Wild Mom (2007)

Ayu Kawano (Aya Ueto) is a tomboy-ish girl of the sea. She isn't well-educated, but she's upbeat and has an honest heart. Married to her is a once-divorced stylist, Tetsu Kawano (Yo Oizumi ). One day, Tetsu's five-year-old son arrives at their shop, and their happy newlywed life turns into chaos.
