My Plain-looking Fiance is Secretly Sweet with Me Volume 3 - Chapter 8

Chapter 8
I think there’s a limit to my little sister's unfriendliness

“Uggh…, Yuu-niisan, why is Yuuka always mad at me?”

“…Erm, on the contrary, why did you think that Yuuka wouldn't be mad at you?”

After Yuuka present the school simulation between Sakata Yuuichi and Watanae Yuuka..., she became so embarrassed that at dinner, she wore a hat to cover her eyes and ate her dinner in silence.

At that time—this is what Isami said to Yuuka:

“Yuuka, could you please take off your hat? You see, your cute shy face is an interesting dessert to decorate dinner with...!”

Hearing those words, Yuuka became pissed off as hell at her.

As a result of Yuuka’s anger, Isami is now crying in her room at night.

Good grief, this kid should to take an objective look at her own words and actions.

“I just wanted to cheer up Yuuka and make dinner fun, though…!”

“If that's the case, then you should’ve said that. I think she's mad at you because you used that pick-up line way of speaking.”

“I told you, I can't do that… I've always been worried about Yuuka, so before I knew it I treated her like a child. That way of speaking was ingrained in me from my cosplay activities at the men's cosplay cafe. I’ve absolutely no idea how to fix it!”

Having a very unusual problem from my sister-in-law, I don't know what kind of advice I can give her.

Besides, I think Isami's sense in reading the atmosphere is a bit bad. When she showed the album the other day, I could understand that she wanted to show off Yuuka's cuteness, but in the end Yuuka got mad at her for pushing only pictures that looked like Yuuka’s black history.

...For some reason, she who like that looks like like Yuuka..., and maybe these two sisters are just as clumsy.

“Yuu-niisan!”

Isami raised her voice, and suddenly she grabbed my hand.

With her big moist eyes that looked like Yuuka's, she looked at me.

“Please, I want to be guided by Yuu-niisan who Yuuka loves so much!”

“Okay, okay, I understand…, but first can you let go of my hand? Have you forgotten that the other day Yuuka got angry seeing this kind of situation?”

“I’ll do anything you want as a form of my thanks!”

“I told you, don't use such a strange way of speaking! If Yuuka hears you talk like that——”

Just as I said that, bang,  the door opened with a tremendous momentum.

Then, from behind the door, the person who was looking at me with bulging eyes was——Nayu.

“I’ve heard everything…, I'll call Yuuka-chan.”

“Wait, Nayu, calm down, listen to my explanation first!”

Ignoring my words, Nayu ran to the second floor.

Then, after a while..., she came back carrying Yuuka who was rubbing her eyes, probably due to being forcefully woken up.

“Unghh…, what's wrong, Nayu-chan? My head is a little fuzzy…”

“Yuuka-chan, look at those two. There was an incident happening in this room!”

Before I could say anything, Nayu had already started to speak.

Then, she said something very outrageous.

“I saw it! Nii-san…, he did a night crawling to Isami.”

“Hmm..., HMM?! N-Night crawling?!”

Waking up from her drowsiness, Yuuka opened her eyes wide.

Beside her, Nayu shown an expression that seemed satisfied.

“Yuu-kun, what does all this mean?!”

“That’s my line! What do you mean by doing this, Nayu?”

“I'm just telling the truth!”

“What part of that is truth?!”

“Huh? Are you looking for an excuse? Just now I was clearly listening to lewd conversations like, [Please guide me like when you loved Yuuka], [Can you please let go of my hand first, in a situation like this...], [I’ll do anything!]”

“Don't interpret things based on half-assed information! That is slander, you know?!”

“Eww…, you really are a dangerous guy trying to make excuses like that! You tried to lay your hands on your fiance's little sister, and then you blamed your own little sister for the crimes you committed? It's a violation of my rights as a little sister!”

Gosh, why is every [little sister] in my family always being pain in the ass...

“Yuu-kun..., how dare you!” Believing in Nayu's delusional words, Yuuka exclaimed with a sullen face. “If you want to lay your hands on Isami—W-Why don't you just doing night crawling on me! E-Even I’ll do anything you want!”

“Are you aware that you just said something immoral, Yuuka?”

