Giuseppe's obsession isn't a character flaw, it's the only honest response to love that matters. He watches Pechka the way he watches everything else, total and consuming, and the movie knows that kind of focus is the only thing that breaks through sadness. A man and a mouse solving a girl's pain one small trick at a time, because sometimes love means paying attention to what nobody else bothers to see.
Giuseppe earns his nickname from the locals for a reason: once something captures his attention, nothing else exists. When he sees Pechka selling balloons, he falls for her on the spot, and she becomes his new fixation. But Pechka carries a quiet sadness. With his mouse partner Cielo, Giuseppe draws on the many tricks and skills he has picked up from past obsessions to work behind the scenes, easing the worries that weigh on her heart. The result is a music-driven animated film about devotion.
