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 17: Landmine Duo’s Private Photo Session (Suggestive)

I invited two girls who are my best friend’s little sisters to my house, and they showed up in full-on landmine fashion… Seriously, why!?

And what’s more, they’ve neatly split into the mass-produced type in pink and the landmine type in black.

Are these two actually not on good terms?

“A-anyway, come on in, both of you.”

If they start fighting right here at the front door and the neighbors see it… some weird rumors are definitely going to spread.

“Is your mother not home today?”

“My parents both work full-time.”

“That’s right… Ryoya-senpai’s mother works at the counter of the central bank, and his father works at city hall. To think you don’t even know such basic information… Hmph, you still have a long way to go, Saito-san.”

“Kh…”

Mayana looked triumphant while Azuri gritted her teeth hard.

N-no, wait—on the contrary, why does Mayana know so much about my parents’ jobs!!

I haven’t even told that much detail to her older sister Maki, let alone Mayana!

“W-we made a promise to walk together from zero, teaching each other all kinds of things from now on. So unlike a certain half-hearted person who’s always hiding in her big sister’s shadow and doing nothing, we’re perfectly fine ♡”

“Huh? What’s that supposed to mean… Are you picking a fight?”

As if to prove it was the right call to get them inside quickly, the two of them started another mysterious heated argument even after entering the house.

I don’t really understand what they’re saying or why they’re fighting, but every time, it somehow turns into a clash over topics related to me.

“My room’s on the second floor. There’s really nothing interesting in it, but are you sure it’s okay?”

When I asked that, the two of them—

“It’s a treasure vault ♡”

“Same here.”

Their eyes sparkled intensely as they said it.

What’s that supposed to mean, are you trying to flatter me?

Well, I guess it’s better than them hating it.

“Here it is, my room. C-come on in.”

I opened the door to my room and let the two of them enter.

Then…

“So this is… Ryoya-san’s…”

“Ryoya-senpai’s… room…”

Before stepping all the way in, both of them reacted as if they had arrived at some tourist spot, pulled out their phones, and suddenly started pointing the cameras around the room.

“H-hey, wait, what are you two doing!”

““…………””

The chattiness from earlier was gone; the two of them began taking photos in complete silence.

Why do they need to take pictures!

There’s not a single unusual thing in here!

Are these two on a school field trip or something…

No, at this point it feels more like they’re investigating an accident scene.

Chapter 18: Yandere Battle [The Third Assassin]

Ever since they arrived at my house, the two of them have been acting really strange.

Well, they’ve been fighting nonstop since yesterday, so their behavior has been off the whole time…

“Why are you taking pictures of my room anyway? There’s nothing unusual here at all, and compared to Azuri’s fancy, spacious room, it’s just a normal room, you know?”

“Ryoya-san… no, it feels like a really nice room to me, and I was thinking that someday when I do a sketch, I’d really like to use this room if possible.”

“A sketch of a plain high school boy’s room!?”

“Ryoya-senpai… can I too?”

“Mayana too!?”

What kind of sensibilities do the girls from the white lily academy even have?!

“By the way, I’ve been thinking this ever since we came into the room.”

“Ah! W-wait, don’t tell me… does it smell bad?”

“No… actually, it has a really nice fragrance.”

Azuri said that with a surprised look on her face as she complimented me.

The smell of the room? Really…?

“This is definitely a room fragrance… and it feels like the kind of scent that’s typical of women’s brands.”

“Room fragrance? Oh yeah, now that you mention it, last year for my birthday, Maki gave me this… air freshener thing, I guess.”

I picked up the stylish bottle with sticks poked into the liquid that was sitting on my bookshelf.

I didn’t really know how to use it, so I just kind of placed it in the room after half-reading the instructions, but since it smelled nice, I left it alone ever since.

Lately I’d gotten so used to the scent that I barely noticed it anymore, but if it smelled good to the two of them, then that was lucky.

“Wow, I didn’t even know it had a fancy name like room fragrance. I’m really clueless about this kind of stuff.”

“………”

“Hm? Mayana?”

Mayana was staring really hard at the room fragrance I was holding.

“This… it’s the exact same brand that my sister uses in her own room.”

She muttered that and narrowed her eyes.

“Huh? Well, yeah, since Maki gave it to me. She uses it herself and liked it, so she gave it as a present.”

““…………””

Suddenly the two of them went completely silent and furrowed their brows deeply.

Hey, come on, what now?

Are they suspicious again about my relationship with Maki just because she gave me a present?
