On the second day, it was the day Agelia and I had agreed to go to the hot springs together.

Since it was a vacation, I thought she would dress more casually to pick me up, but... she was still wearing that starry magic robe and pointed magician's hat.

But I couldn't say anything about her because I was still wearing a maid uniform.

She looked at me with a slight surprise.

"Fir, are you going to walk with me in that outfit?"

"Well, we have to change into swimsuits when we get there anyway." I smiled shyly, thinking that my courage was really growing. Now as a boy, I even dared to wear women's swimsuits outside.

"Oh, you already have your swimsuit ready? That's good. I told you, Fir, you don't have to lack confidence. When I was fifteen, I was just like you, and I was only 1.5 meters tall."

I didn't know how to respond to her words. Does being the school principal have a hidden effect of "quickly becoming an adult"?

"So you will also grow up." She hugged me. "Shall we leave now?"

"Yeah..."

I glanced unintentionally at the gate and had a thought of not wanting to leave the hero alone in the manor for a whole day. But she should be able to take care of herself for just one day, right?

"Is the place we're going far?" I asked Agelia.

"It's quite far. It takes several tens of minutes even with my magic."

"Several... tens of minutes? In another country?"

I took out a hair tie and tied up my hair quickly in case it gets messy during the teleportation process.

"Let's go then."

As she gave the order, I quickly closed my eyes and felt like I turned into a gust of wind, the thrilling feeling of my heart beating faster was something I couldn't get used to no matter how many times I experienced it...

...

...

...

After a while, I arrived at a hot spring inn at the foot of a mountain on the border of the kingdom. Agelia often travels around and occasionally discovers interesting places. This hot spring inn is one of them.

Agelia acquired the room key from the bar hostess and did not give me one, instead she took me straight into the room. I stared at the double bed, feeling mixed emotions.

"The rooms in this inn are quite tight, so we'll sleep together tonight." - Agelia seemed to intentionally validate my thoughts and said this.

"Sleep together...?"

If it were two girls sleeping together, it would be nothing, but I'm a boy... even though I'm still underage, I'm not a little boy of four or five years old anymore.

I couldn't help but worry if the sleeping gown I brought was safe enough or if there would be any flaws exposed.

I saw her take off her magician's hat and hang it on the coat rack, then she casually flicked her waterfall-like black hair, and a wisp of fragrance wafted over.

Her hair is really well-maintained.

I remember when she was 1.5 meters tall, her hair had just reached her shoulders.

"Hmm? Fir, are you looking at me?"

"I think you take good care of your hair." I quickly said.

She chuckled, smiled, and flicked the end of her hair, looking like a big sister.

"Because I use magic to blow-dry my hair after washing it."

She demonstrated by spraying a gust of wind from the palm of her hand. I had nothing to say; I could only dry my hair near the fireplace each time I washed it, which couldn't compare at all.

"Sister, are you a plastic magic magician? I see that your magic is released in the form of wind."

Actually, I was asking on behalf of Lienchi, because she asked me if Agelia is an enchanted magician.

Lienchi - that's the name of the hero.

Only I know.

"As a magician of my level, it doesn't matter what type of magic it is. But you - you guessed correctly."

She blinked, smiled, and made a gesture of shooting a gun with her hand.

"Wind magic is indeed my specialty."

"I'm the principal, you know? I'm not usually this unserious in front of other students."

"Of course, you're my little sister after all."

As she said that, she took off her magic robe in front of me, revealing her perfect figure.

"What, what are you doing?"

Seeing her continuing to undress, my face suddenly turned red.

"I'm changing into a swimsuit, of course. Aren't you going to change, Fir?""I... "

I hesitated, watching her unbutton the first row of buttons on her clothing, revealing a bit of her shoulder and the purple straps of her undergarment.

"I... I'll change in the bathroom!"

I hurriedly picked up the pink swimsuit and covered my flushed face, escaping into the bathroom.

...

My older sister must think that I lack confidence and feel embarrassed to undress in front of her, right?

Leaning against the bathroom door, I felt my breathing become heavy from nervousness.

This is the logical way to change separately, so she won't suspect anything. I carefully turned the lock on the bathroom door, making sure it locked slowly, bit by bit. I was being extra careful because I didn't want my sister to hear the sound of me locking the door. I was worried she might get hurt and misunderstand that I have a barrier against her, even needing to lock the door just to change clothes.

But I really had no choice. What if she really pushed the door open and found out that I am actually a boy, and that I've been lying to her all this time?

She trusts me so much, even being comfortable undressing in front of me. I really feel sorry for deceiving her...!

Silently, I took off the maid outfit and neatly folded my underwear, then put on the pink swimsuit.

It's not the first time I've worn it, so I didn't feel as ashamed this time. Of course, the main reason was that I didn't look at myself in the full-length mirror.

Hmm...

Even though I didn't look in the mirror, I knew I was really flat, not even an A cup. Sigh... Thankfully, there's a bit of lace to cover it up. Although the padding is waterproof, I won't delude myself anymore...!

Next, I tied the cover-up like an apron around my waist, deliberately covering up the slight bulge, and successfully accomplished my mission. I suddenly felt like the design concept of this cover-up was to hide the chest of girls with small breasts when wearing a swimsuit, but on me, it couldn't achieve both purposes.

I have already put on the swimsuit, and now I am staring at the bathroom door.

Just walk out like this...

Shouldn't be a problem, right?

Feeling uneasy and full of turmoil.
