Waking up to a morning just like any other, I sat up with a lazy feeling. I adjusted Nagisa’s arms and legs that were sprawled across my body back to a neat position and got off the bed. In the blink of an eye, I saw them return to their original position.
Seeing my hand moving on the empty bed felt a bit pitiful, so I tossed my pillow to it. It was adorable how it hugged the pillow tightly and fell back asleep comfortably. Yep, this is life.
I randomly threw on the pajamas that were sprawled on the floor and headed out of the room towards the kitchen. Along the way, I spotted two unfamiliar objects on the dining table. One was an ordinary shopping bag, and the other was…
“A box…?”
I felt a strange sensation from the unexpected object for a moment. But as soon as I saw the seal of Sanhaegyeong and the words “Yeondanbang” on the box, a hundred question marks popped up in my mind.
I’ve never bought or requested anything from Yeondanbang, so it must belong to Nagisa.
Did Nagisa really buy some defective medication from that ratty company?
Why? What on earth for?
Could it be that she has some health issues…? I need to check this out.
Well, it’s definitely not that I’m curious about the contents of the box. But if there’s a red flag regarding Nagisa’s health, I need to take care of my husband’s well-being. It’s something I absolutely need to know.
A frail attribute suspiciously being a shadow lurker is out of the question.
So let’s see…
“…?”
As soon as I opened the box, I was greeted by something that looked strangely like an X-Cast bottle.
[Rejuvenation Potion]
But hey, the name on the label looks pretty familiar.
If it’s the Rejuvenation Potion… then that’s the one, right? The potion that caused Sunohara Shun from Meihwa Won, the kindergarten of Sanhaegyeong, to live a day as Shuering.
…So why is this here, Nagisa? Am I the only one who doesn’t get it?
Let’s take a guess.
A. Nagisa bought it for herself.
Did Nagisa really go out of her way to get something like this for herself? I’d be more inclined to believe that I’m getting a love confession phone call from Rion right now…
B. She got it for me.
This seems quite plausible…
Setting aside whether I’d actually drink this right now, if I were Nagisa, wouldn’t there be a moment of greed to want this? It’s a bit galling to have obtained this without saying a word, but I can understand the sentiment.
C. Some other purpose entirely.
…Is there even a reason for that? Honestly, I don’t know.
Oh, there’s a manual at the bottom too.
“The effect lasts for about 30 hours… Individual differences can cause a deviation of about 6 hours… It is confirmed to roughly revert physical age by about 10 years, and there’s a regular customer who has requested resupply, so it’s reliable…”
So, who in the world bought this?
Personally… I wouldn’t mind either scenario.
“Oh, there’s one more line. It’s extraordinarily small…”
That ratty bastard wrote something along the lines of “If you can’t see it, it’s your responsibility!” in tiny print.
As I squinted to read through the details, it mentioned that there could be slight regressive effects akin to early childhood as a side effect.
…Reading this makes me want to feed it to Nagisa even more. Just imagining my normally composed and dignified Nagisa acting like a child, how can I possibly resist that?
Yet, since there’s also the possibility it was purchased for another purpose, I closed the box for now.
Then, glancing over at the shopping bag…
“Uuuh…?”
Clothes.
Clothes that… strangely resemble my school uniform?
It’s not exactly identical; instead of a shoulder cape, it has something that looks like arm warmers… and is this a T-party hat? At least on the surface, they look similar.
“Heueng… Nagisa-chan, so cute.”
No matter how you look at it, it’s an outfit prepared for me. That means that potion was also meant for me.
Could it be that she was planning to slyly feed me this potion disguised as something healthy? If she at least gave me a hint, it wouldn’t be so bad, but to get this without saying a word…
Hmm. That’s a bit annoying.
Even though this might be such a mischievous thought of slipping it to Nagisa while she’s in a drowsy state as morning tea…
Come to think of it, today is also Children’s Day, after all. Since most public holidays exist in Kivotos too, it’s not that surprising.
Hmm. Huuuum…
What should I do?
I took the clothes out and then opened the box again to pull out the potion. I rolled it in my hand for a moment.
I made up my mind.
Pon.
For something looking like an X-Cast bottle, the sound of opening it is rather amusing, I thought, as I brought the potion bottle to my lips.
