Regarding the fact that my best friend is a magical girl

(Sun Yao)

A person came in.

Lingerie stores truly live up to their reputation as a no-go zone for men and a sanctuary for women; even the air seems to smell sweeter there… Oh, I guess I did spray on a light fruity perfume.

The female shop assistants and other female customers didn't give me any strange or disdainful looks, after all, I was now just like them, and naturally belonged here.

Although I understand this, I still feel a sense of guilt.

She tried to appear calm, but her face was flushed uncontrollably. She had only been a girl for two days and hadn't yet adapted to her new identity. Even those awful and vulgar thoughts were involuntarily popping up.

No! I need to control myself!

Now is the time for young girls to cultivate themselves, and to calmly and confidently choose their favorite lingerie is the proper behavior of a lady.

Even if it's just for show, you have to convey that feeling.

This store has a pretty girly style. They don't sell those so-called "winning lingerie" items. The designs are cute, using tulle instead of the usual openwork lace, which suits my current look quite well.

I know I'm cute.

Yezi also thinks I'm cute.

So I want to become even cuter.

I walked around the store, looking at the dazzling array of lingerie, and soon realized something.

Because I had a physical examination at the association, I know my bust, waist, and hip measurements, but I can't understand the size label on the bra and I'm not sure which one I should buy.

Generally speaking, you should ask the store clerk at this point.

But social anxiety is an occupational hazard for otaku, so I chose to ask Baidu.

"Is there anything I can help you with, young lady?"

I had just taken out my phone when a kind woman struck up a conversation with me. I nervously turned around, only to find...

Chapter Twenty: The Final Test of Being a Young Girl

(Sun Yao)

"Eh! Miss Yin, Miss Yin Wei?"

Although she wasn't wearing a suit for work, she was still dressed in a very formal thin trench coat with a gold silk shirt underneath. She looked so dashing and neat, and with her usual serious demeanor, she even resembled a female gangster in a gangster movie.

Being caught red-handed in a lingerie store by someone who knew my background made me feel doubly embarrassed.

"You know me?"

She leaned closer to me with a blank expression, scrutinizing me before she seemed to suddenly realize what was going on.

"Isn't this Seruno? She's got a new hairstyle, I didn't recognize her at first."

Just by changing my hairstyle and hair color, they really didn't recognize me. This disguise is really effective.

I grabbed my hair and stammered an explanation.

"This was achieved using my magic... Um... Are you taking a break today?"

"Hmm, taking a break. But you, coming out to buy underwear all by yourself?"

"I'm not alone; my brother is waiting outside."

Ye Zi is probably bored and playing on her phone right now.

Miss Yin Wei followed my gaze to the outside of the store and asked, "Shouldn't you have a woman accompany you for something like this?"

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

I spoke very softly, and Miss Yin Wei sighed as well.

"Sigh, then come to me. Helping magical girls solve problems outside of battle is my duty as a liaison... So, are you having some kind of trouble?"

Miss Yin Wei is too serious; I find it difficult to speak to her. As expected, Miss Lu'er, as my older sister, is much easier to get along with.

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

"Really? Do you remember your bust and waist measurements?"

I was too embarrassed to speak, so I just nodded.

"Just keep it to yourself. Don't worry, I don't intend to find out the details. I'm just teaching you how to choose."

Ms. Yin Wei casually picked up a white bra from the shelf, then flipped out the tag and explained to me: "The size of a bra is actually made up of two numbers. For example, this one I have is a 36C. The first number represents the underbust measurement... I see. This store's sizes are in feet, which is why you are confused."

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

“Serno, take your underbust measurement and compare it to this chart.”

My eyes swept over the form, and I whispered, "...I think I should select 30 feet...is that the number before the size?"

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

After glancing at my chest, Ms. Yin Wei continued explaining while holding the sign in her hand.

"Next, let's talk about the letter that comes next. This represents your bra size. You subtract your upper and lower bust measurements from the measurements you get during your physical exam, and the difference is the reference number for your bra size."

First, do mental arithmetic, then compare it with the table.

"19.6...e...uh, so I'm 30e?"

"What's with this exaggerated size? You're really something else."

Even if Ms. Yin Wei didn't say it, I myself think it's amazing.

I often see the term "36D" online, which seems to indicate an excellent level of breast size.

Now I am better in every aspect...

No wonder Ye Zi looked so awkward before, not knowing where to look.

But why did it turn out this way?

I came up with a possible reason for this situation.

“Miss Yin Wei, it’s probably because I was originally quite fat… so after the transformation, the fat accumulated in my chest area.”

Thinking about it this way, it seems quite reasonable. Otherwise, where did all that fat I had before I transformed go?

"Sigh, whatever the reason, just choose according to this standard."

However, Ms. Yin Wei was clearly somewhat disappointed, as for the reason for her disappointment...

My gaze fell on the barely perceptible rise and fall of her chest.

“Miss Yin Wei, there’s no need to worry about such a small thing. I think you are very handsome and reliable. Besides, a suit is a rather unisex garment and it’s not suitable for girls with large breasts to wear.”

Her outfit today also features this androgynous style.

In addition, she is tall with long legs and a slim waist, so she is quite attractive even if she doesn't care about her bust size.

So, Ms. Yin Wei and Miluno give off a very similar impression. Both are calm, tall, and reliable people. Could it be that Miluno is Ms. Yin Wei's transformed form? And the identity of the liaison officer is just a disguise?

...No, that shouldn't be happening, right?

"It's too early for you to comfort me, kid."

She tapped my forehead, and I instinctively apologized while covering my head.

"Feel sorry."

"Why are you apologizing again? Pick out a few sets of underwear first, and I'll teach you how to wear a bra."

"...Eh? You're going to teach me yourself!"

In other words, you have to take off your clothes in front of Miss Yin Wei...

"Well, if you mind, I can teach you through the curtain."

The structure of a bra is easy to understand at a glance, and I don't think it would be difficult to put on. However, since Ms. Yin Wei said so, there must be some techniques that I don't know about. In this kind of situation, we should humbly accept them.

"Then please."

"Does that mean I don't need to wait outside?"

"No, no need. As for Miss Yin Wei... I don't mind."

Actually, I would mind; it's a bit much for me to take my clothes off in front of women.

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

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

After wandering around the store for a while, I finally settled on a simple white bra. Although I really wanted to get the more "sexy" styles, I didn't want Ms. Yin Wei to think I was a lecherous person.

After that, I went into the locker room.

Just as agreed, Ms. Yin Wei also came in.

After all, bras are intimate apparel, and you can only try on the upper body in the store. There are also special samples for trying on. Naturally, you can't try on the complete set of underwear in the package. Once you open it, you have to buy it.

I drew the changing room curtains and, in front of Miss Yin Wei, removed my upper body clothing and the underwear that came with my battle suit.

"Yeah, your 30E-cup is no exaggeration... Don't wear these loose tops normally, they don't suit you, they not only hide your bust size, but also make you look fat."

I nodded in response to Ms. Yin Wei's suggestion, supporting the fat on my chest with my forearm.

Although I was shy, I wasn't as shy as I had imagined.

Ms. Yin Wei's calm and composed personality also influenced me to some extent, cooling down my mind.

"...What should I wear?"

"First, put on the shoulder straps on both sides, then lean forward slightly to let—"

The alarm suddenly went off.

[Alert! A phase wormhole has been detected in area C4. It is expected to fully deploy in three minutes. Only three minutes! Residents in the area, please evacuate as quickly and orderly as possible. I repeat...]

Miss Yin Wei sighed.

"—It seems my vacation has ended early."
