They Took Away My Countess Title

After eating her desert and falling asleep, Magi woke up lying on a queen sized bed. Next to her was a boy crying while holding her hand. Unexpectedly, the western styled room she was in is filled with people wearing imperial dresses calling her Selene. A suddenly flash hit her. A storm of her past and the current owner of the body's memory flooded. She's no longer the carefree and clumsy Magi but she is Selene. The people around her are familiar because.. not only that these boys are closed with the original owner but these are the main characters in the book she was reading before she had fallen asleep.. No, more like, she has been poisoned. Selene, as she recalls her new name. She's an extra character from the book who has been sacrificed for a dark mage to unlock his power! But she's young right now. Looking at her limbs and her hands. She has the power to change her fate. Or does she?
