Simón is a shy boy who shares a flat in Seville with Rayco and Juan. He works in a small neighborhood supermarket and is terrified of making a fool of himself. Insecure, his role is that of the typical village virgin pringao. He has the support of his friends, who advise him how he should face his life, get away from his fears and act naturally. When he tries, forced by circumstances and pressure, his actions turn out to be robotic. He is attracted to Maria, although he can't find a way to get close to her. His colleague Rayco will be in charge of leading him on the right path, although from another dimension.
