Tal is a 17-year-old high school student living in Jerusalem. Following a deadly suicide bombing at a nearby cafe, she struggles to maintain her optimism and dreams of becoming a filmmaker. Driven by a desperate need for peace and mutual understanding, she writes a letter and places it in a bottle, hoping to connect with a Palestinian peer across the border.

Naïm is a 20-year-old Palestinian man living in the Gaza Strip. Initially responding to Tal under the pseudonym "Gazaman," he writes back out of frustration with his highly restricted life and anger over the political situation. Beneath his sarcastic exterior, he possesses a sharp intellect, a deep weariness of the ongoing violence, and a desire for personal freedom.

Eytan is Tal's 18-year-old older brother, currently serving his mandatory military duty in the Israeli army. Stationed in Gaza, he acts as a literal and physical bridge between the two territories. He is highly protective of his younger sister but ultimately supports her unconventional attempts at outreach by leaving her bottle on the beach.

Efrat is Tal's best friend in Jerusalem. She shares the typical concerns and fears of an Israeli teenager living under the constant threat of unpredictable violence. She is a loyal companion, though she remains largely unaware of Tal's secret cross-border communication.

Ori is Tal's thoughtful and dedicated boyfriend. He offers comfort and stability during Tal's moments of anxiety, sitting with her when the stress of their environment becomes overwhelming. He cares deeply for her but does not know the full extent of her internal crisis.

Tal's father works as a tour guide and serves as the family's resident historian. He possesses a deep, long-term perspective on the ancient history of Jerusalem, preferring to view the city as a historical marvel rather than a war zone. He encourages Tal to look beyond immediate violence and remember the city's enduring legacy.

Tal's mother is a sensible, routine-driven woman who copes with the unpredictable violence in Jerusalem through immediate, practical action. She manages her severe anxiety for her children, particularly her son serving in the military, by seeking out factual information the moment a crisis occurs.

Paolo works for an Anglo-Italian non-governmental organization providing psychological aid in Gaza. As an outsider with a foreign passport, he enjoys basic freedoms that completely elude the local population. He treats local residents as distinct individuals rather than anonymous statistics.

Willy is a colleague of Paolo at the Anglo-Italian NGO. He helps provide Naïm with a rare, safe space to use an internet connection, encouraging the young man to express his emotions without fear of government surveillance or social judgment.

Naïm's father is a hardworking nurse who treats victims of the ongoing regional violence in a local hospital. He once held incredibly strong hopes for peace following the Oslo Accords, even teaching his son Hebrew in anticipation of open borders, but now suffers from profound exhaustion.

Naïm's mother is an elementary school teacher with a perpetually tired face. In a culture where large families are highly common, she channels her maternal energy into her many students to compensate for having only one biological child.

Shira is Ori's sister. Her dramatic, expressive personality provides Tal with a humorous distraction from the daily news and helps her put minor, everyday teenage problems into a much lighter perspective.
