The previous owner turned into a stalker and followed the girl all the time. Things would have turned out differently if the girl actually had a boyfriend or something. But to her misfortune, she was alone and single. Her parents lived in the countryside, not even sending any mail. They were completely isolated.
The only contact the girl would ever have with her parents was when she would go once a year for a few days during the Christmas holidays.
After the guy was clear on Hope's schedule and her entire life, per se, he decided to make her move. He approached her when she was in her most desperate situation.
Actually, the previous owner knew that the girl would go to the bar with her friends once a month to drink. The previous owner had to stalk the girl for half a year for this.
