My beautiful sister-in-law who is only attached to me, and my childhood friend who just made her high school debut, barged into my house?

Some time later.

In front of the TV in the Katsuragi family’s living room, the air was swirling with white-hot excitement.

“Look, there! Sho-chan!”

“Understood!…Gh!?”

“Sweet.”

“No way. How did you avoid that?”

“Damn, that way Mio!”

“I’ve got it!”

“Good job.”

“Oh, no, it’s an evasive.”

“Oh, no, it’s not gonna work.”

“Oh, no!”

The three of them were absorbed in the latest version of an action game they used to play when they were children.

The first time, they were enjoying the game in harmony, but Erika was unexpectedly, or rather overwhelmingly, strong, and before long, Shota and Mio were teaming up to challenge her.

They challenged Erika again and again, but never won, even though it was a two-on-one match, leading to Shota and Mio getting more and more impatient. Erika would lightly laugh at them, and they would feel provoked, so they would become even more heated.

They fought repeatedly, but in the end, they were unable to win a single match.

Eventually, Mio threw out her arms in defeat and fell to the rug carpet with a thud.

“Haa~, Eri-chan is strong. I didn’t have that image of you before.”

“I’ve been playing it for awhile. Besides, Mii-chan and her brother were also tough. It’s like you can read each other’s minds.”

“That’s because Mio and I often play together. We know each other’s moves like its the back of our hands.”

“Even so, we couldn’t even win a single match.”

“Always accept”

“Hey, stop your wriggling. You’re just like a kid!”

Mio flailed her arms and legs like a child.

At that moment, her skirt fluttered, revealing her pale white thighs which were usually hidden. Shota hurriedly looked away and sighed loudly while Erika smiled wryly at Mio’s shenanigans.

After Mio was done expressing her frustrations with her body, she jumped up vigorously and reached out her hand to Erika.

“Nn, but from now on, we can always have a rematch, right? Welcome back, Eri-chan.”

“Ah… yeah, I’m back.”

Erika was momentarily caught off guard, but she narrowed her eyes and squeezed Mio’s hand back.

There are many things I want to say.

But both my childhood friend and little sister are here with me, just like they were in the past. It’s the same atmosphere as back then.

I’m sure this is why Mio suggested that we all play games together. I loosened my cheeks as well.

“Anyway, Eri-chan has become too beautiful. Don’t you feel weird Sho-chan?”

“Wake up, you idiot! It’s my little sister.”

“No, you see, I think she can be more than just your cute little sister, besides ‘It’s okay even if we’re siblings, right?'”

“……?”

“Hey, Mio!”

“Hehehe.”

Mio brought up the lines from the previous day’s erotic doujinshi and laughed mischievously.

Seeing Erika tilt her head, Shota hurriedly raised his voice. When asked what he was talking about, he could not say that it was from an erotic doujinshi, and glared at Mio.

Then Mio, who remembered something, asked her while pouting her lips a little.

Ah, I told you to send me a picture of Eri-chan, right?”

“Uh, that’s… I’m sorry, there were a lot of things that happened and I forgot.”

I remember that I had made such a promise, but it turned out that Erika was not my real sister last night, and it completely slipped through my mind.

“Really… but I don’t blame you. I’d also want to keep such a cute little sister all to myself.”

Saying that, Mio hugged Erika tightly and rubbed her cheek.

Erika’s cheeks turned red as she did as she pleased.

When Mio saw this, she opened her mouth with a smug look expressing her envy.

“You’ll never be popular if you don’t keep your promises!”

“Shut up, I don’t want to be popular with my sister and childhood friend.”

“What’s with that? Don’t all the boys in the world want to be liked by their childhood friends?”

“That’s for those who don’t know reality!”

“Ugh, it hurts when you say that to me, even though I’m aware of it!”

Mio was so upset that she puffed out her cheeks.

Just then, I heard a growling sound.

When I turned towards the source of the sound, I saw Erika looking down in embarrassment.

The sunlight shining through the window had dimmed considerably, checking the time, I found out that it was past 4:30. It seemed that we had been engrossed in the game for quite a long time.

On the low table in front of us were the snacks I had picked out for lunch. Come to think of it, I hadn’t eaten much since this morning. When I became aware of this, I suddenly began to feel hungry.

It was the same for Mio as well as she rubbed her stomach and got up, heading for the kitchen.

“It’s a little early, but let’s have dinner.”

“Oh, do whatever you want why don’t you.”

“What in the refrigerator…”

Mio opens the refrigerator and checks the contents, mumbling to herself, “Cabbage, pork belly, bean sprouts …… and canned tomatoes,” as she goes about her menu planning.

It’s a familiar scene, but perhaps because of her girlish outfit today, I feel a strange stirring in my chest. As I shake my head to get rid of the fuzziness, I notice Erika looking at me strangely.

Ah, I see. Even if it’s the norm for me, it surely must be seen as unreserved behaviour, even though they are childhood friends. I chose my next words carefully to explain.

“After Erika left,…Mio lost her mother five years ago.”

“… what?”

“Things were rough for awhile and there were a lot of problems, but then we started spending a lot of time together. Then, mother started working until late at night, so we started making meals at home every now and then.”

“Oh…”

“Well, thanks to her spoiling me, my cooking sucks. How about yours?”

“It’s bad.”

“I see, we’re the same then.”

After saying that, Shota and Erika looked at each other and let out a bitter smile.
