I found the story very bittersweet but, more on the bitter side. I don't think the evil sister deserved a happy ending and I’m glad she didn’t get one which was her death....
I think it realistic for the older sister (the good one) to still be suffering but I don’t like the fact that she adding the fake mole to her face at the end... it too much like her evil sister and I don’t like that....
To end this on a good note the story was nice and different from others and I liked it and it was be nice if this had a follow up to this ~
