And the situation gets complicated after he meets, casually, on a street in the Liberdade neighborhood in São Paulo, the young Yoko. Cheerful and sensual, with her observations, she makes a strong impression on him. And later both realize the strong communication that exists between them. Lauro ends up falling in love with her, maintaining a parallel romance. His bachelor party turns into an orgy with the presence of transvestites. After several existential crises, when he almost puts his romance with Leonora to ruin, he marries.
