Don't ask Mina Akiyama why she's smiling so happily, because she knows exactly what makes Miss Ayukawa look the way she is today.

When Mina Akiyama noticed that Miss Ayukawa seemed to have something abnormal today, she immediately began to calculate the time silently in her heart, and naturally knew that it seemed that about a month had passed since Miss Ayukawa's "last" visit? So this is why Mina Akiyama is now looking at Miss Ayukawa's side face and always smiling so meaningfully...... Presumably, today is the day when Miss Bukawa's "that" came to her.

What, you ask, Mina Akiyama, how did she know about such a thing?

- Well, depending on Miss Ayukawa's personality, of course, it is impossible to reveal to any of the guests what her menstrual cycle is.

But this kind of thing doesn't need to be told by others to know, after all, Mina Akiyama and Miss Bukawa are also women, after all, such things have been experienced many, many times, so can't she just guess it by looking at Miss Bukawa's reaction?

And after all, they've been together for such a long time, and Akiyama Mina can also carefully observe which days of the month Miss Ayukawa will be different.

In this way, of course, you can know what the menstrual cycle is.

#↑ Having said so much, it's nothing more than the word "idiot"#

Presumably, she should be the only one who is paying close attention to Miss Ayukawa's monthly affairs in this shop, right? So, Akiyama Mina really likes to observe what Miss Ayukawa's reaction looks like in these days of the month...... Although the difference between Miss Ayukawa and usual at this time is really only so many subtle details, but it is such a "small" difference that makes Akiyama Mina feel very high every time.

After all, in these days, Miss Ayukawa will always slow for a second to react, and it feels a little cute, doesn't it?

#步川小姐: Excuse-me?

Although she thinks like this, for Miss Bukawa, who is suffering from physical pain over there. It seems that there is indeed a little bit of unkindness, but Akiyama Mina just thinks it is cute! Who called Miss Ayukawa to have the same gentle attitude towards her as she did to everyone else?

Even if it's just a little bit, Mina Akiyama wants to discover as many unusual details as possible that Miss Ayukawa hides beneath her plain exterior.

After all, it makes her feel a little better than the rest of herself, doesn't it?

It's because she always thinks about strange things in her head, so now looking at Miss Ayukawa sitting so quietly on the sofa and gently sipping hot tea, Mina Akiyama will be completely uncontrollable and directly make up a lot of things in her brain - after all, knowing that Miss Ayukawa is now suffering from physical pain, Mina Akiyama can even guess that Miss Ayukawa must be thinking about "why do women have such things" and "can't you not come?" Wouldn't the world be destroyed if there wasn't such a thing?"

All right. Mina Akiyama admits that she seems to have made up Miss Ayukawa's brain a little strangely, but she just can't help but think about it this way.

#↑ But Miss Ayukawa is really full of these things#

Of course, Akiyama Mina's side is just making up for it in her own head, after all, it's good to entertain yourself with this kind of thing, isn't it? In terms of appearance, Akiyama Mina naturally kept her usual attitude as much as possible in order not to let Miss Ayukawa find something out of her reaction.

Just as Miss Synkawa pretended to say, "I'm no different today than usual," Mina Akiyama pretended to say, "I didn't find anything today."

――Sometimes I really don't understand you humans.

Anyway, Mina Akiyama won't let Miss Ayukawa find out, after all, if Miss Ayukawa hides her reaction deeper because of this, wouldn't it be completely fun? So Akiyama Mina is still very scruples...... Well, although it does seem to be ambiguous to say this, Mina Akiyama is still calm about her feelings, and she decisively hopes that she can know when Miss Ayukawa's menstrual period is.

It's really not a pervert or anything like that, Mina Akiyama just wants to know more and more about Miss Ayukawa.

It's normal for people!

This strange topic about menstrual periods will not continue here for the time being, and Mina Akiyama is very happy to drink the wine that Miss Ayukawa has added to herself, and then suddenly her eyes are slightly shining with starlight as if she remembered something very interesting.

I saw that the corners of Akiyama Mina's mouth were very obviously upward.

He calmly put down the wine glass in his hand. Mina Akiyama turned her head to look at Miss Ayukawa and suddenly said, "Ah." By the way, Tsukikawa, do you know the school 'Sakurai No. 2 High School'?"

While saying these words slowly, Akiyama Mina was still pretending to be casual, but in fact, she was carefully paying attention to Miss Bukawa's reaction-sure enough, she directly noticed that Miss Bukawa suddenly subconsciously pinched her fingers.

After noticing this, Mina Akiyama gently withdrew her gaze without a trace, but the smile on her face deepened a little.

Ah. Miss Bukawa finally showed a little flaw, didn't she?

I think it's probably because I'm in the middle of my menstrual period now, and most of my attention is attracted by the physical pain on my body, but anyway, Miss Ayukawa's vigilance at this time is definitely a lot weaker than usual...... Otherwise, how could it be like Zheng Yanzi now, directly revealing such an obvious flaw on her fingers? In short, to get back to the point, since Miss Buchuan almost leaked the name of her school directly when she was not paying attention. Akiyama Mina's side has naturally never forgotten it, and has always put this in her heart. (To be continued.) )
