I was thinking, maybe, she is some rich little lover who opened a small flower shop to cover up. After all, I didn't see any men around her all day long, but she was so beautiful; or maybe she was the kind of resentful woman who was hurt and heartbroken by love, because her tone was emotionless and she seemed to take everything very lightly... And the more explanation is - she is not a human at all, she is a goblin!
