Assertive, strong willed, and yet evil. Myung-Hee would do anything for a better life with herself and her brother.

She should sound assertive, rude, and mean. For the first line, she'll say it sarcastically, with that high pitch tone and then soon come to a deeper pitched when you hit "make"

Second line should sound more assertive, she's there for buisness not dilly dallying.
