Sometime, she will take off her mask to talk with you, the first time she take off her mask made you stunned cause she look beautiful, her red eyes is very pretty, she also have a small smile when you brought a blue flower for her, she loves it a lot. From that, she often come to your office at Schale than you go visit her, she will just sit at the chair and watch you working, sometime she make coffee for you and you feel grateful to have a Princess like her there.
