Once upon a time in a mountain called Anboto, a creature with a human body an a goat appearance was walking, his name was Akerbeltz. Suddenly he saw a female silhouette inside a cave. He approached slowly, and he could appreciate a beautiful woman. Her long brown hair matched perfectly with her honey-colored eyes. Akerbeltz wanted to talk to her but when he saw that she was looking at him he embarrassed and he went to get help from his friends the Galtzagorriz.

-Galtzagorriz!

The galtzagorris were playing in the trees when they heard the scream of Akerbeltz and they turned to see what was happening.

-What's up, Akerbeltz? -asked a galtzagorri.

-I have seen a very beautiful woman and I have fallen in love with her.

-And what's the problem with that?

-I don’t know her name and I don’t dare to speak to her -said Akerbeltz sadly.

-We will help you to conquer it, I think you mean Mari -said the Galtzagorri.

Akerbeltz smiled at them and thanked them. All the Galtzagorriz got together and started talking among themselves. Akerbeltz was confused. Suddenly the Galtzagorriz shouted happily:

-We have a plan! We have a plan!

-You can tell me? -asked Akerbeltz.

-Obvious, listen.

The Galtzagorriz began telling their plan, which was about writing a love letter to Mari, since he did not dare to speak to her face.

-It’s a good idea -said Akerbeltz.

He started writing the letter:

Dear Mari...

When he finished writing the letter he handed it to the Galtzagorris to be left in Mari's cave. Meanwhile, Mari was with her best friend Eguzki, talking about things.

Mari went to the bathroom, and then the Galtzagorris sneaked up to the cave and left the letter. Unintentionally, a Galtzagorri stumbled and made a lot of noise. When Eguzki heard the noise, she realized there was someone in the cave.

She approached to see what was happening, but when she arrived at the door there was nobody. There was only one envelope.

Eguzki opened it slowly and pulled out a letter. The letter was for Mari but Eguzki was curious and started reading it.

“Dear Mari,

Since I saw you my heart only beats for you. You are the girl of my eyes. You are beautiful as a rose. Would you like to stay with me one day? If so, I'll be tomorrow at five o'clock in the river of the swans.”

At that moment Mari leaves the bathroom and goes to where her friend Eguzki is.

- What happened? -asked Mari, who had heard the noise.

- Nothing, nothing. - Eguzki replied hiding the letter quickly.

And she went to the sofa. Mari did not suspect anything, and she was behind her. They started watching a movie. While, the galtzagorriz went to where Akerbeltz was, to celebrate that the plan had gone well.

The next day Akerbeltz woke up happily, because he was going to meet his beloved.

Meanwhile, Eguzki was in her house jealous of Mari. And suddenly an idea occurred to her. She was going to write a letter pretending to be Akerbeltz and telling her that he did not want her, to get angry with him.

Eguzki calls Mari and they stay in the morning at Mari's house, to talk like every day. Mari was in her living room waiting for Eguzki. While Eguzki was keeping the letter he had written in the mailbox.

- Mari, you have a letter in the mailbox. said Eguzki.

-I'm going now

Mari takes the letter out of the mailbox and started reading it. And she stays in shook when she saw what it puts.

Eguzki pretends to see surprised and asks her: -What's wrong?

Mari shows her the letter and Eguzki reads it as if she doesn´ t know nothing.
