The story seems to be good but it would have been better if she overcame all the odds and finally become a powerful person without having her birthmark removed. Again, It just proves Korea's beauty standards.
@Tsuru1237 I mean, the world she lived in shunned her BECAUSE of her red eyes and birthmark. I don't think it has anything to do with her beauty. It has to do more with the fact she knows what'll happen already and is taking steps to prevent that. From the promo, I'm assuming she wears the mask even though anyways.
I'd be more interested if her birthmark wasn't removed. It's not even a flaw, Korea, stop having such unrealistic beauty standards! Now she's just a vanilla pretty lady out for revenge and justice, like one hundred others like her.
