The Final Test of Being a Girl

(Sun Yao)

"Eh! M-Miss Yin Wei?"

Although she was not wearing her work suit, she was still dressed quite formally in a light trench coat with a gold silk blouse underneath. She looked sharp and dashing, and combined with her usual unsmiling expression, she even resembled a crime movie boss lady.

Being caught red-handed in a lingerie store by someone who knew my true identity made my embarrassment multiply tenfold.

"You know me?"

She leaned in with a blank expression and examined me, only then seeming to realize something.

"Isn't this Ceruno? You changed your hairstyle, so I didn't recognize you at first."

Just changing my hairstyle and hair color had actually made her fail to recognize me. This disguise was really effective.

I grabbed my hair and stammered out an explanation.

"I used my magic to do this... Um... Are you off today?"

"Mm, I'm off. But what about you? You came out alone to buy lingerie?"

"Not exactly alone. My brother is waiting outside."

Yezi was probably bored out of his mind playing on his phone right now.

Miss Yin Wei followed my gaze toward the shop entrance, then asked, "Shouldn't you bring a woman along for this sort of thing?"

"Well, I don't have many friends, let alone female friends I can be honest with about my identity."

I spoke very softly, and Miss Yin Wei sighed along with me.

"Sigh. Then come to me. Helping magical girls solve problems outside of combat is part of my duty as a liaison officer... So, what trouble are you having?"

Miss Yin Wei was too serious, which made it harder for me to ask. Luer, who felt more like an older sister, was definitely easier to get along with.

"Actually, I don't really understand lingerie sizes."

"Is that so? Do you remember your bust and underbust measurements?"

Too embarrassed to say them aloud, I merely nodded.

"It's enough that you know them. Don't worry, I wasn't planning to pry. I'll just teach you how to choose."

Miss Yin Wei casually took a white bra from the shelf, turned over its tag, and explained, "Lingerie sizes are made up of two measurements. Take this 36C, for example. The number in front represents the underbust... I see. This shop uses British sizing, so that's why you were confused."

She looked around the store, then found a reference chart on the wall.

"Ceruno, compare your underbust measurement to this chart."

My eyes skimmed over the table, and I quietly said, "...It looks like I should choose a 30... Is that the number at the front of the size?"

"Only 30? You're much slimmer than I imagined."

After glancing at my chest, Miss Yin Wei continued explaining with the tag in hand.

"Next is the letter after it. That represents your cup size. Subtract your underbust from your bust measurement from the physical examination. The difference is the reference number for your cup size."

I calculated it in my head first, then checked the chart.

"19.6... E... Uh, so I'm a 30E?"

"What is with that ridiculous size? You really are something else."

Even without Miss Yin Wei saying so, I thought it was pretty incredible myself.

I often saw people online talking about 36D, and that apparently counted as an outstanding size.

And now, I was even more impressive in every regard...

No wonder Yezi had looked so awkward before, like he didn't know where to put his eyes.

But why had I ended up like this?

I came up with a possible explanation.

"Miss Yin Wei, maybe it's because I used to be fat... So after transforming, all the fat gathered in my chest."

The more I thought about it, the more reasonable it seemed. Otherwise, where had all that fat from before my transformation gone?

"Sigh, whatever the reason, just choose according to that size."

However, Miss Yin Wei was clearly a little disappointed. As for why she was disappointed...

My gaze fell on the barely noticeable rise at her chest.

"Miss Yin Wei, there's no need to care about something so trivial. I think you're cool and dependable, and clothes like suits, which lean toward a more masculine style, aren't suitable for girls with overly large chests anyway."

Her outfit today also had that androgynous style.

Combined with her tall figure, long legs, and slim waist, she was very attractive even without caring about bust size.

Come to think of it, Miss Yin Wei and Miluno gave off very similar impressions. Both were calm, tall, and dependable. Could Miluno be Miss Yin Wei's transformed form? Was being a liaison officer merely a disguise?

...No, that probably couldn't be true, right?

"You're still too young to be comforting me, kid."

She tapped my forehead, and I covered it as I reflexively apologized.

"Sorry."

"Why are you apologizing again? Pick out a few sets of lingerie first. I'll teach you how to put on a bra."

"...Eh? You'll teach me yourself?"

That meant I would have to take off my clothes in front of Miss Yin Wei...

"Mm. If that makes you uncomfortable, I can teach you from outside the curtain."

The structure of a bra looked easy enough to understand, and I didn't think putting one on would be that difficult. But since Miss Yin Wei said so, there had to be techniques I didn't know. At times like this, I should humbly accept guidance.

"Then I'll leave it to you."

"So you don't need me to wait outside?"

"Mm, there's no need. If it's Miss Yin Wei... I don't mind."

Actually, I did mind. Taking off my clothes in front of a woman was still rather difficult for me.

"If you really didn't mind, you wouldn't be so shy."

"I'm going to pick out some lingerie!"

After wandering around the store for another lap, I finally settled on a plain white bra. I really wanted to pick some of the more "sexy" styles, but I didn't want Miss Yin Wei to think I was a pervert.

After that, I entered the fitting room.

Just as we had agreed, Miss Yin Wei followed me inside.

Since bras were intimate garments, the store only allowed customers to try on the upper half, and they even provided special samples for fitting. Naturally, packaged matching lingerie sets could not be tried on; once opened, they had to be purchased.

I pulled the fitting room curtain closed, took off my upper clothes in front of Miss Yin Wei, and dismissed the underwear that came with my battle outfit.

"Mm, that 30E cup really wasn't an exaggeration... Don't wear such loose tops normally. They don't suit you. Not only do they hide your bust, they also make you look fatter."

In response to Miss Yin Wei's advice, I supported the fat weighed down by gravity at my chest with my forearms and nodded.

Although I was embarrassed, I wasn't as embarrassed as I had imagined I would be.

Miss Yin Wei's calm, unflappable personality affected me to a certain extent, cooling my thoughts down.

"...How do I put it on?"

"First, slip the straps over both shoulders, then lean your body slightly forward and—"

An alarm suddenly blared.

[Warning. A phase wormhole has been detected in Area C4. It is expected to fully expand in... three minutes. Only three minutes remain! Residents in the area, please evacuate quickly and orderly. I repeat...]

Miss Yin Wei sighed.

"—Looks like my vacation is ending early."
