exert force, Himeno Saki bent over and looked at her pert buttocks in the mirror, a shy blush immediately rising on her face.

"We have to hurry, otherwise it will be too embarrassing if Aunt Uesugi sees us."

After much effort, Himeno Saki finally got dressed and took out her phone to order several new bras online.

Then she put on a cropped top and tight shorts, and combed her hair in front of the mirror.

"Yes, this is more like me. This outfit will definitely catch Yamazaki-sensei's eye today."

After tying her hair into a single ponytail, Himeno Saki started putting on makeup.

Because she likes to wear light makeup, Himeno Saki quickly left her room and went to the kitchen today.

"Saki-san, you're awake."

Aunt Uesugi placed a glass of milk on the table.

"Yes. Hasn't Aoi come out yet?"

"She's still getting dressed."

"She just likes to put all that powder on her face; it looks disgusting."

When Uesugi Aoi stepped out of the room and saw Himeno Saki Ryo dressed like this, her eyes widened in surprise.

【No, Sakura-san, you're incredibly brave to dress like that.】

I was too conservative the other day. Doesn't Himeno Saki feel ashamed of what she's wearing?

Uesugi Aoi, dressed in a simple light gray dress, sat opposite Himeno Saki.

"Aoi, hurry up and eat, Mr. Yamazaki will be here soon."

"Yes, Grandma."

Uesugi Aoi didn't understand why Himeno Saki was so confident.

Ding-dong, the doorbell rang. Himeno Saki, having finished her meal, went to open the door.

"Aoi, you should go and greet Mr. Yamazaki too."

"It's Grandma!"

I was playing games yesterday until 2 a.m., and I'm a little distracted right now.

It wasn't until her grandmother reminded her that she hurriedly ran forward and followed behind Himeno Saki.

"Hello, Professor Yamazaki."

Himeno Saki walked to the front of the courtyard and greeted Yamazaki Kazukaze.

"Good morning, Saki-kun!"

Yamazaki Kazuka was taken aback by Himeno Saki's outfit today. Her prominent breasts pushed up her already cropped black short-sleeved shirt, and the way her breasts swayed as she ran was quite eye-catching.

[So Saki Ryo-san was wearing a chest binder a few days ago?]

Comparing the situation with Himeno Saki's a few days ago, Yamazaki Kazuka believes that this is the only possibility.

It has to be said that this outfit is really nice. Yamazaki Kazukazu feels a youthful vibe that only high school girls have, which comes with the early summer breeze.

Good morning, Professor Yamazaki.

Uesugi Aoi walked up to Yamazaki Kazukazu and greeted him politely.

"Didn't you sleep well last night?"

Seeing the dark circles under Uesugi Aoi's eyes, Yamazaki Kazuka guessed what had happened.

"Um, I..."

Uesugi Aoi immediately felt guilty.

"Let's go inside and talk."

Yamazaki Kazukazu's worst fears came true: Uesugi Aoi likely engaged in retaliatory entertainment last night.

Because she spends all day studying, Uesugi Aoi chooses to vent her frustration by playing games at night. If she has weak self-control, she can easily get carried away.

One problem after another. I'll just use the Hextech Gear I got yesterday on Himeno Saki.

The three entered the room, and while Himeno Saki was taking out her homework and test papers, Yamazaki Kazukata summoned the system.
