Hugging the World's Most Beautiful Younger Sister While Sleeping Somehow Turned Her into a Yandere - 07 - Having The Same Smartphone

“Nii-san, is your wrist okay?”

After school, as usual, walking home together, Runa looked at Aoi’s right wrist and asked. Since it was so painful to hold a pen yesterday, she must be worried.

“It still hurts.”

Although it’s a bit better than yesterday, the pain continues. Since it’s not a fracture, the pain should completely subside in a few days. Aoi planed to reapply the poultice when he gets home.

“Should we go to the hospital? There’s an orthopedic clinic nearby.”

Worried eyes were looking at Aoi.

“No, I won’t go. I have another place I want to go to.”

“Another place?”

“Yeah. I want to upgrade my smartphone.”

I’ve been using it for about three years, so the battery life is poor, and it works slowly.

The reason for the slow performance is that Runa’s audio files and photos are filling up the storage, but each of them is precious, so deleting them is out of the question.

So, I decided to change my smartphone.

“Smartphone… Since our parents aren’t here, you can’t change it without them.”

Minors need to have a guardian present or provide written consent to contract a mobile phone. With both parents away on a business trip, it’s not easy to change it casually.

“I’ve already contacted mom and received a consent form and a copy of her driver’s license.”

Aoi took out an envelope from his bag. Due to the sluggish performance of his smartphone for some time, he asked his parents for permission to change the model and received a consent form and a copy of his mother’s driver’s license. 

Since Aoi has a cash card in his mother’s name for transferring living expenses, there should be no problem changing the model. 

A student ID alone is not enough for a model change, but Aoi has a moped license, so there is no problem.

“If Runa wants to, do you want me to change yours too?”

Runa has been using the same smartphone for about three years, so Aoi got permission from both parents for her model change. Today, the weather is cloudy—fewer UV rays than on a sunny day— so there is no problem taking Runa with him.

“I’m fine with the current one. I don’t use it that much.”

Runa, who doesn’t have many friends, probably uses her smartphone for light internet surfing and watching videos. If she doesn’t use it that much on a regular basis, there’s no need to change it recklessly.

“Even though I went through the trouble of getting Runa’s residency certificate.”

“When did you get it?”

“I stopped by the municipal office the other day when I went shopping.”

Since Runa doesn’t have a driver’s license, additional documents such as a residency certificate are required for a smartphone model change. So, a few days ago, when I went shopping for groceries, I took the opportunity to get it from the municipal office.

“I understand. If Nii-san says so, I’ll change mine too.”

With a somewhat exasperated expression, she agreed, so Aoi took Runa to the electronics store.

“There are so many models.”

Having arrived at the mobile phone section of the electronics store near the station, Aoi was hesitating about which model to choose.

 Even if he had decided in advance, coming to the store made him feel tempted by various models. 

Aoi’s criteria for choosing a smartphone are color and capacity, with the two options being white, which matches Runa’s hair and skin color, and red, which matches the color of her eyes. 

Since the current one is white, the next choice is difficult between the two. 

The reason for considering capacity is to store many of Runa’s photos and voice recordings.

“Yeah.”

Runa is also looking at various models, seemingly having a hard time deciding. 

She didn’t seem to have any intention of changing her smartphone until a while ago, so it was understandable that she’s indecisive. 

The mobile phone section is not crowded on a weekday, and the staff glanced over them. They might think that the high school students holding hands and wearing school uniforms are just looking around without intending to change. 

The fact that a middle-aged woman who came a while ago was approached immediately, was proof of that. Whether the staff comes or not doesn’t matter much, so they don’t care much.

“I’ll choose the same model as Nii-san.”

“Is that okay?”

“Yes. I’m happy to have the same one as Nii-san.”

While holding hands, Runa, whose cheeks are red, muttered quietly while averting her gaze. 

Despite finding her as cute as always, Aoi is still indecisive about which one to choose. Even if they have the same model and color, changing the cover will make it clear at a glance whose it is, so the color can be the same.

“Do you have any preferences for capacity?”

Recently, all smartphones have good performance, so Aoi thought it would be better to choose one with a large capacity.

“Well… If possible, a large one. I want to save a lot of Nii-san’s photos…..”

Although the latter part was not very clear, Aoi nodded and called the clerk. They were able to change the model successfully, so they bought white and black smartphone covers and left the store.
