Aunt (Eva's older sister)
Helena is Eva's older sister and the complete opposite — while Eva builds a home, Helena explores the world. She's traveled to every continent and always comes back with gifts, spices, and stories she never finishes — on purpose, to spark the imagination. She's never married, says the whole world is her family. The kids adore her because she treats them like adults and never says 'you're not allowed'.

Eva and Dundo had a rare day off without the kids. Otto and Maria eagerly stepped in, babysitting the little ones while the couple decided to revisit the place they first met. As they approached the old wooden bridge over the stream, Eva reminisced about that evening, while Dundo had a special gift hidden in his pocket.

In the basement of an old building in the square, there was a library that wasn't on any map. It had no sign, no opening hours, and the doors opened only for some. Hana stumbled upon it by chance, escaping the rain. She descended the wet steps, pushed the heavy wooden door, and entered a room full of books from floor to ceiling. It smelled of old paper, wood, and something sweet—like honey mixed with dust. At the table sat Helena, Eva's sister, with a smile that promised adventures. Loli, the family cat, curled up on a shelf, watched Hana with her green eyes. "Go ahead, but don't choose," Helena said, without lifting her gaze from the book in her hands. "What?" Hana was puzzled. "In this library, you don't choose books. Books choose you."

When Hana was cleaning the attic after her grandmother's death, she found a box full of letters. Hundreds of them, neatly arranged, each in its own envelope — but none of the envelopes were sealed. And none had an address. "Dad, did Grandma Maria write letters she never sent?" she asked Dundo, who was standing on the ladder. Dundo climbed up into the attic, took a letter, and read it. His hands trembled. He took another. A third. Each letter was addressed to the same person — but it wasn't a name Hana had ever heard. "Who is Helena?" Hana asked. Dundo was silent for a long time. Then he sat on the dusty attic floor and said, "Sit down, Hana. Your grandmother Maria kept a secret for fifty years. And I think this box is her way of finally telling you."