“I see…, so it's all about breasts, huh. Isami might have hidden them when she was cosplaying as a man, but she actually has big breasts, so you prefer big breasts, right?!”

“Sorry. If it's like this, I think I'll hate big breasts…”

“Fufu…, good grief, you're always too quick to jump to conclusions, Yuuka.”

As the situation got more and more complicated, someone who said something unnecessary interrupted us. She has black hair that is almost as long as Yuuka's, also wears glasses and has a face similar to Yuuka's. She is my sister-in-law, Watanae Isami.

“Yuuka, don't misunderstand. Indeed, I admire Yuu-niisan, but I'm like that because he loves you so much. There's no way I'll try to make a move on my brother-in-law who always supports you when I'm constantly worrying about you?”

“Wouldn't it be rude if you said that you were constantly worried about me? I’m your big sister, remember?”

“Therefore, if you think rationally, then in this case—it's obvious who's the real culprit, isn't it?”

Ignoring Yuuka's statement, with a fearless smile, Isami stared at Nayu.

Seeing Isami's gaze, Nayu suddenly glared.

“...What? Are you blaming me for this?”

“Don't be mad, okay? I can understand how you feel. You must be jealous because your dear big brother was taken from you, right, Nayu-chan?”

“H-Huh? Don’t kidding! I'm not jealous at all! There's no way I'd be jealous of this useless brother of mine!”

“Fufufu, your panicked face is cute too. Shall I give you a pat  at your head?”

“…How annoying is this idiot who likes to act with gentle man template?!”

Idiot who likes to act with gentle man template.

Those harsh words unexpectedly seemed to offend Isami.

“…Sorry, but can you correct your words? I'm a famous male cosplayer and the number one butler at the [Butler Cafe], you know? If it was just a template, I wouldn't be in such position!”

“So? Women who are captivated are just pathetic people who can't see reality, right? From my point of view, you’re just a cold person masquerading as a gentle man. Just because there are people who admire you, you get carried away, how shameless!”

“…I can't ignore those words of yours!”

The two little sisters glared at each other as sparks sparked between them.

And with that——

The [little sister war] between my little sister and my sister-in-law began.

---

The next morning.

Because of the mess that my two little sisters made, I slept too late and when I woke up it was already after ten.

In a daze, I walked down the stairs to the living room.

“Good morning...”

As I passed through the door to the living room, I found that I had entered [isekai].

“Fuhaa…, Nayu-chan, you're so cute~…”

“...Meow. I’m sister-in-law's cat.”

“……”

Sitting on the sofa, Yuuka had a very excited expression. On Yuuka’s lap, Nayu was rolling around while wearing a cat ear on her head.

Seeing that scene, the one whose cheeks seemed to be twitching was Isami.

...How did the situation turn out to be like this?

As for those cat ears, I think they are the cat ears that Yuuka wore when she did her previous cosplay show.

“…Nayu-chan, why don't you get out of Yuuka's lap right away? I think Yuuka is getting tired.”

“Tsk!”

“I'm fine! After all, Nayu-chan who is being spoiled is so cute...!”

“Meow.”

To me, the one who only know Nayu as a haughty girl, seeing her say, “Meow”, actually makes me feel that she looks scary rather than cute. Well, even so Yuuka seems to be very excited with Nayu being like that.

“I am sister-in-law's cat.”

“Kya! So cute~!”

“Hey, do you realize how embarrassing you are right now, Nayu-chan?”

“Tsk. At least I'm not as embarrassed as a girl who looks like a man, and thinks she's a famous person just because she's surrounded by women.”

“Uggh..., if it's like this...!”

Shocked that Yuuka was taken by Nayu—Isami left the living room.

Then, when she came back again to the living room...

“I guess I'll be Yuu-niisan's puppy?”

Isami, who since she woke up hasn't dressed like a man and wears glasses that make her look like Yuuka, wears dog ears on her head and a spiked necklace around her neck. On her butt, there was a tail.

In that appearance, with eyes that looked wet, she looked at me.

“What do you think, Yuu-niisan?”

“That's not funny at all, so I want you to stop doing that right now!”

