I ended up living together with the school's number one beauty who rejected me even though I hadn't confessed to her, but why are her beautiful sisters aiming to steal my virginity?

“—Why are you here of all places?”

A voice echoed loudly in the room, and I slowly opened my eyes. Before me stood Hiiragi Akane, with an expression that resembles closely to a demon.

“…..”

I couldn’t quite grasp the situation. Where am I?… And why was Hiiragi Akane in front of me?

“Ah!”

Looking at the beautiful long-haired girl sleeping next to me, I remembered. This is her house, and this room belongs to her sister, Shiemi-nee-san. And the current situation is very bad for me…

“I told you, didn’t I? If you enter our room, you will have to leave. Yet, breaking that promise the next day… You’ve got some nerve, huh?”

“…I’m sorry.”

“There is no use apologizing. What are you doing in Shiemi-nee-san’s room? Or could it be, did you do something strange to her when she was sleeping?”

“No, no! It’s not like that! I would never do such a thing!”

I stood up and hurriedly tried to explain.

“Then why are you in Shiemi-nee-san’s room? Answer me!”

“Well, you see…”

I couldn’t find the right words to explain yesterday’s situation, and I stumbled over my words.

“Well, it doesn’t matter. Whatever the reason, you broke our promise. No matter the excuse, that fact won’t change. So pack up your things quickly.”

“…..”

I wanted to say something in return, but I couldn’t find words of rebuttal. Or rather, I had indeed broken the promise, and any argument would be meaningless.

It was my mistake to fall asleep while being too engrossed in the game. So, I should just give up…

“What’s the matter? It’s so noisy in the morning… Oh, it’s you, Akane-chan. Good morning.”

Our voices must have been too loud, as Shiemi-nee woke up.

“Good morning, Shiemi-nee-san. …But, first of all, are you okay? Did he do something weird to you while you were sleeping? If he did, I’ll…”

“Oh. Nazu-kun… good morning. Last night was quite lively, huh? At first, Nazu-kun was a bit awkward, but gradually, he got used to it. I’m quite impressed as your onee-san.”

“I enjoyed it too. It became a good memory for me.”

“A memory? Nazu-kun is exaggerating. Oh, right. Nazu-kun, why don’t you skip school today and continue from where we left off yesterday? This time, I’ll show you my skills, an onee-san’s real skills…”

“Wh-What are you talking about, Shiemi-nee-san!”

Hiiragi Akane exclaimed as Shiemi interrupted her.

“What are you thinking about? We are just talking about a game.”

“…Huh?… Oh, yeah. That’s right. Yeah, I knew that. Talking about the first time, awkwardness, and skills. I won’t be fooled by such words.”

Well, she definitely misunderstood. But I better keep quiet; otherwise, I might be killed.

“Well, Shiemi-nee-san, it’s a shame, but Nazuna-kun won’t be able to play with you anymore. Because he’s leaving our house today.”

“…Eh? Eeeh! Why? I finally got a gaming companion! And he’s such a cute zombie! Why would he leave? Did I do something wrong? I’ll apologize, so please don’t leave, Nazu-kun!”

Shiemi-nee clung to me, hugging my waist tightly. It might look a bit erotic as her nightdress was still a little loose, but now is not the time to think about such things.

“Nazuna-kun isn’t to blame, Shiemi-nee. He broke an important promise. But… Nee-san, please release him.”

“…A promise? Is it about cup ramen?”

“No, it’s different. It’s about—”

“Do I really have to ask Akane-chan for permission every time I want to bring a friend here?”

“Well, that’s…”

“If Akane-chan thinks that everyone is important, she should understand that it’s my problem who I bring into my room. If Nazu-kun had forced his way in, that would be different, but he came because I invited him. So, it’s fine. I don’t want to kick him out. He’s a cute little brother!”

“…Even so, a promise is a promise.”

The two of them stared at each other.

“…..”

I couldn’t say anything amidst their heavy silence.

However, that tense silence was suddenly broken by a voice.

“It smells bad here~”

Touka-nee-san suddenly appeared, sniffing around like a dog.

“Oh, found it~.”

She pulled out yesterday’s cup ramen from the trash and looked at Shiemi-nee with faded eyes.

