Beautiful beautiful writing and drawing, but an inconsistent script

Leah, a young woman presenting a download hit on television, tells his life suddenly flashbacks: a doctor father more concerned about his patients as his own daughter, a mother tired of the husband's absence will eventually by leaving them for a vacuum cleaner merchant, a little brother who committed suicide before his birth, an abortion 18 years. Harsh and realistic themes that never sink into pathos. The design is beautiful, artistic. Only drawback, an inconsistency in the script: Lea complains not wanting to spend the holidays with his mother and his stepfather when she was a teenager. Except that when his mother leaves him and his father, Leah is a little girl and her mother died in a car accident nine months later. The author tells us not all exactly the same story.