A faint trace of reason was whispering to me, “That’s a concoction made by a rat! Are you really going to drink it? Have you lost it?!” but…
It’s really not my concern… No, I guess it is. But for Nagisa, what could I possibly refuse? I’m willing to go through a lot for not just Nagisa but also for our lovely kids.
Surely, none of them would misuse my feelings, right?
For now, it’ll last at most 30 hours… they said there’s a deviation of about 6 hours, so let’s assume 24 hours for this body. Therefore, by Sunday morning, I’ll be back to myself and the potion should wear off before the teacher comes to Trinity.
Yep, that’s completely no problem.
I tilted the bottle against my lips. With an inexplicable strawberry flavor, the liquid flowed into my mouth with a gulp.
As the potion naturally slipped down my throat, I savored the taste for a moment.
It wasn’t… bad at all.
“Uht.”
I felt a warm heat slowly rising throughout my body. A bit of pain spread through me alongside the steamy sensation.
After that brief surge of heat and pain subsided…
“…Ahaha☆”
My eye level had dropped just a bit… lower than the height of one head.
By the way, these pajamas are way too big and it’s all falling off…
In event stories, characters would automatically change their outfits. This must be game mechanics, huh, yep.
I didn’t have a bra, so I found my panties among the clothes prepared by Nagisa, slipping them on naturally.
One by one, after putting on the clothes, I didn’t have to go far to sneak a glance at my reflection in the living room TV.
“Fuhuh… so cute…”
I had seen this look before in albums Nagisa had shown me, but truly, just looking at it makes my breath catch in my throat because of how adorably lovely it is.
Yeah, at this point, it’s only polite to be honest. While I said it was for Nagisa, deep down, what I really wanted was to see this!
“Now then… is it time to surprise Nagisa… Hehe.”
Passing through the corridor with slightly smaller strides than usual, I entered Nagisa’s room.
Fortunately, it seems like Nagisa is still fast asleep… so all I have to do is snuggle into her embrace and wait?
Once I climbed onto the bed, I pulled out the pillow I had been using and occupied the space. Instantly, Nagisa’s arm naturally wrapped around me.
It ended up burying my face right between Nagisa’s breasts, but maybe because my body is younger now, I didn’t think too much of it. It just felt warmer and more comfortable than I expected… roughly that sensation. Yup.
Yup…
Should I sleep a bit longer like this?

What’s the first thing a person usually does when they wake up in the morning?
I’ve heard that people who sleep with their phones under their pillows often check the time first, but personally, I tend to place my phone somewhere else to avoid accidentally shutting off the alarm while I’m still half-asleep.
…Though in most cases, Mika-san wakes up before the alarm and usually shakes me awake, so it doesn’t make much difference.
Sometimes Mika-san goes out for the night, and on those occasions, I tend to wake up feeling a little gloomy. Even if I monopolize Mika-san now, I can’t keep enjoying this luxury forever.. Huh. I won’t think too deeply about it.
In any case, since those days have become the norm, the first thing I usually do when I wake up in the morning is to express my gratitude to Mika-san, who woke me, with a kiss.
But today, the alarm blaring loudly indicates that Mika-san must have spent the night out…
Wait a minute. That can’t be right; she shouldn’t have!
“Uuuh…”
“…?”
That’s odd.
The soft texture I feel under this arm and the sound I heard just now are clear proof that Mika-san is still on the bed.
Why, upon opening my eyes, is the first thing I see a pink wave burrowing into my side?
This is bizarre. Really bizarre.
Thanks to this, I couldn’t even think about turning off the alarm when I realized something else strange.
Has Mika-san always been this small?
No, that can’t be. It cannot be…!
“Nagisa-onee… turn off the alarm…”
Then, soon after, a peeking Mika-san’s youthful face caught my attention. Normally filled with twinkling stars, her golden eyes are looking up at me with half-opened eyelids.
Along with that, I heard a little girl’s voice with a tone slightly higher than what I remember Mika-san having…
Finally, I began to understand the situation properly.
“M-Mika-san…?”
“Nagisa-onee, hurry…”
“Ah, y-yeah…!”
…It seems that while I was asleep, Mika-san drank the potion I got from Sanhaegyeong’s Yeondanbang.
I had planned to coax her to drink it today, and now what is going on…?
