After returning home, I waited for about an hour, Miyuki came back, and then it looked like Mitoma-san had also come back a few minutes later as the doorbell rang.

I went to the door and opened it. But the one who showed up was a stranger.

“Hmm, so you are Kazuma Miyoshi huh…”

“Eh!”

I was so surprised by the sudden encounter with a stranger that my surprised voice leaked in shock.

The stranger approached me with a smirk and immediately went past me, heading up to the living room.

Who is this person? I got a LINE message from Mitoma-san earlier, so I expected her to show up at the door…but the one who showed up is a stranger.

She has black bobbed hair, ripped jeans and a T-shirt with a lot of exposure. Her body fits perfectly and you can clearly see her body line. Or rather, her chest is too big. She has a faint resemblance to Mitoma-san.

“… Sorry to disturb you~”

I couldn’t let this stranger come in any further, so I tried to stop her in her tracks. The woman intentionally fell and jumped into my chest.

“Hyah~!”

“Ugh… Stop!”

Squishy. Her big and plump b*****s pressed in my chest and a heavenly feeling transmitted to my mind, and suddenly my face turned hot due to embarrassment.

Too soft. How are boo-s so soft!

Wait, that’s not what I should be thinking right now! Who is this person in the first place? In any case, this isn’t the time for thinking about perverted things! Besides, Mitoma-sun isn’t here yet and I have to do something quickly.

“Uwa, so ecchi~”

“Stop—”

“Do you want to touch my boo-s that much?”

But my anxiety was short-lived as I heard a voice I knew really well from behind her.

“Onee-chan, what are you doing?”

“Ugh…Suzu”

“Hey, didn’t you say that you wouldn’t steal my senpai? Then what is this?”

“Well, it seems that Kazuma wanted to touch my boo-s really badly…”

“Eh!”

Then, Mitoma-san’s terrifying eyes were directed at me as she emmated a dark aura.

“Senpai, what’s wrong with you? Even though you already have me, you are hitting on my sister to the point you want to touch those oversized boo-s.”

She closed the distance between us as she directed that question to me.

So scary…

Her eyes looked really scary right now.

When she stared at me with those eyes that weren’t smiling, from a distance of barely about 10 centimeters away from me, I felt a chill run through my spine.

“Ah, no… well…”

Again, just like with my sister earlier, I couldn’t tell the truth and my words got stuck in my throat.

Mitoma-san looked at me with the same expression and tried to come even closer.

Just as I thought that I couldn’t take it any more, the onee-san tapped on her shoulder and said, “Suzu, stop it now.”

“Nee-san, why? But, senpai…”

“I’m just joking. Come on, stop scaring him.”

“—What, you were joking? Then, nee-san…”

“—It’s fine. Come on, he seems like a good, serious kid. Now, let’s go inside.”

The onee-san then pulled Mitoma-san away from me and dragged her further inside the house.

Apparently, she was her elder sister.

So that’s what she meant by the person she wanted to show me…

I don’t know what’s going on here at all.

Time passed and the onee-san cleared off the misunderstanding and after a long talk, Mitoma-san finally calmed down and was now acting as her usual self.

We were now seated at the dining table, curry and side dishes which were prepared by Mitoma-san were lined up, and the four of us surrounded the small table excitedly.

“Thank you for the food.”

We clasped our hands together in a gesture of gratitude and started eating the curry.

“It’s delicious!”

“Ehehe~… I tried my best. Thank you for the compliment. There’s more, so please eat as much as you want!”

“As expected of my little sister. It’s delicious”

While the two sisters were chatting happily, Miyuki and I progressed to eat our meal smoothly.

As we continued to eat, before I knew it, the contents of the pot were already over.

“Hah~… It was really delicious!”

“It was too tasty. Mitoma-san”

“No, no, it was my pleasure. I feel elated that my cooking suited your taste, Miyuki-chan.”

Mitoma-san was smiling happily when she was complimented on her cooking.

Mitoma-san’s onee-san poked her with her elbow and smiled mischievously.

I thought they looked similar in this regard, so was this habit of hers when she teased me everytime, inherited from her sister?

“It really was delicious, I would like you to make it again sometime.”

“Heh~ You are so smooth with your words. Perhaps you are aiming to get something from Suzu?”

“No, no… that’s not the case.”

“Onee-chan, it’s obvious, so stop saying it again and again.”

“Ahaha~ I see. You are too shy.”

She was endlessly teasing Mitoma-san and there was no end to it as she was really hopeless in front of her.

As I watched the two of them, Miyuki, who was sitting next to me, held her stomach while laughing and murmured.

“Wow, I never thought not only me but Suzune-chan’s sister would also come. It’s nice to have some fun like this!”

Indeed, I never thought Mitoma-san’s sister would come to visit us. I didn’t even think that the dates would overlap and due to it, I couldn’t prepare anything.

“Haah… If you had told me earlier that your sister would be visiting us, I could have prepared various things in advance.”

“There was no need for that. I just came here to take a look, I’m going to leave soon.”

“What, you’re leaving already?”

“Yeah. I have work tomorrow… it’s really busy during the Golden Week”

“Come to think of it, you work part time at a pub, right?”

“Yeah, that’s right. Well then, I’ll come again~”

Come to think of it, I wonder how old she is. She doesn’t seem like a college student though…

“Um, by the way, were you a college student?”

“Me?”

“Yes”

“Ah, I’m actually a graduate student. I was also in the science department.”

“Really?”

“Yeah. By the way, what department are you in, Kazuma-kun?”

“I’m in the engineering department… “

“Ah, then we’re different. I’m in the chemistry department of Science. Right now, I think I’m in the chemistry major course.”

“Chemistry… I’m not really good at it.”

“Haha. For me, physics is more difficult than that, you know?”

“That’s not true…”

As our conversation was smoothly progressing in a flow. A voice suddenly interrupted us from the side.

“Hey, onee-chan. Don’t take my senpai away from me.”

“Oh, sorry, sorry. I just got caught up in the flow of conversation.”

“Ugh! Why is it that just because I’m in the literature department, I am being left behind… Ah, that’s right, isn’t Miyuki-chan also planning to join the literature department?”

“Nope, I will also be joining the science department. I’m good at it.”

“Ughh—!!”

Unfortunately, our family members have always had good brains.

Mitoma-san, couldn’t bear the fact that she was being left behind, cried out and collapsed on the spot.

While watching her cute antics, we laughed out loud.

It feels like the beginning of happy days had just begun and for just a moment, I was able to distract myself from that unexpected reunion. That’s what it felt like.

<<Author’s Note>>

Although it’s becoming serious… I don’t think the relationship between the two of them will fall apart, so please don’t worry about it. I’m writing this now because I think it’s necessary to build their relationship from now on!

I think there will be a climax scene in the upcoming next 10 chapters!
