If I were the past me, even if I heard something offensive, I would have let it go with a smile.
I thought it was good to live smoothly without any trouble.
But not now, that I have woken up from the dead.
That holding back brings fortune is a lie. If I held back, I would only get constipation.
"… That's really disappointing."
I replied, staring right at him.
The man's face, who was triumphant with a 'That's right.' look, hardened at my following words.
"I can't believe a librarian is someone narrow-minded like this. I feel that my Father has given a job that is too demanding to a petty person that has only stubbornness in his mind."
"W-What do you mean, narrow-minded? Your words are harsh."
I quickly snapped at the man, who started stuttering as if my counterattack was unexpected.
"How can I not say that you are narrow-minded when it seems like you are boasting about the library not carrying books in a wide range of areas?"
"It has a lot of excellent books, so is there any reason for it to carry third-rate novels that are of no help at all?"
"Is third-rate an evaluation you made yourself after reading them?"
"It's obvious even if you don't read them!"
"I guess you don't think your attitude of not checking the contents of a book properly, belittling someone's creation, and judging it as being third-rate isn't narrow-minded at all. Your attitude of not admitting your own narrow-mindedness until the end is also very narrow-minded."
I continued to use the word narrow-minded, provoking the man's self-respect, and reached for the library ledger lying on his desk before he found any words to refute.
"It's very disappointing that you offered yourself to guide me through the library when you have been managing it so poorly."
Having worked part-time at a library during the holidays, I secretly clicked my tongue while looking at the classification system here.
Since books are valuable and the quantity is considerably smaller compared to modern times, the system for managing books also seemed not as sophisticated.
"What kind of book are you looking for? If it's not a third-class publication, I'll find it right away."
He still couldn't admit to his mistakes and was stubborn.
Isn't there anyone knowledgeable in the Seymour household? It really makes people feel sorry.
"A book with formulas about 3-class magic. Can you find it without wandering a single step?"
He hesitated, not knowing I would request such a specific book.
Judging from the library classification system, it could take you right to the place where the magical formulas are; but finding a 3-class book without wandering was unreasonable.
There is no book search function here.
"If you let this body take just one step carelessly… You know how I am, right?"
I pretended to cross my neck with my thumb.
***
The librarian kept his head down at my threat, saying he was sorry and that only know he understood the situation.
But I didn't even think about kindly letting this go.
'Maybe I've been too soft on the servants this whole time.'
I can't believe there's someone who can be impolite to a princess like this, no matter how powerful of a vassal he may be.
After I memorized his name and face, I went to the upper floor of the library.
'Hmm…'
As the librarian said, this library consisted mainly of magic books.
As I glanced through the bookshelves, I was able to find a book related to mana formulas.
[Introduction to Mana Formulas]
'What is this? It's really thick. I don't even want to open it.'
Why can't I be free from studying even though I was reborn?
'Even though I am an orichalcum spoon, I'm in a situation where I still have to make money.'
Feeling a little depressed, I reluctantly opened the cover of the book.
[This book is dedicated to my dear Danae.]
'Who is Danae?'
I tilted my head and moved on to the next page.
[Me and my colleague, Rikurgos, disagree with the opinion that the flow of mana is extremely irregular and fragmented. Mana, as refined as a river, as light as the wind, and as hard as the ground does not just show a high degree of complexity, but also a completely different level of complexity.
There are countless criteria by which regularity can be understood, all of which exist for countless practical purposes… (…)]
Flicking through the thick book, I clicked my tongue softly.
"… It's very lengthy."
The long preface, spanning 20 pages, explained in detail when and by whom the mana formulas were created, and why they were created.
Formulas began to develop in earnest long before the establishment of the Azutea Empire, dating back to the Tegea Empire.
It was through mana formulas that the archmage, who climbed to the highest level among ancient wizards, arranged the regularity in some shape in order to practically use the mana distributed in nature.
'I finally found it.'
As I looked through the theory book that covered the application of three-circle formulas, I smiled in satisfaction.
Because I got the correct answer to the problem the professor gave us.
'Anyway, I am amazed. Area-of-Effect magic is a geometric progression.'
In this world, it was explained that geometric sequences are mana management skills that expand the range of the magical effect.
