I do want to point out that if she had just woken up and not had memories from another life, her mental age would still just be 6 (sure, the body and brain would quickly try to get the mentality up to date, but that would still take months if not several years)
In short the man was treating her as if an adult when he should be thinking about her like a child.
And to be fair. Her behavior could have easily be misunderstood as the behavior of a child, not getting overly flustered, not understanding sexual ques and so on.
Either way, even if he is spoiled, his actions were kind of excessively creepy. ^_^,
