【★☆★Notice to the Readers★☆★】 In the afterword,

there is a very important announcement.

I hope you’ll read until the very end.

I came on a trip to Hokkaido as an escort for my high school girlfriend-sister, Nanako, who was attending an open campus event at Hokkaido University.

Then, my makeshift girlfriend and younger sister, Akari; writer Rushia; and my step-younger sister, Midori Lake, came crashing in because they got lonely.

The hotel we were staying at was apparently one of the hotels owned by the Hirata Kogen property group.

Upon learning that I was engaged to their granddaughter, the manager put us up in the most expensive room in the hotel...

“Whaa! Wow! It’s huge!”

Akari stated her impressions immediately upon entering the room.

It really was quite spacious. Looking at the hallway layout, I realized there were several small rooms within the hotel suite.

"Sister, look at this! There's an outdoor bath right outside the window! And it has jet jets!"

“...Whoa! That’s amazing, Akari-chan.”

High-energy juku sister duo. Nanae doesn't seem particularly bothered by the fact that Akari and the others came from Tokyo.

Well, if Nanae's happy about it, I don't see why I should care either. "Onii-chan," "O-oyakata."

Midori and Rushia lean in close. Their faces look unnervingly serious. "What's wrong?"

"Onii-chan, that... did you... sleep together?" "Sleep together is such a weird way to put it..."

It seems they're asking if he slept with Nanae.

Not literally sleeping, but rather an euphemism for sexual intercourse. "No, we didn't." "R-really...?" "Yeah."

Midori and Rushia let out a breath of relief.

"By the way, why are you relieved, Rushia? You're the one who did it with Onii-chan, right?"

"N-no, that's... well, it's just natural to be concerned about this!"

Rushia tries to maintain a mature air, but I think she'd actually be better off just goofing around with friends like this.

I feel that instead of straining to put on airs as the "Daughter of Hiraide," letting Nukaru's true self shine through would do her more good in the long run.

"What, what? What are you guys talking about-?"

「...So Akari's worries turned out to be groundless, huh.」

「! H-huh~... I see~...」

Akari broke into a completely relaxed grin and came over to sit next to me, poking my ribs with her elbow.

「Kararin-kun, you're all alone with such a beautiful girl like this~. Not even laying a finger on her? Looks like you're pretty pure after all, huh?」「No, it's not like that...」

「Exactly, Akari. You forgot your older brother already has one flower on the side?」

「Oh right! Aaah, why is me, who's been making moves constantly, always left for last?! Nnngh~!」

Seeing her squeal and make a scene, Nanae smiled.

I prefer it when Nanae is quiet, but she seemed happy to be able to have such a fun trip with her friends and little sisters.

It made me happy that Nanae was so pleased. 【★Very Important Announcement】 I posted a new short story! The title is,

『I Can Travel to Another World, But I Can Also Go Rambo in Reality? Living a Slow Life in the Countryside~ Falsely Accused and Fired at My 30th Birthday, I Find a Door to Another World at My Grandmother's Country House. Rampaging in the Other World and Doing Hobbies Without Working in Reality~』
