Andrea- Coming from a Fantasy World to Settle in the Interstellar

Ros's gender is female but for her whole life she lived as a boy. From her birth till death, her mother hid her gender in order to get Ros her dad's unconditional love. Day by day she grew more and more outstanding, superior than any other boys in the capital. So her mother thought that, now even if her gender was exposed Ros won't lose anything. So at the day of her adult ceremony she revealed her gender with pride. But, contrary to her expectations, Ros faced her father's wrath, her mana veins were destroyed by his own hands and she got the only gift of her adult ceremony- 'Death'.
But this wasn't the end. She reincarnated in another world where also the mana was abundant in the air. But here also her father abandoned her as soon as she was born. The sole reason- she was a girl. Moreover, after loosing her father's support, her mother's clan imprisoned her and her mother because of committing a felony of marrying a different race. That's right. She was a hybrid between a Werewolf and a flower fairy.
Years later she somehow escaped the imprisonment only to be accidentally transported to a different time and space, to the era of interstellar, where science ruled.
Here, no one knew her. She didn't have to care about her gender. She renamed herself as Andrea. Now Andrea will show that being a girl is not someone's weakness. She will shine as the brightest star surpassing everyone with this identity.
Oh, and here, she also met a certain someone who would overturn the whole interstellar just to gain a bit of her love.
