7pm.
I finished packing my things in my room.
At that moment, there is a knock on the door.
"Oniichan, it's dinner time!"
I heard Airin's voice.
Apparently she came to tell me that.
"Okay, I'm on my way."
I say, looking around the room before opening the door.
There was Airin wearing an apron.
And in her right hand she holds a rice scoop.
"Did you cook the meal?"
"Yeah. I was always the one making it."
"Well, what about Mom and Dad?"
"Both of them haven't come back yet." Airin says and goes to the first floor.
I followed Airin too.
Come to think of it, I was hungry.
There was a meal for two on the table.
Rice, miso soup, and salmon.
They all look delicious.
"Can I eat now?"
"Yes, please."
Airin said with her usual smile.
I take my chopsticks, pick up the salmon, and put it in my mouth.
...! Delicious!
I couldn't help but stare at the salmon.
"Delicious?"
Airin looks into my face and says.
"Oh my! How can you make something so delicious?" said Ryuchi with a glowing face.
I'll give my honest opinion.
Then he pops the rice into his mouth.
It was the first time I'd ever eaten something so delicious.
It might even be better than some high-end restaurants.
...Well, I've never been to a high-end restaurant.
Before I knew it, I had finished eating it.
I'm a small eater, so I can't believe I finished it so quickly...
"Oh, there's ice cream? Want some?"
"Ah, okay."
I forgot to be shy.
Well, we're family now so it's okay.
The ice cream that Airin handed me was a Ramune flavored popsicle.
It's just plain delicious.
"Oniichan, can I go to your room after this? By the way, we haven't exchanged contact information yet, right?"
"Yes. By all means."
Afterwards, we went to my room and chatted and played games.
After a while, I got a call.
It's mom.
"What's up?"
"Are you getting along with Airin-chan?"
"Yeah, I'm having fun."
"I see. Just because Airin-chan is cute doesn't mean you should lay a hand on her, okay?"
"I won't do something like that! We're family now!"
I say and hang up the phone.
I look at the clock and it's already 10 o'clock.
It's time to go to bed.
"Sorry, but I'm going to bed now."
"Oh, yeah. Good night."
Airin says this and leaves my room.
The next day....
"...Hmm..."
I wake up.
"Good morning, big brother!"
I hear a voice from next door.
The voice sounds familiar.
Despite my sleepiness, I try my best to open my eyes.
There... was Airin.
"...yeah?"
Is Airin here...?
I'm confused for a moment.
"...! Is this by any chance your room?!" I shouted with sudden rush.
"Oniichan, This is your room"
I look around.
Surely, this is my room.
The desk, the chair, and the books on the shelves are all mine.
So why is Airin here?
"...Airin, why are you here...?"
"It's a little sister's job to wake up her Oniichan, right?"
"What kind of job is that!? What time is it?"
"7 o'clock. Also, mom cooked dinner for us."
I tentatively sit up.
I guess I slept quite a bit...
"I'll be right there."
After I said that, Airin left.
I changed myself and went to the first floor, where food was already laid out for me.
I have no mom or dad.
"...Are Mom and Dad working?"
"Yeah, they just went to work."
I noticed Airin hasn't eaten yet.
It's like she was waiting for me.
"I'll enjoy having this"
As I said that, Airin and I started eating.
Noon.
I was eating the delicious ginger chicken that Airin had made for me.
"Oniichan, the entrance ceremony is tomorrow, right?"
"Entrance ceremony?"
"High school entrance ceremony!"
"...Ah, I remember now."
That's right, the high school entrance ceremony is tomorrow.
I completely forgot about that.
"Hey, what hairstyle do you think would be good tomorrow? Maybe the classic ponytail? Twin tails would be good, or maybe a side tail..." Airin asked with a bright smile.
"...Anything is fine."
"Well, I want you to decide, Oniichan!" Airin says while looking at me.
Even if you say that, I don't know anything about women's hairstyles...
"...By the way, what high school do you go to?" I asked while getting the glass to drink water.
"Kaedeno Gakuen High."
I spit out my the water from my mouth as soon as she said that...
"...Wait, you go to the same school as me!"
"What? You didn't know oniichan?"
"That's the first I've heard of it!"
...I can't believe siblings go to the same school...
"Show me what you look like in your uniform, Oniichan!"
"Tomorrow."
"Well, I think it's cool..."
"I'm not looking for coolness"
"Well, what if there's a test on the first day of school?"
I listen to Airin while drinking my miso soup.
"No, I can solve it normally though..."
"Are you smart? I don't know the difference between 'watch out' and 'look out.' Can you tell me?"
Wow, that's a pretty good question.
A lot of people don't really understand this, do they?
They both mean the same thing: "dangerous."
"Use 'watch out' when the object is clear. For example, don't use this when you want to say 'Watch out for that car.' Use 'look out' when the object is unclear. Use this when you want to say 'Watch out for the car and go play.'"
"Hey! You're so smart, Oniichan!"
"Oh, really? Even I didn't know that!"
Thus ended the events of the second day since I got a new step-sister.
