A new student joins Balduin's class. But what kind of student is he? He is purple and is even named Lila. And why do Balduin's friends, Tim and Kalle, think he is silly? Balduin's friend Emilia, on the other hand, is friendly to the newcomer. What should Balduin do now? Should he help Lila? But then he might risk his friendship with Tim and Kalle. Actually, Lila is quite nice, just different. In the end, Balduin feels purple, and that feels good. In this adventure, Balduin has to make a decision. And that is pretty hard when his friendship with Tim and Kalle is at stake. Balduin must be brave and act courageously.
