The day after we fully enjoyed the summer festival.
In the end, I wondered if Riran and Noa really had become friends; today, they were studying for their entrance exams at our house under Riran's guidance.
Riran's way of teaching was easy to understand, even just looking on from the side.
As expected of someone with top-tier grades in her year. Both Kotono and Noa looked satisfied.
...Well, that's fine and all, but.
"Why are you guys studying at my place?"
"Oh, come on, Onii. This is the easiest place for everyone to gather, so it can't be helped."
"It certainly can be helped. You could just go to the library."
"The library is far, and we can't talk there."
Ugh... True. With Riran, a current Gingko High School student, teaching them, they wouldn't be able to talk in a library.
Even so, why at my house...
As if reading my thoughts, Riran spoke up.
"We can't talk in the library. A cafe costs money. If we went to my house or Noa-chan's house, one of us would feel like we have to be too formal. In that case, isn't this familiar house the place where we can relax and study the most?"
I kind of get that feeling too.
But, even if one is a relative, the reality of having a current high school girl (an absolute beauty) and a current middle school girl (an absolute beauty) in the house does not leave my mind at peace.
Even setting that aside, until just the other day, Riran and Noa didn't get along.
That alone made me quite anxious... but seeing them like this, it seems like they're okay.
"...Alright. Then I'll be in my room. Call me if you need anything."
"Got it."
"Senpai, see you later~"
"I can't concentrate when Onii is around, so just go already."
Kotono-chan, aren't you being a bit harsh?
With my drink and some snacks in hand, I moved from the living room to my own room.
Just then, the smartphone in my pocket vibrated.
Who is it... wait, a message from Riran?
Riran: Come to think of it, about that reward I mentioned the other day.
Reward? ...Ah, right. Since I let her bring Kotono and Noa to the summer festival, she had pestered me for a reward in exchange.
Akito: Yeah, what do you want? As long as it's something I can do, anything is fine.
Riran: Then, let's go to an amusement park. There was a place I wanted to go.
...Going to an amusement park is the reward?
In other words, she wants to redo our date with just the two of us?
What a sweet request...
Akito: Got it. When should we go? Tomorrow is fine too.
Riran: Let's make it three days from now. Meet in front of the usual station.
Akito: Roger.
Three days from now, huh. I wonder why it's not tomorrow or the day after.
Does Riran have plans? But I haven't heard anything about that... Hmm?
◆
And so, three days later. Wearing slightly stylish clothes and easy-to-move-in sneakers, I headed to the station.
And, as usual, Riran had arrived first.
Even so, I made sure to arrive ten minutes early... Just how long has she been waiting?
"Sorry, kept you waiting."
"No, I didn't wait long."
Looking closely, today Riran was wearing three-quarter length pants, sneakers, and a sleeveless top—a casual outfit that was easy to move in.
Since we're going to an amusement park today, I guess she went with clothes that are easy to move in.
"What's with that intense staring?"
"Eh? No, I just thought your atmosphere was different from usual. ...It suits you."
"A-ah... thank you."
Yeah, it suits her. It suits her way too much... but.
Because of the thin, tight-fitting sleeveless top and the pants that showed off her body lines, she looked overall erotic.
I saw her in a swimsuit at the sea recently... but I feel a different kind of clothed sexiness compared to the swimsuit.
Plus, because of the shoulder bag worn diagonally, it's creating that 'belt between breasts' look... emphasizing all sorts of things, making it hard to know where to look.
I see, so this is clothed sexiness...
"Akito, are you thinking about something stupid again?"
"I-it's just your imagination. More importantly, let's get moving."
"...Right. Then let's go."
We entered the station platform and waited for the train.
Oh, come to think of it.
"I haven't been told the name or location of the amusement park we're going to today, so where is it?"
"It's a surprise for when we get there."
"A surprise..."
"Now, now. Just look forward to it."
...If Riran says so, I guess I shouldn't worry too much.
But if that's the case, I only think of bad things.
Japan's longest haunted house, Japan's number one roller coaster... if I'm taken to a place like that alone, I feel like I'll collapse from physical and mental exhaustion.
Is she actually still angry about the thing with Kotono and the others...? No, no, Riran wouldn't... surely...
No good, I'm getting nervous and anxious.
"H-hey Riran. A hint, can you give me at least a hint?"
"What's this, are you that curious? Could it be, you're so excited you can't settle down? Good grief. Akito, you have a bit of a childish side, don't you?"
Grin, smirk.
Ugh... it's irritating to be thought of that way, but...
"W-well, yeah."
"Hehe. Since I'm always the one getting flustered, today you should be the flustered one, Akito. I'm not telling~"
Blegh. Riran stuck her tongue out slightly, and immediately after, the train pulled into the platform.
Now I'm even more worried... where exactly am I being taken, me?"