You could say it's a wide-area skill that wipes out the beginners in a game.
However, even without that kind of knowledge, finding out the regularity of numbers was a piece of cake for me, an engineering student.
'The more I look at it, the more it stimulates my curiosity as an engineering student.'
The magic for turning mana into a spherical shape is a formula that calculates the circumference of a circle, so I held back a giggle.
'There was a reason for why the wizard looked like an engineering student.'
Magical formulas weren't very different from mathematics, so, as I browsed through the book in an interesting mood, I found something strange and frowned.
There was no basic formula for calculating the sum of geometric sequences.
'Why doesn't the formula appear in this book?'
I scanned through the book with a dubious feeling, in case there was a commentary on the back; and lifted my head to the sound of footsteps getting closer.
Tap tap.
Along with the sound of regular steps, I could see a small figure with shiny silver hair through the gaps between the bookshelves.
It was Enrique Seymour, the youngest of the family.
The sunlight coming in through the large window illuminated Enrique's chubby, rosy cheeks.
Looking at the shiny baby hair on his cheeks and ears, I closed my mouth tightly.
Isn't he totally copper (Cu) and tellurium (Te)? CUTE.
'He's much cuter with his bangs down.'
If Enrique appeared on a family entertainment show, he would probably get thousands of commercials in an instant, with that cold cuteness.
'If you put Enrique in photocards and sell them, they will get sold out in a second. Why? Because I will collect them by type.'
Enrique, who was rolling his big eyes back and forth, chewed on his tiny lips with a very serious face and then suddenly reached out his arms and started hopping like a rabbit.
Perhaps the book he wanted was in a place where he could not reach it.
'Ah. I'm dizzy.'
I was dizzy at the overwhelming cuteness.
To be honest, I was more vulnerable to cute creatures than to handsome men.
In particular dogs, cats, and children were my Achilles' heel.
Seeing that the neighborhood cats gathered around me to get anything to eat whenever I passed through the alley, it seems that perhaps they also noticed that I was a pushover.
'I want to help him.'
It's been a while since I decided to be strong.
'But he's so cute.'
The child's silver hair kept fluttering whenever he jumped, so I touched my forehead.
While I was going through a fierce inner conflict, Enrique barely managed to put his fingers at the end of the book, letting out a groan.
'That's admirable. Enrique. You can do it.'
However, because the book was so tightly stuck, Enrique failed to pull it out this time.
Regrettably, Enrique's silver eyebrows drooped, and his small, round shoulders slumped down.
'That's enough, I lost.'
In the end, I succumbed to Enrique's cuteness.
It was unavoidable. He's so cute, I'm the devil if I don't help him.
"Here."
I approached the child that was mindlessly jumping, pulled out the book and handed it to him in a chic manner, pretending to be indifferent.
'Oh my God. I'm going crazy.'
As I suddenly saw a round head below my field of vision, I had no choice but to gnaw at the tender flesh inside my mouth.
Enrique was frightened by my sudden appearance and took a step back.
Astonishment flashed through the silver eyes of the boy who faced me.
No wonder, he is in the library with Deborah.
I agree that it is like a combination of soybean paste soup and macarons.
"S-Sister?"
"The book you wanted."
Enrique's eyes soon calmed down, coldly.
I felt like I was going to sigh at his alert appearance.
"Were you watching out for me?"
The boy snapped back quite fiercely.
"Yeah. Because you're cute."
I wondered if it was necessary to be frightening even towards a child, so I replied honestly.
Enrique was young and had no presence within the family anyway.
He's a child in a position that doesn't particularly affect my reputation, so maybe I can do whatever I want? That's what I thought.
'Bottom line is that he's cute, so it can't be helped. How can I defeat a cute thing?'
"… What?"
"You're cute. Like a white rabbit."
Enrique blinked his eyes slowly for a moment, with an absurd look on his face.
As if he belatedly understood what I was saying, his round ears gradually turned red.
"D-Don't make fun of me! My Father and my Brothers are tall, so I'll soon be tall too."
I said he was cute because he is cute; but whether I unintentionally hurt his feelings, Enrique got angry.
He only looked cute anyway, as if he were a kitten raising its fur.
"That's right, you will be tall."
I held back a giggle and carefully stroked his round head.
