The story is completely autobiographical and came to life as a way for Anna Alfieri to cope with her life circumstances.
Anna was initially writing the film as she was going through her real life events, trying to shoot at the same time.
However, she had to put production on hold for 2 months, after her first cinematographer called it quits out of lack of belief in the film. Finding the perfect director of photography took Anna 2 months, more than a 100 applicants and about a dozen test shoots with her co-lead actress (Agathe Ferre') who had, by that time, been confirmed for the part.
All the scenes were loosely improvised around a 12 pages skeleton that kept being revised over the shooting period. The overall amount of improvised footage was around 40 hours, with almost every scene shot in one take, with the camera constantly following the action.
All the flashbacks in the film were shot in chronological order to allow the actresses to reconstruct a love story as organically as possible.
Anna decided to keep her original name and surname to preserve the story's rawness and authenticity.
