Hugging the World's Most Beautiful Younger Sister While Sleeping Somehow Turned Her into a Yandere - 25 - Studying For a Date Through Light Novels

“Why did you bring me to the bookstore?”

After school the day after they nearly kissed, Aoi brought Runa to the bookstore near the station.

It was drizzling, giving them an excuse to spend time together without raising suspicion.

Runa, curious because they rarely visited bookstores, asked with a puzzled expression.

“I wanted to get something.”

Taking Runa’s hand, Aoi led her to the light novel section.

He picked up several light novels with attractive heroines on the covers and began browsing.

This time, he wanted to choose a light novel that was very important to him, so he decided to select it in person rather than online.

“Since we’re going on a date, I thought I should study by reading light novels.”

As he held a light novel in his hand, Aoi spoke to Runa.

Despite being a serious siscon, he’s serious at heart. So he would never skip on preparations before a date.

Yesterday, he asked Keisuke for recommended date spots, and now he planned to study by reading a romantic comedy light novel that featured dates.

Light novels often depicted the protagonist’s emotions vividly, making them a valuable reference for dates.

“Why light novels?” Runa asked as she picked up a novel herself.

Runa also picked up a light novel.

Aoi couldn’t tell if she did it consciously or unconsciously, but she held a light novel featuring a silver-haired, red-eyed heroine on the cover.

“Simply put, because little sisters are the heroine.”

Although he doesn’t read them much, in romantic comedy light novels, whether the little sister is the heroine or not, they appear quite frequently. 

Of course, there are also works where they become the main heroine and even end up with the protagonist. 

He had spent his free time at school researching light novels where siblings go on dates, and now he was about to buy and read them from the bookstore… To come up with the perfect date plan.

“It’s a shame… there’s no albino heroine.”

She felt a surge of anger to the point where he wanted to crush the light novel with the silver-haired heroine on the cover.

While hair color is determined by the amount of melanin, born with silver hair would naturally mean sensitivity to sunlight and water.

But in these light novels, the silver-haired heroines swim in the sea or pool without issue and seem unconcerned about sunscreen.

Spending all day in the sea… it wouldn’t be surprising for someone with silver hair to get sunburned.

However, since light novels faithfully depict dating scenes, he still buys them.

“Isn’t that unavoidable? It would be difficult to develop a story with a heroine who can’t spend much time outdoors due to her physical condition.”

Runa said in a voice that sounded exasperated.

Certainly, making the heroine albino would mean missing out on important scenes like swimsuits at the beach or pool, which are crucial for readers. So, while setting the silver-haired heroine to be resistant to UV rays and water makes sense…

Since albino heroines are almost non-existent, he couldn’t help but think that having even a few would be nice.

Because if the heroine were albino, she would be even more beautiful and charming.

Looking at Runa, who is so beautiful with her hair, skin, and eyes, he couldn’t help but think so even more.

“No matter what character it is, they can’t be as beautiful as you, Runa.”

“Yes, yes.”

He said it with strong feelings, but Runa, who is often praised for her beauty, just responded casually.

“So, which one are you going to buy?”

“This one.”

Aoi picked up a light novel and showed it to Runa.

Many ecchi heroines appeared in it, and in this fourth volume, there was a scene where the protagonist goes on a date with his little sister.

Although he didn’t own any of the original light novels, he had watched the anime adaptation, so he was familiar with the story to some extent.

The anime was known for its fan service scenes catering to a male audience, featuring heroines often in their underwear from the first episode.

While there was a date scene with his little sister in the anime’s final episode, he discovered that many scenes from the original light novels had been significantly cut, as he found out from online research.

So, he had to read the light novel to get the full story.

“Is this the brown-haired heroine? Could it be that she’s the little sister?”

“Yeah, that’s right. She’s the one who goes around in a mini-skirt without wearing any panties.”

“What?!”

Runa seemed unable to comprehend the idea of not wearing underwear while wearing a skirt, and she exclaimed loudly in the bookstore.

She seemed surprised by the presence of an exhibitionist heroine in the light novel.

Given that typical light novels don’t usually include explicit sexual content, this light novel, which featured numerous perverted heroines, had certainly pushed the boundaries.

“Quiet down.”

“Oh, sorry.”

With the attention of the customers now on them due to Runa’s outburst, Aoi gently placed his finger on her lips to quiet her down.

It seemed that people assumed it was just a playful argument between siblings, as their attention quickly dispersed.

“Are you getting anything, Runa?”

“No, I’m fine. If we both start reading……. we won’t be able to stay together, right?”

When Aoi withdrew his finger from her lips and asked, Runa blushed and spoke in a sweet, pleading tone, looking up at him.

“Don’t say that here… Ugh…”

Even in a bookstore, hearing her sweet voice made Aoi feel weak. Although he had grown somewhat accustomed to it recently and wouldn’t collapse, he still needed Runa’s support to stand.

“Huh?… Nii-san?”

“I-I’m just… happy…”

After enjoying Runa’s warmth for a brief moment, Aoi purchased the perverted romantic comedy light novel.
