There is a legendary tea that she only makes once a year called the Miracle Diamond and that it couldn't be bought with money but she herself has to decides who gets it. The flavour of the tea is like a miraculous scent beckoning from the heaven above.

She is a kind and joyful women. She appeared to have hearing problems at first when the robbers told her to hand them the Miracle Diamond and later when she actually went to get the tea, she pressed the emergency alarm button and called for the police, proven to be quite witty.
