How I Ended Up with an Extreme Yandere Landmine Beauty When I Asked to Hang Out with My Best Friend's Sister to Get Better at Talking to Girls - Chapter 4-5

Chapter 4: The Yandere Finally Goes Dere?? The Truth About That Day??

I still had no idea what “that day” was about, but I kept talking with Azuri while sipping my frappé.

I decided to ask Shinichi and Maki at school tomorrow if they had any clue about that day.

For now, I needed to focus on keeping the conversation going with her.

Unlike earlier, sitting alone with her in this quiet café made me unsure what to talk about…

For starters, I figured I’d ask some of the things that had been on my mind.

There was still a lot I didn’t know since we’d just met.

“Um, Azuri-chan—”

“You don’t need the ‘chan.’ Please just call me Azuri. That makes me happier.”

“Huh? Oh, okay. Then… Azuri?”

“Yes♡”

Azuri’s voice suddenly brightened.

She preferred being called without the honorific? Was that even a thing?

She’d said she’d teach me everything about girls from top to bottom, but I couldn’t help feeling skeptical.

Worrying about it wouldn’t help, though. Time to get back on track.

“You’re a student at Yuri ga Oka, right? The fancy all-girls school.”

“Yes, that’s right. I actually wanted to go to a co-ed high school like my brother and you, Ryoya-san… but my parents were really strict about it. I’ve been at Yuri ga Oka since elementary school.”

“Since elementary!? Whoa, that’s something.”

So Azuri really grew up surrounded only by girls?

If that was the case, it wouldn’t be strange for her to have been in love with her first crush for eight whole years.

“But I don’t really like Yuri ga Oka Girls’ Academy that much. Everyone comes from good families and acts all high and mighty, their speech is so stiff, and they don’t understand my fashion sense at all.”

Fashion sense…

She meant things like this pink sweater or the ribbons in her twintails?

It did kind of look like mass-produced landmine-girl style.

“Hey, Ryoya-san, don’t you think that’s awful? I’m trying so hard!”

Azuri hurled that complaint—like a bomb—right at me.

Uh, what was I supposed to say here…

“I-I don’t know the full story, but… maybe some of it is jealousy because you’re super cute? Like, if I were your classmate, I’d probably be jealous.”

After all, I felt pretty jealous of how tall and handsome her brother Shinichi was.

I told her that while thinking about it.

“…Ryoya-san.”

“Huh?”

Azuri turned her face away and muttered softly.

Oh no… did I say something weird again??

“S-stop saying ‘super cute’ out of nowhere like that!”

“Out of nowhere?”

“It’s so sweet it makes my face feel like it’s on fire!”

“Face on fire!? Uh, sorry, I don’t really get it, but do you need a handkerchief?”

I quickly pulled one out, and Azuri took it right away.

“Eh…? Can I really have this handkerchief?”

“Well, I’d like it back tomorrow.”

“Thank you! I’ll treasure it forever! My face is hot today, so excuse me!”

“Wait, tomorrow you have to re—”

Azuri grabbed the handkerchief, picked up her frappé, and just walked out of the shop.

“Sigh… girls are seriously hard to understand…”

I had a feeling this was going to be tough.

—The next day.

When I got to school and walked into the classroom, Shinichi was already sitting at my desk, talking with Maki.

“Oh, it’s Ryoya! Morning!”

“Morning my foot. What was that about yesterday?”

“Ahaha! Pretty surprising, right?”

“Yesterday? What do you mean, Ryoya?”

It seemed Maki didn’t know anything yet and asked me about it.

No choice, I’d explain.

“After school yesterday, Shinichi introduced me to a girl, but the girl he introduced turned out to be his little sister Azuri.”

“Eh? That Azuri-chan? Hey, Shinichi! You seriously introduced your own sister to Ryoya?”

“Well, Azuri doesn’t have a boyfriend, and she’s asked about Ryoya a few times before, plus she already knows him, so I figured they might be a good match.”

“What kind of thinking is that!?”

