In the role of the mother of Stéphane's children, the director called on director Delphine Gleize. This is her first acting experience. Éric Lartigau explains this choice: "I like this character with whom Stéphane has kept an accomplice relationship despite their divorce. I wanted someone generous, with a beautiful look once again without judgment. Delphine exudes something very soft, loving and sensual. She also has a lot of character and she is a good friend of mine".