“I don't do cosplay half-heartedly. Different from Nayu-chan's messy cat ears…, I've turned into a real puppy. I’m Yuu-nisan's pet, woof, woof.“

Saying something I couldn't understand, Isami suddenly hugged me.

The pressure from her huge breasts that was felt through my arms was really damaging my brain.

Aaah..., this must be the so-called brain killer...

“Disgusting, why are you clinging to my brother like that? Are you angry that I took Yuuka-chan from you?”

“Isn't it natural that as a family I get along with my brother-in-law? Or could it be..., you feel jealous because I snatched Yuu-niisan from you? You're so cute, Nayu-chan.”

“I'm not jealous. The jealous person here is you, Isami.”

“No, the jealous person is you, Nayu-chan.”

Nayu, who was wearing a cat ear, and Isami, who was wearing a dog costume, started a pointless fight.

Good grief, I'm so speechless at the behavior of these two.

“......Isami.”

At that time, lowered Nayu from her lap, Yuuka stood up from the sofa.

Then, with an expressionless face, she walked towards Isami who was hugging my arm,

This..., isn't Yuuka really mad at Isami?

“It's about time you received your punishment, Isami. You made Yuuka-chan very upset after all.”

Sitting on the sofa, Nayu smirked and agitated Isami.

Good grief, that girl really has a bad personality...

On the other hand, it seems that Isami also thought that she was in danger, so she immediately distanced herself from me.

Then, when Yuuka finally reached close distance with Isami——

——Gyuu.

Yuuka hugged Isami tightly.

“Eh? Yu-Yuuka...?”

“Actually I'm angry because you stick with Yuu-kun too much, but..., in the first place, I'm the one who keeps calling Nayu-chan cute. Sorry, Isami. It's a fact that Nayu-chan is cute, but..., you're cute too, Isami. You are my cute little sister.”

“…Yuuka.”

Isami was about to open her mouth, but she didn't say anything and just hugged Yuuka back.

Yeah, right, don't say anything.

If you spoke, you might end up detonating explosives without even using fire.

“...Tsk. Somehow it feels touching…, tsk.”

Putting her hands behind her head, Nayu stood up in a bored manner and tried to leave the living room, but I quickly grabbed Nayu's shoulder.

“…What is it, Nii-san? You’re going to lecture me? I don't want to hear a lecture from you.”

“No, it's not like that... erm,”

Looking at Nayu's lips that looked irritated, hesitatingly...,

I pat Nayu's head gently.

“Eh?”

Nayu's eyes widened.

Then, turning my face away from Nayu, in a low voice, I muttered,

“…Hearing what Yuuka just said, I was thinking that lately I've also been talking to Isami more often than you, right? You've always been rude to me, and well, I don't mind about that, but..., maybe you’re annoyed that I ignored you. I'm sorry...”

“Nii-san...”

When I said that while still patting her head, Nayu who rarely looked gentle——with a grin, she stepped on the back of my foot.

“Ouch?! You, isn't it too much to step on my feet with all your might...”

“You're acting weird after all! Are you an idiot? Don't get carried away! I don't care about that kind of thing at all!”

With a face that looked even redder than I've ever seen her, Nayu smacked my chest. Haah, that really hurts.

In the end, after going through all that...

“Alright, Isami, do you have anything you want to say to Nayu-chan?”

“…Sorry, Nayu-chan.”

“You too, apologize to her, Nayu.”

“…Sorry, Isami.”

At the insistence of me and Yuuka, for now the [little sister war] has ended.

I hope, in the future, these two little sisters of mine will get along more well with each other...

“As I thought, you like Yuu-niisan right, Nayu-chan? You'd be so much cuter if you were more honest.”

“Disgusting. Can you stop talking like that?”

“…Seriously, this is the first time a girl has been so harsh on me.”

“Tsk. I'm different from your cronies who can only say [You're amazing!], I'm the girl who will make you listen to my arguments. One day…, I’ll  definitely beat your tengu-like nose!”

Seeing them who started arguing again in less than five minutes, I couldn't help but sigh deeply.

It seems, not only to think about the relationship between Yuuka and Isami, but I also have to think about the relationship between Nayu and Isami.
