Tara, a girl from the school class, is celebrating her birthday. Leon has a huge crush on Tara, but unfortunately she doesn't even notice him. And she hasn't invited him to her birthday either. Max, who is just learning how to rearrange a piece of music with Maestro Barenboim, has an idea! Since Tara is a very fashionable girl, Bak, Emilia and Max decide to give Leon a new outfit so that he can make an impression on Tara. But when it comes down to it, Leon stumbles at school in front of Tara, her friends and the students present. Max realises that it was a mistake to try to bend Leon and comes up with a new plan.
