All Amy needed to do was get away from her pursuers. The last thing she thought she'd encounter was being kidnapped, drugged and offered to some smelly fat old man.

But no, he wasn't any of that. Zach was simply a god. And he was drugged, just like her. It could be the drugs or she just genuinely found him irresistible.
