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

Despite a slight hesitation in her heart, Uesugi Aoi chose to continue with her wicked plan.

After learning how to install and use the miniature camera, Uesugi Aoi took out a bottle of sleeping pills from her desk drawer.

I brought this bottle of sleeping pills with me; I've suffered from severe insomnia since junior high school.

Although doctors do not recommend taking sleeping pills at such a young age, it is the only one that allows me to fall asleep peacefully.

A dangerous plan has been going through Uesugi Aoi's mind over and over again these past few days.

Himeno Saki Ryo drinks milk every night, and I put four sleeping pills into her milk.

This guy would sleep until noon, then sneak into her room in the early morning to install a miniature camera hidden in her bookshelf.

There were dolls, books, and other random things there that she wouldn't find, and her grandmother wouldn't recognize either.

After the miniature camera was installed, I woke her up again, and as usual, nothing happened.

Wait for a suitable opportunity, then take a day off to let the two of them be alone in a room.

The best time to do this is when Mrs. Hime is not at home. She is a very busy person and is often not at home. It is a good opportunity to wait for.

Himeno Saki seems to really like wearing revealing clothes to entice Yamazaki-sensei's attention.

If she were left unchecked, she would definitely do something even more extreme.

All of this will be recorded by his miniature camera and then handed over to Mrs. Himeno.

My wife will definitely stop the tutoring after she sees it, and then I'll be free.

"Are we really going to do this?"

Looking at the miniature camera on the table, Uesugi Aoi muttered to herself.

Her conscience and cowardice made her hesitant to carry out the plan.

Ring ring, a cell phone rang.

Uesugi Aoi answered the phone.

"Aoi, do you have time? The coffee shop is short-staffed lately. If you're willing to come, the salary is negotiable."

"Oh, I'm sorry, I don't have time right now."

Uesugi Aoi really wants to work at a coffee shop; she is a woman with deep-seated materialistic desires.

When I'm in a bad mood, I relieve it by buying things.

"There's nothing we can do about that."

"Wait for the store manager. I might have time in a week or two."

"We'll see when the time comes."

A surge of hatred welled up in Uesugi Aoi's heart as she hung up the phone.

My perfectly good summer vacation was completely ruined by Himeno Saki. I was supposed to stay in my bedroom and sleep until I naturally woke up, go out to work at the maid café at noon, and come back home to enjoy playing games in the evening.

Now, instead, I've been dragged to this godforsaken place and am spending the entire summer in jail.

Driven by boundless hatred, Uesugi Aoi poured out four white pills from the medicine bottle. Seeing that the time was almost up, she prepared to carry out her plan.

"Grandma, are you delivering milk to Saki?"

"Yes. And yours too, you like to drink hot milk, while Saki likes to drink iced milk."

"I'll deliver it."

"No need, I..."

Before Grandma could refuse, Uesugi Aoi snatched the plate away.

"Grandma, go and rest."

"Okay, I understand."

Grandma nodded, knowing it was her granddaughter's filial piety, and didn't stop her.

Bang, bang.

"Saki-kun, I brought you some milk."

Uesugi Aoi knocked on Himeno Saki's door.

"What are you doing here? Come in."

Himeno Saki, who was hunched over her desk, asked with some confusion.

The moment the door opened, Uesugi Aoi's mind went blank, her body trembled uncontrollably, the plate in her hand shook, and the milk in her glass almost spilled out.

"Aoi, what's wrong?"

Himeno Saki turned around from her chair and saw Uesugi Aoi acting suspiciously. Her suspicion turned into wariness.

"Saki-kun, I'm fine."

Uesugi Aoi gritted her teeth to appear less nervous, picked up the iced milk in her hand, and handed it to Himeno Saki's cold noodles.

"Why are you the one delivering it?"

"I saw that Grandma was working too hard, so I took the initiative to deliver it."

Uesugi Aoi's forehead was covered in cold sweat.

"So that's how it is."

Himeno Saki picked up the cup somewhat embarrassedly, but her gaze toward Uesugi Aoi grew increasingly suspicious.

What happened a few days ago is still fresh in my mind. I wonder if this guy is up to some crazy idea again.

Himeno Saki had a sudden inspiration. She put the iced milk back and then reached for the hot milk on the plate.

"Saki-san, this is mine..."

"I've changed my mind. I want warm milk tonight."

As Himeno Saki Ryo spoke, she began to blow on the thin film on the surface of the hot milk.

"Then, I won't bother you anymore."

Seeing that the plan was not going to succeed, Uesugi Aoi wanted to get away.

"Don't go. Drink this glass of iced milk right in front of me."

Himeno Saki Ryo said as she drank.

"Saki-kun, are you afraid I'll poison you?"

Uesugi Aoi forced a smile onto her face.

"Drink it quickly!"

It seems that her yakuza bloodline has awakened. Saki Himeno speaks with a Kansai accent that sounds like that of a yakuza boss from the 80s or 90s.

"I get diarrhea if I drink cold drinks."

"Then I'll call the family doctor right away and have this glass of iced milk sent for testing."

Upon hearing this, Uesugi Aoi was utterly devastated. If she drank this glass of iced milk and took four sleeping pills, she definitely wouldn't wake up tomorrow.

If they take him to the hospital for a checkup, the truth will definitely come out.

But if she doesn't drink it, and Himeno Saki's family doctor finds that the milk contains sleeping pills, she'll be doomed.

Seeing Himeno Saki pick up her phone to call the family doctor, Uesugi Aoi immediately grabbed the glass of iced milk and drank it all in one gulp.

"Saki-kun, you see? I didn't do anything to hurt you."

Uesugi Aoi smiled, opened her mouth, and stuck out her tongue. White spots stained her pale red tongue.

"If that's the case, why were you so nervous just now?"

Himeno Saki was a little embarrassed. She finished her milk and put it on the plate.

Get some rest, see you tomorrow.

Uesugi Aoi didn't answer Himeno Saki's question, but instead hurriedly went downstairs with the plate in her hand.

After washing and arranging the cups neatly, she made herself a strong cup of coffee.

Having taken the medication myself for two years, I am very clear about its effects.

Normally, one sleeping pill is enough for me to sleep soundly through the night, but four sleeping pills are enough to keep me asleep for a long time. Tomorrow's alarm clock definitely won't wake me up. Once Himeno Saki notices something amiss, she will definitely call someone to check on me, and then the truth will be revealed.

The only solution I could think of was to drink coffee and force myself to stay up all night.

Back in her room, after taking a sip of bitter, strong coffee, Uesugi Aoi took out her PS5 and prepared for her all-nighter plan.

The strong coffee must have worked; two hours later, she not only wasn't sleepy, but she was actually getting more and more energetic.

This brought some comfort to Uesugi Aoi.

The phone rang, startling Uesugi Aoi.

She picked up her phone and saw that it was a call from Yamazaki Kazukazu.
