—And what is my fight?—Franco asked the question Achilles whispered to him.

—Put the flower they gave that woman on my shelves,—the pretty girl said, looking at Bianca with jealousy.

Franco saw Bianca with the flower in her hair, and Bianca saw how Franco's curious eyes sparkled, knowing what she had hidden in the book on the shelf. Achilles didn't want them to fight in the middle of the main hex, so he ended up helping Franco and convinced Bianca by remembering that this was some kind of class and everyone had to collaborate.

Franco, with a victorious smile, handed the flower to the shelf and took the book from him. But the book was nothing special.

—Bad luck— Achilles said looking at the child's disappointed face —Next time remember to ask what happens if you fail, in this case we already knew, but don't be so impatient

Achilles saw that the two other two scored and went on to say:

—It's your turn Adam, he doesn't use the same bookshelf as Franco.

Adam nodded, went to the third dustless shelf and asked the rules:

Another pretty girl came out, but this one she had short hair and polka dots with stars on her face, she looked at Adam and said:

—Same rules as the other girl. What decision do you make?

Adam was going to continue. But Achilles I know matter; since Adam was a boy from the special class, so he decided to interrupt him from behind saying:

—No, no, no... It would be very easy... very easy, let's try the handsome boy test.

“Coward!” She yelled at the bookshelf before Adam could get close.

—Well, let's try the one with dust— Achilles said, trying not to tempt fate by trying the women—But remember what you were learning and ask everything.

Cautiously, Adam approached the dusty bookcase and asked her the rules.

An old man's head came out from the shelf: unlike the other three, the old man was not very handsome and did not have any decoration on his face, he looked carefully at Adam and with a somewhat tired voice said:

—Tell me who I am, and I'll let you read; answer wrong, and you will clear the other three libraries.

—He preempted the other question—Achilles said wryly; it seemed that he already remembered this old man's response—Think about it, Adam, the shelves always give clues.

— Is there a clue? Adam asked literally.

—I already gave you the clue, try to remember my rules—The old man answered very patiently

Adam thought and thought, but he couldn't come up with an answer, so he asked:

—And for the good guys? Are there bonus tracks?

—...— the old man thought for a while, until he finally said—Look at the outfit

Adam noticed that the old man had no accessories, the other three seemed to have them; if he considered star polka dots as accessories.

—You're his servant!—Lucas answered decisively.

—No— answered the head, disappearing again.

—The correct answer was that she was his father—Achilles said from behind, taking out some rags that he had brought for the occasion—Help Adam clean the four shelves. Tomorrow they can take the day off, meditating because he was the father and not the servant.

The three boys nodded and began cleaning the shelves.

Achilles ended up being the one who cleaned the shelves. While the boys played throwing water at each other; that was the good thing about being young and not understanding the emotional story told by these 4 bookstores.

Only now that he was back as an adult, Achilles was able to understand the story. Unfortunately, the story left a great doubt in his heart, especially as a teacher of so few students; remembering that when he studied there were more in the class.

That story was probably the most valuable secret of these shelves, because when he finished cleaning and the boys went home, Achilles decided to wait a while longer and saw how the last shelf was filled with dust again.
