Gabriella is the ex-wife of Claudio, the head waiter at the Casetta dell'Orso restaurant in Rome. Her profession is that of a lawyer, and she works in the same legal office as Olga, the owner of the restaurant. The two women are described not just as colleagues but as best friends, sharing a deep and trusting bond.

In terms of her personality and motivations, Gabriella is portrayed as a figure of significance and discretion. She is the sole confidante of Olga, being the only person to whom Olga reveals the secret that the young apprentice Nicoletta is actually her daughter. This position indicates that Gabriella is someone who can be trusted with highly personal and potentially complicated family matters, showing her to be a loyal and reliable friend.

Her role in the story is deeply intertwined with the emotional life of Claudio. Although they are divorced, Claudio remains deeply attached to her and is often described as still being in love with his ex-wife. As a symbol of this lingering affection, he continues to wear his wedding ring, in part to dissuade the advances of other women but primarily as a testament to his feelings for Gabriella. Even though she does not work at the restaurant, her presence is a constant emotional touchstone for one of its key staff members.

The narrative expands on her character beyond the confines of her past marriage. In the sequel manga Gente, Gabriella is given more background and plays a more active role. In one instance, she introduces a woman who is experiencing a run of bad luck to the warm and magical atmosphere of the Casetta dell'Orso, demonstrating her kind and thoughtful nature. Her abilities, therefore, lie not only in her professional legal expertise but also in her capacity for forming deep friendships and her perceptive understanding of others, using the welcoming environment of the restaurant to offer solace to a friend in need.
