Let’s meet little Lea. In kindergarten, she has a friend, William. As COVID came along, the kindergarten suddenly closed its doors. Now, the little Lea has no one to play with, but luckily for her, a new baby brother has just joined the family. But until he grows up, she has to entertain herself. Lea has a good heart, is curious, and likes to try new things. If something goes wrong, she tries to fix it. Once a problem is solved, she proudly and loudly announces: Look! I already know.