“What’s this doing here~? I want you to tell me the truth.”

“Wait! Th-That, Nazu-kun ate it. I didn’t know!”

“Really~? I’ve told you so many times, Shiemi-chan, you’re already unhealthy, so you shouldn’t eat things like this.”

“It’s okay. I didn’t eat it! He did!”

“Is that true, Nazuna-kun? If you lie, onee-san won’t forgive you.”

Touka-nee-san looked at me with an inquisitive gaze.

“Yes, she is telling the truth. I didn’t eat anything for the whole day yesterday, so I ate the Cup Ramen at midnight.”

“…..”

Touka-nee-san stared at me for a while with her bright beautiful eyes which made my heart flutter.

“I see… Thanks for your kindness, Nazuna-kun. I will forgive you this time. But, remember this… If you are hungry at night, then you can wake me up immediately, okay? I will make you something delicious to eat even if it is late at night. It’s a promise from your beloved sister.”

“…I understand.”

“Good. And Shiemi-chan, if you want to bring him to your room, just do it. But if something happens, you have to take responsibility.”

“Got it! I’ll take responsibility! Thank you, Touka-nee!”

Touka-nee-san nodded lightly, and Shiemi hugged me tightly again.

“Yay! Then let’s continue playing the game! Nazu-kun, today we’ll play all day!”

“Sure, let’s do that.”

“…Even though you broke the promise.”

Hiiragi Akane muttered with a sigh.

I sighed as well. Today was going to be another chaotic day.

Shiemi-nee, just a moment ago, easily betrayed me as if it were a lie.

“Yeah. Then, shall we go? Breakfast is ready.”

After patting my head, Touka-nee-san starts walking.

“Wait. Onee-san. My story is not finished yet—”

“No. We’ll have breakfast together. That’s a promise, right?”

“…Fine.”

Akane-san and Touka-nee-san’s figures disappeared from my sight, and then Shiemi-nee spoke in a voice that was fading away.

“It’s okay. Shiemi-nee also protected me.”

“Still, I’m glad…. I’m sorry, Nazu-kun. I got scared of Touka-nee-san and involuntarily betrayed you.”

“That’s fine. More importantly, let’s go eat, okay?”

I haven’t eaten anything since yesterday afternoon, and my stomach is already at its limit.

“Oh, right. You haven’t eaten anything since yesterday because you gave me that cup of ramen. …I’m sorry.”

“It’s okay. I don’t mind. Instead, let’s play games together again? Playing with Shiemi-nee was really fun.”

I lightly patted Shiemi-nee-san’s head and started walking towards my room.

“…Fufu~ That felt good.”

A light murmur escaped from her mouth faintly. However, those words don’t reach my ears.

◇◇◇◇◇◇

On the same day, during lunch break, Akane Hiiragi called a girl to the back of the school building.

“What’s up, Akane-chan? Calling me out to a place like this. Just so you know, I haven’t broken anything this week, okay?”

Not bothered by being called out by Akane, the girl—Kaede Hiiragi—swayed her neatly trimmed blonde hair to the shoulders.

“That’s not it. I have something to talk to you about regarding that guy… Nazuna Haimiya.”

“Nazuna-kun? Oh, the new little brother. Did something happen to him?”

“It seems like he’s up to something bad. So, Kaede, can you talk to him for a bit? If you talk to him your way, I think he’ll realize his mistake.”

“Hmm. So, talking to me means we’ll be throwing punches? If that’s okay, I’ll accept it. I’ve been curious about how strong he is anyway.”

Seeing Kaede cracking her knuckles, Akane smirked mischievously.

“Hehe~”

Kaede had won the national karate tournament in middle school. Although she quit the club after entering high school for some reason, she’s still a force to be reckoned with. Despite being a bit slow-witted and breaking things easily, whenever she got involved with troublesome guys, Kaede always resolved the issue easily.

So, thinking that this problem would be easily solved with Kaede helping her, Akane smiles triumphantly.

“I’ll kick him out of the house in no time.”

And so, unbeknownst to Nazuna, the situation moved forward to where he might be least expecting it.

[TL/N : Woah, I am curious how this will proceed. I am translating and reading this novel at the same time, so I am not aware how things will proceed, but I want to see how our MC will deal with her.]
