Leo lives in a tall apartment building in the middle of a busy city. The city is noisy, with cars honking and people rushing everywhere. However, Leo has a secret place where he can find peace. It is not a park or a library; it is the rooftop of his building.

Two years ago, the rooftop was just empty gray concrete. Leo decided to change it. He started with a few small pots of mint and basil. Slowly, he added more plants. He planted bright red tomatoes, yellow sunflowers, and even a small lemon tree. He carried heavy bags of soil up the stairs and watered the plants every evening after school.

Now, the rooftop has turned into a beautiful green garden. Bees and butterflies visit the flowers, and birds sing in the lemon tree. It feels like a different world. Leo likes to sit there and do his homework or just watch the sunset. The air smells fresh and sweet, unlike the dusty air down on the street.

One afternoon, his neighbor, Mrs. Green, came up to hang her laundry. She was surprised to see the garden. "Oh my goodness!" she exclaimed. "I didn't know we had such a paradise up here." Leo smiled and gave her some fresh mint for her tea.

Since then, other neighbors have started to visit. They bring chairs and sit among the flowers to talk and relax. Leo is happy because his secret garden is not just for him anymore; it has become a place of joy for everyone in the building. He learned that nature can bring people together, even in a crowded city.
