Living in the castle, she experiences traumatic dreams and finds a mysterious cat that visits her at midnight from time to time. As time progresses, Mila discovers a deep, dark secret hidden far beneath about her past, or rather, the present. Will she forgive those who betrayed her? Or will she be blinded by revenge?
