Bruno, 13, is in a panic: he has discovered that Flavia reciprocates his love, but he has no idea how to start a relationship. He needs someone to teach him, and Luca, whom he despises, is the only man who has made his stonehearted mother, Claudia, fall in love. Bruno will be forced to put aside any contrast and follow the advice of his worst enemy. Bruno doesn’t know that Luca and his mother live a fragile, undermined, and not at all exemplary relationship.