Shinichi got scolded by Maki.

She was right, though.

But more importantly, I needed to ask about “that day.”

“That’s not the main issue, though. Azuri kept saying this was the first time we’d met since ‘that day.'”

“That day? Huh? Ryoya, did you talk to Azuri-chan before yesterday?”

“No, I don’t think so. She’s been at Yuri ga Oka since elementary, right? We shouldn’t have any school connection at all. Hey, Shinichi, do you know anything?”

When I asked Shinichi, his brows furrowed.

“Yeah… If there’s any connection between you and Azuri, I do have one idea.”

“You do!?”

Even though he was an outsider, he remembered something before I—the person involved—did.

“Yeah… Remember when we were in elementary school? That ‘summer festival’?”

“”S-summer festival??””

Chapter 5: Side Niijima Azuri “The Truth About That Day” (Azuri’s Perspective)

After reuniting with Ryoya-san for the first time in eight years, I returned to the dormitory at Yuri ga Oka Girls’ Academy.

My room was in the White Lily Hall, a dorm with only single rooms reserved for the top-performing students in the high school section.

My room was the one at the very end of the hall.

The moment I stepped into my proud room surrounded by pink fancy goods, all the tension left my body. Overwhelmed with joy, my knees buckled and I collapsed to the floor.

“Ah… I really… got to meet that Ryoya-san…”

Until now, I had never had a “chance.”

A chance to get close to Ryoya-san.

In my strict family, the rule was that I—as a girl—was not allowed contact with boys from other families until I became an adult.

That was why I had been sent to an all-girls academy since elementary school, and there was even a rule that my brother could only invite friends over when I wasn’t home.

Because of that rule, my brother almost always went to Ryoya-san’s house to hang out and never brought Ryoya-san to ours.

Once I entered middle school, I moved into the academy dormitory, and my days became nothing but going back and forth between the school and the dorm.

Some students went to lessons after school, so we were allowed to go out until curfew… but I never had the courage to go outside and talk to Ryoya-san.

But today, all that came to an end.

“Since ‘that day’… I’ve been waiting for this moment the whole time. Ryoya-san.”

That day… it happened when I was in second grade.

I snuck out of the house and went to the local summer festival.

I was supposed to go with my parents, but their work ran late and they weren’t coming home. Worried the festival would end before they arrived, I panicked and slipped out alone.

But once I was actually outside, I had no idea which way to go…

Standing all alone in the bustling festival grounds, someone running from behind crashed into me. I fell face-first and got hurt badly.

Blood streamed from my forehead. It hurt, it scared me, and tears were about to spill over.

I was at my limit… That’s when it happened.

“Are you okay? Are you lost? I’ll take you to where the adults are, so come on, can you stand?”

The one who helped me as I sat on the ground was Ryoya-san.

At the time, he had apparently gotten separated from my brother and the others and was looking for them alone.

Ryoya-san quickly wet his handkerchief at a nearby park and tended to my wound.

It was my first time interacting with a boy my age who wasn’t my brother, so I was on guard and couldn’t say a word the whole time. Even so, Ryoya-san cheered up my sullen self with all kinds of stories.

After that, he walked me all the way to the festival’s information booth where the adults were gathered.

And at the very end…

“Oh! Here, cover your face with this so the injury doesn’t show. It’s brand new and unused. You can have it.”

He gave me a fox mask from one of the festival stalls to hide my face.

He was kind, thoughtful, and caring all the way through… To the me back then, he was like a gentle big brother. I fell for him in an instant—so much that I even asked his name at the end.

Even now, that mask is displayed in my room… It’s my treasure.

“And today too… fufu.”

I sealed the handkerchief he gave me in a vacuum pack, then opened it over and over to enjoy his scent.

This is Ryoya-san’s scent now.

Ryoya-san’s handkerchief… haa, mm.

“Ryoya-san… mm, Ryoya-san… mm…”

I skipped dinner entirely and welcomed the morning still lying on my bed.
