for Advance Chapter
My sister went out.
That doesn't mean she ran away from home. Today, while we were having lunch together as a family, my sister said she was going to stay over at a friend's house tonight.
It had happened before so Mom didn't suspect anything, but Airi didn't think so.
Because my sister was doing a fashion show by herself in her room. It seems like she was keeping it a secret, but if she was rummaging around in the next room, she was bound to notice.
You don't normally do that when you go to stay over at a friend's house.
Also, I caught a glimpse of my sister before we went out, and although she usually dresses up when she goes out, today she was dressed up a little. Like she was going on a date.
Suspicious. Very suspicious.
Recently, he's not just a nice guy with a strange face, but he seems to be getting along well with Someya-senpai. I'm very happy about that.
...…!! Huh? Wait, maybe Airi noticed?
Big Sis, aren't you secretly meeting up with Someya-senpai today?
She's worried about what other people think when she goes out at night. Since the announcement of her upcoming movie, she's been getting even more attention, and if she gets caught going out with a guy during the day, it'll be a big problem.
I was a little worried before, but I'm glad that things seem to be going well with Onee-san... No, not that.
"I'm curious to know how you're spending your time with Onee-chan and Someya-senpai."
As a younger sister, as a young girl of marriageable age...and as a woman who Someya-senpai loves.
"I should still be able to chase after my sister... Mommy, Airi, I'm going to the convenience store for a bit!"
Before hearing her mother's reply, Airi puts her feet into her sandals and rushes out of the house. Big sister, it's okay because we just left a while ago.
...Ah, found it!
I looked around and found a girl who looked a little excited. Okay, I'll sneak in without being seen.
I grew up seeing older girls who were always well behaved, so seeing an older girl like this is refreshing and fun.
As she follows her older sister, Airi thinks for a moment.
Airi is certainly rooting for Onee-chan and Someya-senpai's romance. But Airi also likes Someya-senpai. Those two seemingly contradictory feelings should be able to coexist...
After all, Onee-chan has always worked hard for Airi and the others. And Someya-senpai is the best match for Onee-chan. So Airi can't get in the way of that. There's no way she'd take away Onee-chan's happiness...
So Airi is happy just to have Someya-senpai, who has become good friends with her, play with her occasionally. It hurts a little, but... she can bear it.
Yes, I've decided. I was thinking that if Onee-chan doesn't choose Someya-senpai like before, then what will I do, but if she does choose Someya-senpai, then Airi will devote herself to supporting Onee-chan.
......While I was thinking about this, Onee-chan went into the park. And then...oh, it's Someya-senpai sitting on the bench. It was a rendezvous after all.
"Onee-chan and Someya-senpai look like they're having fun."
Someya-senpai noticed that Onee-chan was fashionable and complimented her. Onee-chan is embarrassed... hehe, Onee-chan is cute.
After talking for a bit, Someya-senpai and Onee-chan seemed to be going somewhere and walked out of the park, holding hands.
While I think that it's nice, I'm also happy that things seem to be going well between the two of them.
I follow the girls, who are walking happily together, for a little over ten minutes.
"Oh, I've been here before."
I wondered where we were going, and it turned out to be a nature park I had visited when I was in elementary school.
Is there something going on here? But there aren't many shops open at this time...or rather, if you're around Airi's age, you'll probably get turned away.
Someya-senpai and his older sister go further and further in.
......Come to think of it, this is the place that my teacher told me not to go to when I was in elementary school, so I couldn't go there.
Ah, I found a sign. I checked it with my smartphone's light and it looked like there was an observation deck up ahead. Wow, I didn't know that. ...Oh, I have to follow the girls.
We started walking again and walked a little further, and found the girls. It said it was an observation deck, so I guess they were enjoying the night view together. How romantic.
The girl who seemed to be fascinated by the night view turned to face Someya-senpai with great enthusiasm. That girl is really happy. There's no doubt about it.
Then the older sister deliberately presses her body against Someya-senpai.
"You're pretty bold, Onee-chan."
It was at that moment that Airi started to feel a little excited.
"Ah..."
The two figures became one.
"...Onee-chan and Someya-senpai are kissing."
Her heart felt tight. Intrigued, Airi's hands had tightened before she realized it.
"As expected... it's a bit spicy, I guess."
Being in love is good, but...
"Hey, why did you girls go that way...?"
After they finished kissing, the girls who had been talking went towards the overgrown vegetation.
"What happened?"
Feeling a bit skeptical, I followed quietly so the girls wouldn't notice.
