It was a typical love story for Kyoko Yamaguchi. The couple met in Europe, fell in love, married and later had a son.

But the happy life she had envisioned soon turned sour. First there were the fights and the yelling, and then the cheating and violence. After nearly 10 years of trying desperately to hold on to her marriage, Yamaguchi, not her real name, left her husband.

But that wasn't enough. Physically and mentally worn out from her husband's abusive and stalkerlike behavior, she finally decided to take her son and move back to Japan without her husband's consent.
