The mystery of how I had saved Anju-onee-chan during my Shota Era...
As if I didn't already have enough mysteries surrounding my own past, now a brand-new one had been added to the pile.
After that, Hiyori-sensei continued chatting amiably with my family. But once the conversation ended, she suddenly dropped a bombshell.
"But this house really brings back memories... Um, if it's alright, could I talk with Ryouta-kun in his room for a bit?"
"Eh? My room!?"
"We used to play in that 2nd Floor Room all the time, didn't we? Is that okay, Ryouta-kun?"
"Uh..."
"Don't tell me you've got something dirty hidden away in there?"
"I-I don't!"
Even as my older sister teased me, I immediately denied it.
It was true that I had one or two—or rather, about a hundred—questionable things in there... but admitting it out loud would definitely get me torn to pieces by Ryouta's Mother.
"Then shall we head up to the second floor, Ryouta-kun?"
"Uh... sure. But there's really nothing interesting up there."
"It's fine, it's fine. I want to see Ryouta's Room."
My room was covered in anime character tapestries and other embarrassing junk. Showing it to anyone was mortifying.
Still, if she really wanted to see it, I supposed it was okay...
I left the living room with Hiyori-sensei and stepped into the hallway.
"Hey, judging from your reaction earlier, does that mean there are erotic things in Ryouta-kun's room?"
"Th-there aren't!! What are you saying, Hiyori-sensei!"
"It's Anju-onee-chan, remember?"
"Ah... Anju-onee-chan."
This was bad. She had completely seized control of the pace.
At this rate, I was going to get utterly dominated by this twenty-five-year-old onee-san!
No, wait. It was still too early to panic.
"Um... Anju-onee-chan-san."
"What's with the 'onee-chan-san'?"
"No, it's just... about what you mentioned earlier. How I apparently helped you. What exactly did you—"
Right before we climbed the stairs, I asked Anju-onee-chan that question in the hallway. That was the exact moment it happened.
Ding-dong
The intercom rang while we were still in the hallway leading to the entrance.
"Looks like someone's here. Hmm, Mother and the others are still in the living room. Should I answer it?"
"It's okay! You're a guest, Anju-onee-chan, so I'll get it!"
In a slight panic, I hurried to the front door and yanked it open.
Whoever was visiting on a holiday afternoon like this had to be some pushy solicitor or a delivery person.
"Sorry for the wait... Hm?"
The instant I opened the door, an electric shock shot through my entire body.
"Fufu. Good afternoon, Ryouta-kun."
"...R-Rui!?!"
