“The refined daughter of a Duke strikes back against the bizarre charges put on her...with the help of her Dear Brother, of course!”

Catia has always hid her face under a mask during her days at the academy. Now, right in the middle of the graduation party, her fiancé the First Prince calls off their engagement, accusing her of being as mean-hearted as her ugly appearance. But he should've thought twice, because after all, who ever said beneath the mask was an ugly face?
